110 gn. 308 for 7.62 x 39

[HOWARD J]

I want to load a 110 gn. Hornary 308 for a 7.62 x 39 using IMR 4227 powder. Loading data is all over the place for this.
Any good ideas?

Pick the lowest and work up. They may not be that accurate depending on barrel diameter.
Just don't load up a couple hundred without testing 5~10 first.
Since you didn't specify type of gun you may have some extra work getting a semiauto to cycle.

This thread may help some.

Thanks for the link. I have 2850 reloads for the hornady 125 gn, 310---no problem, A buddy passed away & left me 10 guns & a couple hundred 110gn, FMJ. 308.
I guess I will just have to work up--THANKS

If you gun has a .311 bore it won't be accurate.

i HAVE:
RUGER MINI 30
RUGER RANCH IN 7,62 X 39
AR 15 IN 7.62 X 39
TWO SKS CHINESE

SO WHICH IS THE ONE?

Marvin Stuart 7.62x39 Soviet complete reloading manual pfd .

SKS has .311, some Ruger mini 30's had a forcing cone you can use both . Ranch mini 30's most were .308 , AR's can't say because I've had both, I like the .311 dia.
Because I could use cheep ammo.

I have used steelcase in all of them--works ok

I tried some loads with 4227 and 110gn .308 bullets, in my Ruger Mini-30. Accuracy was terrible across the charge range. Even though my Ruger was an old one that everyone said was a .308 barrel, when I finally got around to slugging the barrel I found out that it was, in fact, .310. I don't know if that caused the inaccuracy, as I did have some .308 bullets that had better accuracy.

110gn 30 Carbine FMJ bullets
IMR 4227, from 18.0 - 23.5gn, in 0.5gn increments
18.0gn = 1717fps, failed to cycle gun.
23.5gn = 2348fps
Shot from a Ruger Mini-30.

Maybe it don't like round nose bullets ?
just kidding. I will be using a spire point bullet @ 20gn IMR4227

 

[Toprudder]

I also tried Sierra 125 SP, Speer 125 TNT, and Hornady 130 SP. The only powder I tried with those bullets was H335. The best accuracy I got was about 1.1 - 1.5" @ 50 yards.

 

[Toprudder]

My Ruger did not work well with lead-nose bullets unless I seated them short. If I seated them over a certain length, then it would shave some of the lead off as it chambered. I also had to put a firm crimp on the bullets, as it would slam the round into the chamber so hard that the OAL would lengthen otherwise.
