Accuracy of Subsonic 7.62x39 in AK

standard bullet is 123 grain. Will 200 or 220 grain subsonic handloads have acceptable accuracy, or will the bullets keyhole as soon as they leave the barrel?

What is a cheap source of of components for 7.62x39?

Aluma-Hyde II vs. Anodizing

I'm going to make a monocore suppressor out of 6061 Aluminum. I don't have the equipment to anodize myself. How does Aluma-Hyde II hold up?

...I got around this by hanging the core between both the base and the rear caps using tapered rings that register the stack dead center. There are better ways to do it, such as by making the monocore and base cap as one unit, with perhaps a viton o-ring at the very bottom. Unscrew the end cap, whi...

How quiet are Supersonic rifle cartridges

I want to get a suppressor for a rifle, but am wondering how quiet would a supersonic bullet be? If I really want to get quiet, do I need to stay subsonic? If so, would it make sense to get something like a uzi carbine or other carbine that shoots a pistol cartridge?

If you expect or desire a large volume of .22LR fire and want to clean the can (both of which I do) then would it be possible to create an annular space between the core and the tube wall? Mine has a gap of about 0.012". In other words, if the ID of your tube is 1.000", make the OD of the...

...You can prevent this by: Minimizing the blast expansion chamber size, running the can wet or simply blowing smoke into the can (if you smoke). I think it's better to do a good design than going back to smoking or drop some Coke into the can ... (joke) ...For the Blast, best result is 1 or 1.5 ti...

Newbie here - can you explain what you mean by Buum or FRP? Out of a pistol I think even high velocity 22LR will be subsonic. What is th...

From the FAQ section: Can I post Images? Images can indeed be shown in your posts. However, there is no facility at present for uploading images directly to this board.
