Home Forums Hunting & Shooting AR and Tactical Rifles 7.62x39 in the AR-15

I think anything .300 BO that isn't subsonic is dumb.

But to each their own.

I load my 6x45 in nickle plated brass just for this reason. Fortunately IME 6x45 doesn't seem to chamber in a 5.56.

the .300 BO is sorta like an M1 Carbine on steroids. And uses the same bolts and mags as the 5.56.

I run my .300's at mag length, which makes them way too long to chamber in a 5.56

getting old i guess, i should have thought of that. my eyes can't pick up the size of the bullet like they could 40 years ago.

That's OK, most of the other things you say are dumb too; we're used to it.

I have one and I've been reloading for it too 30gr of CFE BLK with a 123g VMAX runs 2450 in the Ranch's 16' tube. Only shot at 50 yards so far, but a 10 shot group is about the size of a quarter.... My C39V2 AK with the same load prints only about 3 inches....

Also tried a 150gr Sierra FP (.308 for a 30-30) and it's clocking 2300 with 26gr of CFE BLK with 10 shots around 2 inches. I'll try this load hunting WT's this year.

That's pretty good. I wonder how much more the Howa 22 inch barrel would give.

Feel free to make the case for supersonic .300 BO ammo.

Probably only 50-100fps. The Hodgdon manual lists 29.7gr of CFE BLK at 2554fps with a 24 inch barrel. I chose 30.0gr since the pressures are in the 40K CUP range and figured the Ruger could handle it fine.

Seems the CFE BLK powder gets it's job done in shorter barrel lengths just fine.

The 125gr Ballistic Tip works well in it, too, as does Lil'Gun powder

Any of y'all ever use the 125gr Sierra Prohunter in the 7.62x39?
How did you like it on deer?

I see what you did there! Haha!

Heads up, complete uppers for $229 shipped,

https://palmettostatearmory.com/psa...lassic-upper-with-bcg-ch-5165449462.html

I'm toying with the idea of buying one of the PSA uppers to play with.

I have had a set of Hornady dies on the shelf for years, even though I've never used them, and the dies have two expander balls, one of which is .308......which got me to thinking.

I have a BUNCH of 150 grain winchester silver tip bullets, made for the 30-30, that I got in an estate......and they measure .309......what are the chances that these bullets would shoot halfway decent out of the 7.62x39 upper??

From load data, it looks like I might be able to get them to +/- 2100 fps......if so, any guesses as to how they would do on pigs at 100 yards or closer??.

I'd think the 150gr Silvertips would be great at 100 yards on game. The only question marks would be accuracy and feeding.

Put a Primary Arms 3X prism sight on this thing. I didn't want to, but my eyes aren't what they used to be, and bifocals don't play well with iron sights.

So, got it zero'd in (Tula 122gr FMJ), and did some ranging with the laser, and shooting with the reticle. Pretty good out to 510 yards. Not a target rifle, but for hitting torsos, it would be effective.









Scenery today,

Nice.

Good info and nice pictures, thanks MM

have used a hornady bullet 123 gr................ worked great
