AR 15 handloads: Difference barrel length makes?
I have loaded for my Remington 700 in .223 with 24" 1-12 twist for years. 50 & 55 gr
Just started loading for a WW15 with 18" 1-9 barrel. 55 & 60 & 62gr
I understand the loads have to be a little hotter because of the gas operation bleed off and less acceleration time in the barrel on the 15. Looking for your experience and tips.
