Hello comrades, I just purchased a Remington 700 SPS SS with a Leupold VXIII scope at a great price. I placed a Bell Carl, stock on it and had some work done to the trigger. I'm planning on sending the scope off to have the CDS dials installed soon as I make a decision on the load I plan to hunt with. I want to make this my long range elk rifle. The recoil does not bother me I've been hunting since I was five (Started my career as my dads bird dog and retrieved his birds, lol) and now am 43. I've been hunting elk and Deer in Colorado and Utah. I killed a nice 5x4 deer and 5x4 bull this past season in Colorado with a Rem, 700, 7mm Saum. It did good, but just wanted something that will hit harder at long range.

So far the rifle prefers 92 gns of RL-25, Nos AB, Fed 215GM primers, Rem brass, and a OAL 3.670. The best group I got was .825 inches three shots at 100 yards with a stiff 10 mph wind. The rifle did not care too much for H-Retumbo with the same bullet and primer combos. The best group with the H-Retumbo was 1.2 inches three shot group at 100 yards the same day. I have not tried any other powders with this caliber yet. I'm looking for a good load 180 grains and heavier prefer 200 grain. I have several 7mm mags and smaller (270 WSM, 30-06) that shoot great and work great for our small frame California animals.

Anyone have any pet loads for their Rem, 700, 300 RUM, similar to mine? If you do can you list the details....If they are max loads I will work up to them, safety first.

congratulations, be sure to chronograph your loads and not go by the book numbers for muzzle velocity, you will be surprised of the difference, also, you will also probably want to shoot the rifle in non wind environment and play with your oal, charge, and primer selection to find "the load". It sounds like you are off to a great start with that group but the wind is too big of a variable to work up a load. I would take your load and load, shoot it through a chrono and see how consistent it is and if it is very consistent, I wouldnt change, powder charge, I would load up 10 rounds right on the lands, 10 .010 off lands, 10 .020 off lands and ten .030 of of the lands, see what groups best the dial your oal from there, lets say it is the tightest between .020 and .010, then same process .013, .016 .019 etc... It takes alot of time to work up the load but in the end it is worth it. good luck and be safe.

I shoot the same action as you but in a 7mm rem mag, I love it!!! i have put in countless hours at the reloading bench and field time before work to get it where it is. I had over 400 rounds down range through this weapon to find my load.

disclaimer, I take no responsibity for the loads you create or the advice i have given. I am not a professional and attempt at your own risk! This has simply worked for me.

p.s. check out kenton bullet drop compensators. I really think they make a great product.

Thanks for the info, hopefully I will find a super good load prior to shooting four hundred rounds.

Been thinking about trying some 185 and 195 grn Bergers, but my max OAL is only 3.380 (Magazine length), not sure if that is long enough to make an accurate load for my rifle. They say the Bergers must be up against or into the rifle lands to for an accurate load.

I run the Berger 185 VLD hunting out of my RUM. I will have to find my data book, but I think my load is something like 97 gr. RL25. fed 215 & nosler brass. start low and work up. If you email Walt Berger (visit Berger's website's contact us webpage) he will email you recommended data.

My first choice for the 300 RUM is the 200 LRX. Second would be a 200 AB. Try H1000 if Retumbo isn't working for you.

If you want to use Bergers, go for the 210 or 230 otm. Anything less than 200 grains is a huge waste of powder, in my opinion.

Hmmm ... waste of time?

Let's see, you can run the 185 Berger to 3200 pretty easy with a BC of .549 G1. THe 200 Accubond at 2950 with a BC of .588 G1.

So you loose little in long-range performance, and reap the advantages of flatter trajectory. They perform well on elk, too.

I think I will be playing with the 210 though this year. Nice high BCs on those!

I said waste of powder. Not sure what you mean by waste of time?

I don't know where you're getting your numbers but they're inaccurate. You can easily run a 200 grainer at 3100 fps or even higher. With a 26" tube I should say.

Flatter trajectory sounds good but the BC on the Bergers really doesn't start to take over until you get waaay out there. Distances people will not be shooting; on this forum I should say. BC means very little to me anyway. I'll choose bullet construction over BC any day. That is why the 200 AB is such a great option for the 300 RUM. Quality bullet, and the BC is nothing to sneeze at. Also, it's rumored that Barnes' BC has been off on their bullets. The 200 LRX is supposedly supposed to be over .6 - If that's the case, the 200 LRX is the ONLY choice for the 300 RUM... in my opinion, of course.

But like I said bigshot, if you want to use Bergers, use the heavies. You'll want the extra weight in that kind of bullet because there's very little to no weight retention in them.

Bottom line: I wouldn't recommend using light-for-caliber bullets unless you have a ton of powder or if you don't shoot much. The 300 RUM is a very inefficient cartridge and a big time barrel burner... but still an awesome choice nonetheless :)

Good info, Elkoholic.

You are right about the waste of powder vs. time sorry about the misquote.

Those are great rumored numbers on the 200 LRX. If they are even close to .6, I am on board! I love those Barnes.

I have had great results with the Bergers on game, without penetration problems (only 30 cal., can't vouch for the others). I killed my biggest bull with 200 Accubonds, and like those, too.

I always appreciate your input, and I am sure Bigshot does too.

Edit:

Sorry, I forgot about where I got my numbers. I load for two different 300 RUM Senderos (26" barrels). Mine I run the 185 Berger VLD Hunting at a chronographed 3204 FPS average. My partner's I run the 200 Accubond at 2985 FPS average through the same Chrony. These loads in these guns have excellent, consistent accuracy. Both use RL 25. I did get some "WOW" muzzle velocities (near that 3100 w/ 200 accubond) in both rifles out of Retumbo, but could not get the accuracy either of us wanted.

I ordered some 200 grain Barnes LRX today (also back ordered the 7mm 168 grain). I will keep the EF updated on load development.

Thanks for the info guys, got a questions for elkoholic307;
Whats your recipe for the 200 grain Barnes LRX.....Im very interested in trying it. I loaded the 180 grain Barnes TTSX, Fed215 GM primers, 100 grains of Retumbo and a OAL of 3.680 (Magazine length). The average 3-shot group at 100 yards was approx. .900 inches. I made some more of the same loads, but just seated the bullets deeper. I'll be shooting them this weekend. From my experience, seems like the Barnes bullets prefer to jump into the rifle lands. With this load the bullets are traveling a little over 3400 fps. A barrel burner for sure.

Elkoholic307

My advice with the 200 LRX and Retumbo is to start at 87 and work up. You may find max to be in the 91-92 range.

My son shoots a .300 RUM and uses Reloader 25, 200gr bullet (can't remember the brand) with great results. Seems to me the load is about 90 grs. Shoots about as good as my .300 Wby, but uses more powder to do it!

Thanks for the info Elkoholic.

Hey Colorado Cowboy, does your 300 Weatherby push a 200 grainer at 3100-3200 fps as well, just wondering. My buddy hunts with a 300 Weatherby Vangaurd, and he wants me to start reloading for him as well. He said the factory ammo is very expensive (approx. $80.00 for a box of 20). If you reload, can u PM me some of your proven loads or put them on here...

I don't load the 200 grainer, as the 180 Nosler Partition I use is just fine elk and my rifle likes it. I'll pm you what I use.

Weird. Wonder why it was removed? Yes, that is a good idea. I usually shoot 5 shot groups with plenty of cooling in between shots.

I average five three-shot groups for my group size for that load. I allow for adequate cooling between groups.

Its amazing what just changing the primers can do to the size of a group. I first tried the Federal 215 Mag Gold Metal primers and got OK groups approx .800 inches at 100 yards. Then tried the regular Federal 215 Mag primers and got the group above. This group was out of my factory plain jane Remmie 700 SPS!! The only work done to it was adjusting the factory trigger to a nice crispie 3 lb pull.

Nice group. Was it consistent? What load did you end up going for?

packer58
02-24-2012, 09:51 PM
Nice shoot'n..........that load looks like a keeper.

As far load testing goes, I also shoot 3 shot groups. For me, 5 shot groups just adds additional presure on the shooter and lends itself to shooter error. With adequate cooling between shots, a 3 shot group should tell you all you need to know. IMO

bigshot
02-24-2012, 10:17 PM
I shot two, three shot groups. The second was slightly larger .274 inches. Average velocity from my chrony was 3,156 fps, 200 grain Nos. Accubond, 92grns of RL-25, 26 inch tube.

The Barnes 180 grain, TTSX, pushed by 100 grains of Retumbo, did much better too. They grouped .320 and .332 inches, velocity was an amazing 3,502 fps. I will be ordering custom (CDS) dials for each load.

IMHO 5 shot groups are a waste of ammo. 3 shot groups is all I do, sometimes just 2 shots will do.

bigshot,

If you are pushing 180s to 3500 you are exceeding safe pressures for that cartridge, even if you are not seeing the telltale signs on the brass.

That is excellent accuracy you are getting.

CC,

I also prefer 3 shot groups, but I like to get an average from several groups, as one or two can sneak by that are smaller (or bigger) than normal.

I agree. I shoot 3 - 3 shot groups. Throw out the worst and average the two

bigshot, I just checked my Barnes Number 4 Reloading manual (the most recent). It has data for the 180 TSX and 180 MRX listing the max charge of Retumbo at 93 grains! The max velocities for all powders range from 3089 to 3180. I had a bad experience once (only a stuck/ruptured case thankfully) from pushing a 270 WSM too fast. be careful.

02-25-2012, 12:06 PM
DrH,

I believe he did use a chrono, as there isn't a manual out there that I know of that shows 3500 for a 180 of any type out of a 300 RUM.

Other than specialized pressure-measuring equipment, the chronograph is the best pressure testing tool available, IMO. If you are way over max speeds, you are likely way over max pressure, typically.

During load development when I'm looking for pressure signs and accuracy, I shoot 3 shot groups of many different powder charges. Once I hone in on what I think is going to be an accurate load, I shoot 5. 5 shots tell me a lot more than just 3.

I have been handloading for many years and have never understood the advantage of 5 shot groups over 3 shot groups, maybe i'm missing something. I'm not trying to start an argument here but let me run this by you.

Your first shot during load testing starts with a clean / cold barrel unless you fire a spoiler first. Your second shot is sent down range a few minutes later trying to keep consistant barrel temps. Your third shot a few minutes later, again trying to maintain constant barrel temps.
What additional information are you getting from the two extra shots that wasn't apparent in the first three, again, i'm just asking a question here and hopefully i'l learn something.

Colorado Cowboy
02-25-2012, 10:10 PM
One thing to remember is that not all rifles will shoot the same place with a clean barrel. My .300 Wby has to have a round shot after the barrel has been cleaned to put it back where it was before. My 25-05 doesn't care one bit if the barrel is clean or not. You need to know your rifle.

packer58
02-25-2012, 10:46 PM
CC,

I agree with that, my 7 mag is the same way. I always shoot a spoiler before my "group" testing of new loads. Elkoholic307 is saying that during load development that 5 shot groups tell him a lot more than 3 shot groups. I'm interested in what he's learning from the additional shots.

Sorry it took a bit for me to reply, I worked five hours overtime today. I obtained the info from the longrange shooting forum and I thought it was listed in my Nosler Book as a max load. My rifle and brass do not show any pressure signs, just alot of recoil. I always check the books before I try a new load, and noticed it was way above max in my Barnes book, so I worked up to that load and it turned out to be the most accurate.

02-26-2012, 02:01 AM
Ok,
Just made it home and checked my Nosler book #6, I was wrong, it list 99 grains of Retumbo as max with a 180 grain bullet and at a listed velocity of 3,343 fps. Wow, BB must be right, and just way too much pressure.

I prefer the 200 grain Nosler Accubond load anyway, so I'm going to stick with that load. Thanks for the heads up guys.

Bitterroot Bulls
02-26-2012, 08:36 AM
bigshot,

The Barnes bullets are solid copper. Accubonds have a gilding metal jacket. Barnes also have relief grooves. These bearing surfaces are very different, so the data used for one is not good for the other.

Those group sizes are downright spectacular in a sporter. Keep that gun.

I shoot a remington 700 Sendero in 300 RUM and did a lot of load testing before I found my load. It is 93 grains of retumbo pushing a 208 hornady
A max 3100 fps. It groups amazing with my best group being .514'' at 300 with 3 shots. Many people will say its not a hunting bullet but they are wrong.
Between my cousin and I we have killed 4 deer and 3 elk in the last 2 years with them, and no animal made it farther than 50 yards. And the bc is .648 so
the long range performance is awesome, we shoot em out to 1400 yards.

Hey WA Hunter, how did the Hornady Amax perform on game. You mentioned, you and your cousin took lots of game with them. Do they expand like Nosler Ballistic tips or do they have controlled expansion. Not too familier with that bullet. Did you get an exit on the deer and elk? I found a good deal on some of them bullets and thinking about buying them.
