Hi all,
Looks like I'm gonna get a 20" .308 and I've never reloaded for the "shorties". I'm used to reloading for 24-26" barrels with better than average results. What will change with the shorter barrel? Say my standard load in a 1:10" 24" 308 is 42 grains of Varget under a 168 ELD-M. All things being equal, can I expect that load to perform just as well out of a 20" bbl? Is it likely that I'll have to switch to a faster burning powder?
I've also read that some of these short barreled .308's like the heavies (175-178 grainers) which seems counterintuitive to me. Wouldn't a shorter tube have a harder time stabilizing a heavier bullet at a givin twist rate?
