I have just finished my 6br project and I'm currently working up a load shooting 107g smk's with a 30" barrel.
I'm using RL15 and CCI 450 and achieving good velocity,31g = 2930 fps) with no pressure signs at all but.....it seams like my barrel is full of powder residue, i mean overly dirty only after a few shots?
So my question is this,
do i need to load hotter to get a cleaner burn?
or less powder because I'm using to much?
Any ideas?
Many thanks
