View Full Version : Crazy idea, take 2

OK, next idea.

Will a FAL bbl, if properly chambered, stabilize a 7.62x25 bullet?

Bullet specs are 85gr. That's basically half what the FAL normally eats.

So will the 1:12 or so of the FAL spin this fast enough?

The standard rate on a 7.62x25 subgun bbl appears to be around 1:6 or so.

But, isn't it heavier bullets that have issues if the twist rate is too slow?

Edited to add
------------------

What about an AK bbl? These appear to be about 1:7.5 or so!

seems to me that Meeper offered the 7.62X25 as a chambering, I dunno what barrel he used tho.

I KNOW there is a guy on here that has one, I just cant think of who it is :cry:

Mine is 1:12 very accurate out to 200 using 85-90gr pills @ 1850 fps. I do plan to try some 95-110gr and get it to about 2000fps.

I have a "para" rear sight and it seems to be perfect for it. I use the short range for 0-100 yards and the "L" for the 200 yard shots. I tried it on the gongs at Falfest thursday night and it was a hit every shot.

Jerry, is this a typo or are you just running sub-loads with the 85-90's??

doesnt seem right to increase weight AND velocity unless you are running powder-puff loads to begin with.

I wish I had known you had the rifle at Falfest, I would like to have seen it :(

maybe next year?? :biggrin:

How about a black powder FAL....in like 75 caliber, or something?

Kinda standard loads with the 85-90's. 16.25" of barrel will do that with Romy surplus.

I do want to try some 110gr bullets and after looking at the charts I think 2000fps is about max for the cartridge but I want to try just to see.

I will have it next year at Falfest. It keeps getting better but it is still not 100% in the reliability dept. It is a hoot to shoot.:biggrin:

Short, squat pistol slugs don't need much twist. 1 in 20" would be more than fast enough to do the job. The .308 barrel won't give you any problems.
