I drew a Wyoming bull moose tag and I'll be both bowhunting and rifle hunting the unit. I currently shoot some 90 grain 3 blade Muzzys with carbon arrows at 73lbs(older bow). Are they enough for shiras moose or should I switch to something heavier. The Muzzys I have have the nice practice heads so I like them. Thoughts...thanks.

Those heads will probably work just fine as long as you put em in the sweet spot. However, I'd be looking for a little heavier head with more integrity for moose. If you like the Muzzy product line check out their Phantoms. These are a very tough head and should shoot as well as the 3 blade Muzzy's. Congrats on the tag!

Thanks, my arrows weigh 350 grains. Is that too light, would 400 be better?

I think this is a good read.

Gillingham really knows his stuff

This is from the gold tip website


"Do I need a heavy arrow for hunting out west?
No not really. More elk and mule deer are harvested every year with a 5575 in their lungs than just about any other arrow size. Weight does not necessarily mean penetration. I would categorize the following things to be most important for penetration.

Shot placement is number one. You hit the animal in the right place it will go right through. If you hit the opposite rib dead center at 50 yards on an elk, you probably wont blow through even if you are shooting 80 foot pounds of energy and a 430 grain arrow. Set you bow up with a reasonable amount of speed that will help with yardage errors. That will be the biggest factor for great penetration and good shot placement.
If you are going to change anything from your deer hunting setup to your elk hunting setup, change your broadhead. Use a broadhead that is more sloped and uses a less choppy action of cutting. Although many kill elk with 2 cutting diameter broadheads, being a little more conservative and option for 1 1/8 to 1 3/16 is a little more realistic for reliable penetration.

Good arrow flight is paramount for good penetration. Loss of energy due to the arrow striking the animal any thing less than perfectly square will result in penetration loss as the energy is not expended directly down the center of the shaft. Make sure you bow is paper tuned very well and your shooting skills up to par.


Weight consider for me is only a happy medium. I like a 400 grain plus arrow but mainly to help with longer range accuracy and shooting in the wind. I would not shoot my bow below 280 feet per second just to make sure I shoot the magical 400 grain arrow. I would go to a lighter arrow or a faster bow."

My take home from this. Make sure your arrow flight is perfect.

I shoot a 428 grain arrow at 284 fps

I would also add I feel 350 grains is light

Thats what I was thinking, maybe switch from a 90 grain to a 125 grain to get to 385 would help.

I like the Montec 100grain CS or 125 Stainless Steel. Arrow weight should be between 400-450 grains. I have done tons of reseach about this and most reseach showed that 400-450 was where arrow weight and speed produce optimal kenetic force. Congrats on the draw and good luck

Your set up is lighter than what I would use for moose, but they may work just fine. I thought you might find this video interesting if you haven't already seen it. Do a search on YouTube for " Gel with shoulder blades" and watch the test of eight different broadheads.

30 Hart, adding 35gr. to the end of your arrow could have a negative effect on accuracy and overall performance. Depending on your current arrow you could easily go underspined by adding the weight. Pushing an additional 35 gr. will definitely make your current arrow act weaker.

At 73 pound draw, I am guessing the spine of his arrows has to be a minimum of 340. I've shot a 340 spine arrow at 72 pounds with 125gr broadheads, and they flew fine. You are absolutely right if the spine is much weaker than that.

Well I went with the 125 grain all stainless Muzzys. With a 435 grain arrow I'm getting 276 fps for 72.5 KE, that should work for moose. Shoots a litte tighter than the 90 grainers...bonus.
