I have an itch for a lightweight deer/coyote/occasional rock chuck rifle. Of the standard calibers .308, 7mm/08, 243 is there one that performs better out of a 20" barrel than the others? Along the same lines do slightly faster powders work a bit better than standard powders for a short barrel? Thanks.
