Ok you caught a typo, nice graphic though.

Excellent article referenced by Parashooter.

Would have been interesting to see a side by side comparison using a barrel that shot A,B,C flat based bullets.

Thanks ! I had not thought about looking at .303 bullets.... and will try the Midway 150g bullets... I wonder why they only list that bullet for 7.62 X 39 instead of 7.62 X 54r ??

I think that is the answer to my troubles.... I am a bit shy about putting a lighter or heavier bullet in without knowing what the powder is...

This article repeats your information Bruce. They say all bullet weights gave good results until 160g bullets started to show some yawing.

Shouldn't be a problem with 150g bullets. Get an average charge weight and reduce it by one "1" grain if it makes you feel better. Just make sure the rifle will cycle with a reduced charge.

if you want to get REALLY silly with light bullets, try 55grain specimens.

Not quite or even close to .311, I am talking about the .224" 55gn soft points inside a .308" discarding sabot.

Some years back, a supply of sabots, sans bullet, and sabots with bullets fitted, turned up here.

Interesting to play with, especially in 7.62 x 39.

The light bullet requires a somewhat faster powder than even the lightest .308 / .311" bullet.

I ended up using powders that one would normally use for pistol ammo, eg. Blue Dot.

Downside is that the bullets group OK at 100m, just nowhere close to where the "normal" ball or soft point projectile goes.

Apparently these components turn up in bulk packs from time to time.

Odd that Midway would list the 150gn job for 7.62 x 39.

Most bullets for that cartridge run 124 to 130gn to achieve working muzzle velocity and port pressure.

If they have a stock of 150gn .310 (ish) bullets at the "right price", grab a swag and play with them. If you are not entirely satisfied, you can easily off-load them to folks shooting 7.62 x 54R, .303, 7.65 Argy / Belgian, 7.7Jap etc.

There are a few bolt guns that use the round. The CZ 527 is at least one I know of.
