Making up some loads for a Ruger MKll Ultralight in .270 using 140 grain Nosler Ballistic Tips. Have tried Alliant Reloder 22 and IMR4831 so far, though only loads near the top end of the spectrum. Neither powder showed very good accuracy in the ammounts I used them. Will be trying some IMR or H4350 next. That appears in numerous publications as the one for accuracy for a 140 grain bullet in the .270. Anyone have any pet loads they would like to share with me? using CCI 200 primers

I've never loaded .270 but for the loads I have workered up seem to get the best accuracy with a hot load up to max sometimes only changing the charge by half a grain sometimes 10ths of a grain to get one cutting bullet holes an have done well with case length that still fit in the mag

No matter what caliber, I usually start at the middle of the suggested powder charge and then load 3. I increase the charge by 1/2 grain until I reach the max listed. I then shoot 3 shot groups going from the lowest loaded to the highest. I also give the barrel plenty of time to cool down between groups.

You are using one of the heaviest bullet weights, so I would tend to stay with slower burning powder. I like the Reloader powders and they have performed well for me. Try the RE 20 & 17. Good luck and keep us posted on how you are doing.

I have been trying out different stuff for my .270 for my deer hunt coming up. I think I've decided on 58.6 gns RL-22 with a 130 grain Hornady SST! Tried the IMR 4350, I liked it, I just ran out of it. Also heard its extremely temp sensitive.

Both my 270's like 58gr of H4831 under a 140gr accubond. It is a max load by my book, so work up to it.

The Ruger American with a 22" barrel gets 2925fps from the load and the average of three 3 shot groups testing it was .625"

The custom gun with a 24" barrel gets 2950fps from the load. I've shot 4 groups with it so far, cleaning between them, and has made 3 ragged hole groups. The other was about 1.5" but I think it was due to me and the wind that day, it was wicked.

I use Winchester Lg rifle primers.

I've had this load since 1965,h4831 59.5 grains 130 nosler partion or the accubond,cci 200 primer,winchester cases in my pre 64, rem in my mod 700. The most important thing you need to do is find the sweetspot with seating depth of bullet.Once there never change that spot.As far as ballistic tips go, i think they are a poor choice for your .270.Just my thoughts,good luck,Larry

I used Ballistic Tips in my .257 Wby and they really blew up and destroyed a lot of meat. Somewhere in this section on an earlier post are some pictures of the antelope.

Bigsky, I hunt elk/deer in Az with a Savage 111 in .270... Best load I have had for accuracy, velocity and the end result taking 3 elk and 2 deer thus far has been in Hornady brass, Nosler Accubond 140g, 49g of H4350 with Federal primers. I know that every gun likes what it likes but experiment, its always fun to try different loads til you find one that satisfies you liking...

I use a lot of IMR4350. I haven't really found it to be too temperature sensitive and I've killed deer using it while it was hovering around zero degrees. Then again I wasn't bench shooting either so I don't know how much of a difference it actually made but those bucks certainly were dead.

I use IMR4350 in my .270 with all bullet weights, I use the data straight out of the Nosler manual. I have never used a lot of CCI primers, they were usually in short supply so most of my data involves Winchester WLR primers. I'm curious about why Larry thinks the Ballistic Tips are a poor choice, I have used them with great success for many years on whitetails and pronghorns in both 130 grain and 140 grain.

I actually just did some reloads for my 270 with cci 200 primers and 130 nosler ballistic tips, i used H380 and it shoots pretty well...

The original ballistic tip bullets were somewhat light in construction, and many times would explode on contact. This usually caused a ghastly wound and on occasion, a lost animal. I was shooting 140 gr. Ballistic Tips out of a Ruger International 7 x 57 while hunting Blackbuck antelope in Texas some years ago. I had a 187 yard facing shot at a nice buck, and shot him in the brisket. The bullet exploded in a red spray. We did recover the buck, and found that one shard of the bullet jacket had somehow severed the aorta. IMHO, that was bad bullet performance and pure luck.

Nosler changed the construction if the Ballistic Tips a few years back, and it seems that the bullets continue to evolve. Not too long ago, Nosler offered a "Solid Base" bullet, which was well received by shooters, until it inexplicably disappeared from the market. I have some .25 caliber current production 115 gr. BT bullets, and the copy on the box reads "Solid Base Ballistic Tip Bullets". I have had no problem with these on game. Same story with the 150 gr. BT out of a 15" Encore in 30/06.

I have had very good with RL-25 in my 25/06, and it might be worth a try in the .270.

I saw the same thing from BT's in my 270 years ago. I was shooting the 140's and lost a buck I thought should have been a chip shot. The next thing I shot with the same bullets was a coyote, the bullet didn't exit on a broadside 150yd shot. I haven't used them on big game since the accubond came out, but do use them for varmint/practice loads. Many of the accubond and ballistic tips in the same caliber/weight share the same BC and shoot the same. I've shot quite a few coyotes with the 270 130gr and 7mm 140gr ballistic tip at some tough angles and the newer ones seem much tougher. They would probably be a fine deer bullet, but I'm sticking with the accubond. If it isn't broke don't fix it.

Just a side note, the 140gr 270 isn't a place where the ballistic tip and accubond have the same ballistic coefficient. Nosler used a heavier jacket on the accubond which resulted in a longer, higher BC bullet at the same weight.

I have 4 .270 Win. All of them LOVE 140g Ballistic Tip/Accubonds over 58g of H-4831.

H4831 is THE powder for the .270, they go together like peanut butter and jelly!

Wow, I never realized the BT had caused so much grief ! The only one I had a problem with was the 200 grain .338. My buddy borrowed my .338/06 to deer hunt with and shot a medium sized whitetail buck at about 170 yards. The hit was just inside the shoulder on severely quartering shot and the core was recovered under the hide on the opposite ham, the jacket stayed inside the rib cage. I called Nosler and complained. Other than that I have killed probably 15 deer and a pronghorn with the .270 bullets and had no problems. About 10 years ago I switched to the 150 grain Partition for my .270 deer hunting load, I still shoot a lot of ballistic tips in other calibers, just got some 125 grain .30 caliber BT's in the mail yesterday for my .30/30AI pistol:)

I checked this part of the Forum (Guns, Muzzleloaders & Ammo) amd found the post I did earlier this year on Ballistic Tips in my 25-06 and .257 Wby. I have a picture posted almost at the end of the thread of a doe antelope with a shoulder that was destroyed. I am going to checkout the box and see what the descriprion says. I normally use Sierra .117 gr BTs in my .25s and thats what I will keep using for deer & antelope.

Those 117gr Sierra gamekings are a great bullet. I load 110gr accubonds for a neighbor's 257 Weatherby. He had great luck with the Sierras in his 25-06 but we didn't know if they were quite tough enough for the Weatherby so we went accubond when developing loads. Sounds like we would have been fine staying with the Sierra from your results. The accubonds are working great though, his load chronographs at 3450fps from his long barrel and is staying under 3/4". The performance on deer at various ranges has been exactly what I've come to expect from and accubond, small entrance, moderate exit, and internal destruction. Haven't seen a shoulder hit yet only lung shots.

Still reading everyone's posts as I haven't checked this for week. Thanks everyone. I have some H4831, IMR4831, Reloder-22 and IMR4350, all ready to test with the .270. I had read the same things about earlier designed Ballistic tips being far to frangible but was reassured but friends using them now they are fine. I also wanted to use them as I thought they had the same B.C. as the Accubonds of the same weight...

Unless Nosler changed something or my memory is off I think the BT has a .456 BC and the AB has a .496 BC due to the thicker jacket making the bullet longer. I don't have my book right here to check it but I think that is still accurate.

the 140 grain BT, CCI 200 Large rifle primer, 53.0 grains of IMR-4350 is doing the trick. 3 bullets touching at 75 yards (all that was available at sand pit by my house today).

My Rem 700 in 270 likes both Nosler BT's and AB's with IMR 4350 and Federal gold medal primers. Also Hornady 130gr SST's being pushed with Reloader 22. The Remington likes the bullets to be long with an OAL of 3.420

I set the bullets to SAAMI maximum O.A.L. They shoot fantastically. If my calculations are correct the 140 grain bullet should be traveling at about 2750 out of the Ruger's little 20" barrel. 4" shorter than the test barrel so I figured take off 150 fps. I hear so many mixed things about the Ballistic Tip. Makes me think I should load some Accubonds, of couse they would have that different B.C... Hopefully the same powder charge would make them shoot with the same accuracy, even if I have to re-sight the rifle.

I bet it would be darn close it you try. I think they have improved the ballistic tip greatly, but the results I've seen from accubonds are good enough I'll never use ballistic tips for big game again.

mcseal2 I just happened to check the Nosler 7 book and your figures are spot on for the BC's of the Ballistic Tip and the Accubond. Bigsky I too have had great luck as several other poster's here mention using H4831SC in a friends .270 I load for him. I worked up his load using Federal 215 Magnum primers. IMR4350 seemed to work as well working up my load using Federal 210 primers. The H4831SC load came first though and it worked so well I just left it alone.

Good. I am great at remembering important numbers with real-world backing like ballistics, other than that I suck at math, LOL. I shoot a lot of 6mm, 6.5mm, 270, and 7mm and know the numbers for most of the popular bullets I've experimented with.

That sounds like a good plan. I have switched to 225 Accubonds in my .358 JDJ, but have a few hundred 115 gr. Ballistic Tips to shoot up before switching the 25/06.

Only in 45 Colt, and on bears. Worked Great!!!! 300 Gr Deep Curl, 23.5gr H110. I have no idea how fast it is going but damn it hits hard. I have always used 300gr XTP's but I can't find them anymore, so I found 6 boxes of these and like them so far. I am sure you were asking for rifle applications but I hope this helps.

I've always used H4831 in my .270 Win: 60 grains with 130 grain bullets & 58 grains with 150 grain bullets. This year I am going to try IMR 4350 with 130 grain Partitions. I seem to get better accuracy with IMR powder.
