300 Whisper AK - Just found a gas block that might be a good start...

I don't want to get hit with either one. I am too fragile to be hit with a VW or a semi. Ya pays your money and ya' takes your choice. It is funny how many guns and calibers there are. I am in favor of a pack howitzer myself. Not sure how I would pack it but what a round that would be!!!!'Wonder if I could get a subsonic one?

There sure is alot of new cartriges today, funny thing is that most of the new stuff was tinkered with 100 years ago just get Po Ackleys book. This biggest thing to change is the selection of powders. After it is all said and done marksmenship is the one thing that can't be replaced.

I have not done anything with this project but if I could get some 5.45x39 brass and resize it to .308 I am thinking that a 240-gr bullet in that small case should perform similar to a 300/221...

I just have not had the time lately to do much beond work and family

My experiance is limited to the 300 Whisper, 9.2 grains of H-110 gives me 1050 FPS with a 240 grain Sierra. Small amounts of powder with this small cartridge can make large pressure and velocity differences. You also need to make sure your projectile has enough balls to make out of the barrel.

well there is 60g differents not that anything could tell when hit by it the idea is to come up with a sub sonic round that will work in the ak this got me thinking i found some 220g in .311 and loaded them with whisper data they fire ok but at 7 moa they suck i think its the twist of my ak oh well with the 180g im getting 2 moa in my ak and 3/4 moa out of a cumstom 700 i have in 7.62x39 dont get me wrong i love my whispers have for 15 years but the 7.62x39 will do the samething with good loads and im sure that 180g bullet at 1035 fps will kill anything i may run into

Hornady makes a 178 gr. A-MAX. It's a .308 bullet so it might be iffy in a .311 bore (paper patch?) but it's a target bullet with similar construction to the V-MAX varmint bullet so I'm curious to see if it expands at 1000 fps.

Dave what is the twist rate on an AK, my web search came up empty. My SKS seems to be 9.5:1.
