I'm sure that this question has been asked before but I'm going to do it again. I recently purchased the M&P-10 Compliant model with 18" heavy barrel with a 1/10 twist. Our deer here in LA aren’t as big as they are up north so I've decided on the 150 grain bullet. Is there anyone with enough experience that could recommend a specific round that shoots well in this configuration?

Best deal price-wise and as to consistent performance in the field, Winchester SUPER-X for Deer, Hog and anything else you can hit !

Good ol' , tried & true Remington 150gr PSP Core-Lokt , Federal Hi-Shok or Winchester Power-Point.

I have shot the Hornady American Whitetail
It shot well and uses Hornady's 150gr interlock

So far, I have shot one 115# doe and one 170# buck with Winchester 150 grain PowerMax Bonded. I did not have to track either deer. The price is only a $ or two higher than PowerPoint.

Through my M&P, the 150 grain just does not group worth anything. For the 168 and above, it does very well.

Course "Minute of Deer" is a different story. Every load that I put through it, including the steel case ****, would easily be accurate enough to hit the vitals and drop a deer.

Mine won't group any thing less than 168 gr either. With 150 its all over the paper. 168 or 172 less than silver dollar size at 200 yards.

I let a friend borrow mine for the weekend to go out hunting with his dad and he used the Hornady 150 grain SST. He shot a little 6 point out about 60 yards away and it was DRT.

The 150 grain don't group that well for me, but at that range, not a lot can go wrong.

I went with the Hornady 150 grain American Whitetail loads that easily shot 1" groups at 100 yards resting on my backpack. I slammed a cheap Cabela's Pine Ridge 3 x 9 scope on it until I save money for better optics. My son took the Compliant model MP10 to Sornora, Tx this past week and bagged 2 whitetails and an Axis. The loads carry a wallop and dropped all three animals in their tracks. Great shooting ammo for around $23.00.

I can't speak to the use in ARs, but out of my Savage bolt gun the plain vanilla 150gr Federal SPs group into the 1 1/4" range and they work very well on the last seven deer I have shot with that gun/ammo combo.

Try several brands and bullet weights and shoot what the gun prefers. In my experience 165 grain bullet is more accurate.

The fun of picking any deer round is to shoot it enough to see how well it works in your personal gun. I like Barnes all copper bullets, and for deer the 130 grain bullet would work just fine. But as its been said above buy a bunch of different types, and see what works best in your personal gun.
