M&P 10 accuracy

I think if you got PMC down to 3 inches you did good. If the barrel smoothing thing is what was recommended and you have the funds try a few boxes of XM80. Its bi-metal and get you some big targets and go enjoy yourself. I have an M1A that aggravated me really bad but when I finally decided to pull off the scope and burn through a few hundred rounds of xm80 on milk jugs I enjoyed myself more and the rifle smoothed it self out as a result. Hope it works out good for you. You'll like Australian ammo if your rifle is like mine.

Hi and thank you for your recco of the Austrailian. It looks to me they are running the Sierra bullet in both 165 and 168(game king, match king). Can you confirm?

I found a listing for them on Cheaper than Dirt and they were not terribly expensive. Def worth a try.

At $14 per box for the Freedom Munitions reman 168 amax and only slightly more for the HPBT Match, which once again appears to be Sierra, these are also options. I am cheap! but within reason, you know.

I have not yet found a good supplier if xm80 to try. Do you know one to recco? I tried that ZQI stuff which is supposed to be nato spec ball, it sucks! It runs but it sucks in accuracy it seems.
 
We'll everything is here and my scope is mounted, the good folks at the Post Office haven't received my Geissele's yet they we're supposed to be here today. Always have issues with USPS. Anyway hoping to intercept them early and get em installed on the M&P 10 & 15 before I head out. I'm gonna strip the rifle and clean n lube it tomorrow before we go. I checked the barrel and found no "rings" or excessive stamping at a quick glance. I'll check again tomorrow. Gun looks to be made well and I'm exited


Also I opted for a pair of the Geissele G2S's instead of the SSAE's.


As far as my ammo selection thus far your correct cope, it's not duty ammo I just figured I'd put it through its paces n see how it ran or what it likes and dislikes. It's got a ways to go before it sees my squad car. For now it's my M&P 15 and an old school 870. I'd love to see this rifle meet my requirements before it sees any duty usage. Wish me luck fellas!!!!

Yes, the Australian are Sierra game king and match king. I ordered 2 boxes of each from CTD initially. The game king shot so good i ordered 500 rounds the next day while it was cheap. I bought 1000 rounds of xm80 from palmetto state armory with free shipping a year ago when i got a M1A. Got 500 of that when i think it was priced wrong (40 cents per round) and the price went up to current bulk prices the next day. Palmetto state is ok when their free shipping is going on. My experience with zqi is like yours.

I've saved every piece of brass I've shot so I imagine that I'll be reloading maybe next year.
 
Got the triggers installed, goin shooting. Will report, also got a box of PMC NATO spec for laughs. Not expecting much but maybe ill get lucky???
 
I've purchased the Australian Outback 165 & 168. I'll also pick up some of the Hornady Amax. After it warms up a little here in Wisconsin, I'll make the first range trip.
 
Ok so here are my limited un scientific findings. I know its not what your looking for but here it is


Shot the Nato PMC to get on paper and zero in the scope at 100 yards. No failures of any kind and wasnt upset with the accuracy. Just kind of felt the rifle out with these 147 grain.

Then shot the American Eagle 150 grain and at 100 yards i had a dot torture target set up. I think the circles are 2 inches (please correct me if im wrong). The first 10 shots stayed in the "dot" and so did the next set of 10 shots in the dot below, but i had two rounds out of the twenty not cycle. Most likely because i didnt have the rifle shoulderd well. I shot off a rest and that was the feeling i got on those two, more my fault then the guns

The next ammo fired was the Rem Core Lokt 150 grain.This time i fired 1 string of 10 shots on a new dot torture target all shots but 1 stayed in the "dot" no failures of any kind


The next 10 rounds were the federal 180 grain. 10 rounds fired,7 of 10 were in the dot the other two just outside.

The errors you see were me and not the gun, barrel was nice and hot dont think it made a difference as i have very little experience with shooting set up like this

Due to time constraints and my buddy wanting to put me through some drills with the M&P 15 thats all the 308 i fired. I figured id go again next week and shoot the "better" ammo. Really the only minor issue i had was the 2 AM Eagles that didnt chamber, but prob my fault as everything else ran great


Attatched is the pic of the Core Lokt (top) and the 180 grain Federals bottom. Ive got alot to learn but for someone who has very little experience with this platform and scope set up im pleased, didnt think to snap the pic of the Am Eagles like an idiot but both dots looked like the Core Lokt photo. I will next time before i shoot the good stuff as im dying to know if my rifle will digest these... I think it will if i snug up to the rifle

Not too bad. Sounds like you have a winner.

I like that target. Can it be downloaded and printed?

I think you did a fine job shooting those groups, there is a little more oomph! there with each shot. I had a problem with my RR 5.56 initially which was throwing a flyer or two each magazine, and it turned out the to be the ASC 5 rounder that I use, was dinging my bullets as they chambered??? thanks to Hill Top Gun Shop for helping me sort that.
Switched back to a couple of factory Colt 20 rounders an problem solved..

magazines are the first place to look if everything else is up to snuff, but I think you will be very well pleased when you get to the heavier ammo? my Rock is a 1 in 8 twist and it def prefers heavier bullets.
 
Look forward to some more testing. Had a great time with it and thanks for all the kind words. Gimme some more of your stories fellas. Love hearing about the new rifle
 
I have had all kinds of hell finding any common stuff to shoot straight in mine. I would not expect a lot out of the core lok or any of the 150 stuff for that matter. I ran some 180 gr early on and got nothing better than a 6" splatter at 50 yds. Best group on that day was with cheap Tula steel cased at less than half that.

Having suffered through a number of disappointing tests now over a year in, it was only last weekend I seemed to manage 1.5 groups at 100 using the Federal GMM 168, and the AE 168 OTM bullet marked for M14 was just about as good and much less expensive. I believe both use the Sierra 168 hollow point, yet the powder measure on GMM is more consistant.

The Game King is a premium bullet for hunting, not sure just how that may fit into a LE profile, because military cannot use it. They use the OTM as I understand. (open tip match)

The Hornaday Amax and Vmax are also premium bullets. I have some ordered some 168 Amax at a reasonable cost from one supplier and there is another quality reloader near me which I may try as well.

There are a lot of variables, and powder and charges are key, which is the reason accuracy loaders have to load their own, but I am with you on the pie plate thing, if I can just get there at 300 I am a happy camper, but your mileage may vary!

168 grain and 175 grain seem to be the preferred weights for LE from what I've been able to discover in my research.
