Thread: Powder of choice for 18" 308 with 125gr - 155gr projectiles?

My Kimber 308 is getting an 18" barrel chop so a suppressor isn't to unweildly. Haven't started any load development yet but probably want to try either the 125gr BT or 155gr Amax as an allround varmint to fallow deer load. Greg Duley seems to be getting great velocity from H335 powder in short barrels - Any others worth trying with this combination?
The other question is brass - I can use Winchester 308 which has about the largest case capacity for readily available brass meaning I might be able to stuff some more powder in or go with Lapua & get great brass life but maybe not quite the same velocity. In a short barrel this may be a moot point Anybody used 110gr Vmax's on anything - looks like the BC of a trash can but maybe a fun splat load on rabbits out to 200yd's for shits n giggles.
