hey team, i have a supressed 300win mag with a 20inch barrel. has anyone loaded for one this short? i was thinking maybe keeping them around the 150-180gr range (or would up to the 200s be ok?) but unsure what kind of powder i should use since the barrel is so short. its a bit of a pain being a short barrel but its a nice rifle so i just though i could make some rounds to suit it a bit better since the factory stuff is made for much longer barrels.
cheers
