Barrel length and twist has everything to do with Subs in a .308.
My R700 5R uses a whole separate Sub load versus my 17" 1/7 twist .308 barrel.
I'm running 220gr SMK's and 190Gr SMK's , issues have been keyholing with my 24" barrel 1/11.25 twist R700.. that will baffle strike a can real fast!!!
You will have to test your loads for keyholing and see what your gun likes.
My short barrel uses 16.3 gr of 4895 seated at 2.546" using 190 SMK and ita a sub MOA all day long, it's 1043 fps.
Stay under 1052 fps for subs and it will be like a rabbit farting.
Trailboss is what I use for my short barrel as well, 12.5 gr. Again just test, gets expensive testing.
