This gave me a wicked chuckle. I think I'll need to procure some of these, for experimental purposes.

I’m busted.

That said, it really was designed for deer and similar game. But it’s interesting to note that California’s Fish and Game officers who work with the DEA on eradicating cartel weed crops are (or at least, used to be) armed with M1As stoked with Federal Fusion ammo.....as in "deer Pablo Escobar....."

Score! Academy in Lewisville had one 20 round box of Hornady 150gr SST and the Academy in Highland Village had two. I have three boxes to recheck my 100 yard zero and make sure I can hit where I want with some consistency. Hopefully, that will only take 3-5 rounds and then I'll have plenty for hunting and some spares.

150 gr?

Hmmm, I hope they group well - you mentioned before that your rifle is set up for the SK 175gr.

Personal example - my bolt-gun (Savage w/ 1:10 twist) hated the 150s (2 - 2.5" groups @ 100) but loves the 165s:



Just a heads-up, which I sincerely hope turns out to be a non-issue.

Beat me to it! A 1:10 twist is going to very much prefer heavier bullets, to the point where if I could not find any heavy hunting loads in the 165 grain to 185 grain range, I would just stick with the 175 grain SMKs, which will be effective.

Those 150 grain SSTs you bought would probably perform a lot better in a 1:12 barrel, if you have access to another .308 with that kind of barrel. They’ll also probably shoot well in the 1:11.5 twist of an M1A barrel, although I don’t know if that load is too hot for the M1A op-rod or not.

Try a box of 165 grain Federal Fusion. I haven’t shot any of that in a long time, but I used to get about 1MOA accuracy out of it in the 1:10 barrel on my R700. Your AR10 barrel has a 1:10 twist, so you might get similar accuracy out of it, and the Fusion line was designed for soft-skinned medium sized game .... in other words, deer.

Alternatively, you could try some of the heavier 180-185 grain ballistic tip hunting loads from other manufacturers.

Another suggestion.....

That BCG was NiPH plated by a friend of AndyC's who owns a company that does NiPH plating for the oil field industry, for parts that are subjected to the worst kind of abusive conditions that the industry can hand out (i.e. drill heads, etc.). He did the plating partly as a favor to Andy, and partly because he wanted to see if there might be a new market for his company in plating firearms parts like BCGs.

Is the place where the coating flaked off located on a bearing surface, or is it just on some part of the carrier body that's not in friction contact with other surfaces? If it’s not in contact with other parts, it might be cheaper to just let it go and see what happens. If it is in contact with other parts, then maybe the guy who did the plating in the first place could be persuaded to take another stab at it.....maybe even for free.

Just a thought.

Also, not all AR10s are the same, internally. If you decide to replace the carrier, you want one that will work in a heavy DPMS upper receiver. If the bolt body itself is ok, I would not replace it or the small parts like the firing pin, etc., and only replace the carrier body itself. That bolt was assembled and fitted by Noveske and uses their parts. If the bolt itself is OK, I’d leave it alone.
