I ordered an Armalite AR10 with a 16 inch barrel. What average velocity should I get with 165 grain bullets?

So I should be around 2500fps according to the Link?

From what they did, and accounting for the last 1/2", I would guess 2400-2450fps.

OK Thanks. I will run it through my chronograph. I was just wondering and will be reloading for it.

I've chrono'd 147 gr. BT's out of my 91 and I get around 2625 fps. That's with Nigerian and Venezuelan surplus.

Isn't the surplus military berdan stuff loaded a little hotter than domstic, commercial ammo?

nope -- in fact, never, as 7.62x51 is SPEC lower pressure than 308 commercial .. they are, actually, different rounds - but most people will argue for hours over that

not to argue, but I use the same set of dies, and have never paid attention to the difference between FN, Cetme, my DPMS, or commercial.

don't shoot factory rootin tootin 308 ammo in a cetme - it WILL gain headspace -- and same FALs will, as well

but, then again, reasonable loads in autoloaders tends to reduce the likelihood of steelrain

Based on my testing at APG a 175gn in a 16" gun will be around 2450 to 2500fps.

Nice!

BTW, I have now officially met your requirements. Not only is the smith finally working on my RUM, the weekend before last I picked up a very nice 90s vintage Bushmaster A2 and have the parts on order to build a optics ready service rifle upper.

I also picked up a 1955 year pre 64 M-70 .270 FWT in 90% condition. It has an uncut stock with an aluminum butt plate.

So now in 2017 I am at two newly acquired NICE guns in the second month of the year.........

Load some Moly'd Sierra 155gr Palma's over 43-44gr of IMR 4064 just shy of magazine length in your Armalite AR10's chrome lined Bbl.

Accuracy is less than 1/2 MOA through a 1/2 dozen ArmaLite's to date.

Naked 155's will shoot 1MOA.


Keep'em in the X ring,
DAN

I have the first modern AR-10 made. And the first AR-50. And the first AR-30. All the same serial number.
