Cast Bullets in DPMS LR 308--Can it be done??

[ADKWOODSMAN]

Anyone have any experience with cast bullets in LR 308.

Should a medium burning powder such as IMR 4895 be used as in M1's?

The Bullets are 165 gr. cast hard.

You are going to have a heck of a time getting the gun to cycle reliably with the sub 2000fps loads that you will need to use to avoid leading up the gas system. I can't see it working even with a gas check.

VegasOPM--never had a problem shooting them in my Rem. 742 with a gas system. IS this similar?

I' need all the info I can get, thanks.

I don't know about 308 but I know a few people that tried to shoot lead in a 223 AR and had to remove the gas system to clean it after only around 20 to 30 rounds.

Rusty, thanks, it's the type of info I'm looking for.

You want to go to cast boolits and ask there. I wouldn't worry as much about leading the bore. With proper fit, lube and hardness you can exceed 2000 fps without leading, and some guys get 2500 +.

However, the gas tube may be another story altogether. The guys at cast boolits will know.
