Thread: Projectile vs barrel length

Thanks for the replies. I probably should have had powder choice in my original post as well!

I suppose one of my concerns is that trying 2208 with 100gr Nosler BT, 120 AMAX and 129HSP the barrel had a light grey coating deposited at the crown.
While using 2209 and 140gr Interlocks and 143 ELD-X the deposit on the crown was black and a heavy scale that could be chipped off with my finger nail but took some considerable effort. This occurred with various powder charges!

That is another conversation that I will "TRY" to help later.
