Thread: question re a 300 blk or whisper

Thanks Spanners,

ive had a heap of conflicting info on Lead in Gas Guns, however one particular clever bugger ran it some time in his with no issue,( i think to be fair his was a mini14 )

the only trick that i have found is to really clean the barrel and remove copper as lead doesnt seem to shoot well from a barrel with a lot of copper in the barrel, otherwise ive really not done a lot to do with semi auto's, except my M305.

The projectile that i intend to use (oneday!) measures 1.254 in lenght with a gas check, that is the 240gr

the powder choices you recommend are 2207 and 2205?

Cheers
