Just recently built a AR10 .308 with 1:10 twist. Any opinions on what grain to use? I will be using this rifle to hunt whitetail. I’ve heard of grain range 150-170. Have been looking at Hornady super performance 165grain. Any suggestions appreciated. Thanks again.

Hey max yardage would mostly likely be 250 But 90% of shots are less than 200 yards

I’ve looked at Hornady SST and precision hunter they say they are very accurate but have seen a lot of people say there was poor performance in closer ranges, no blood trail and deer walking off etc. Might take a look at ballistic tips as Seuss mentioned. Saw the Remington introduced a newish Remington core lokt tipped

For deer I don't sweat ammunition too much with a 30 caliber. I've found cheap Federal blue box does a good enough job. I used to buy premium ammunition and I think it's overkill. If it was a caliber questionable for a deer I would spend the money.

Try as many as you can and see what the rifle likes. 1:10 might like a heavier bullet (180gr maybe?)

I’d start with 165/170gr and see what you can do.

I agree with trying different stuff to find what the gun likes. deer are not tough and 250 isn't far enough to worry. My AR did not like 150's but once I threw in my 178 eld m load, the gun was happy. that was this particular rifle, I've also had 125 noslers shoot really well in others. both will drop a deer quick as long as they hit where I aim, and that's what really matters.

For deer, 165 Sierra Gameking. I dont carry my sentimental 308 as much as I used to, but that combo has always performed. Plan to try out the tipped version one of these days.

Thanks everyone I think I’ll take the advice of buy a couple different grands and grains will start with the 150 and 165gr and see how it goes. Thanks for all your help. Will
Post some results after I find what my rifle likes

My AR 10 loves those inexpensive winchester deer season XPs (150gr), lethal on deer too
Yeah I have been looking at the Winchester XPs and the American whitetails. These may be a good option cuz I’m not looking to break the bank with it being a new AR and unsure what it likes. Hopefully I’ll be lucky and it will shoot 150 or 165s well
