Thread: question re a 300 blk or whisper

Lead in a AR is always a funny topic
Heaps of opinions and story's of bad stuff, but no real info ever provided in evidence to confirm it
Anyway, around 10gr of 05 or 07 Is where you will be with a 220 or 240 in a whisper/blackout so case capacity is spot on

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
