38-55 cal. Loading Question
I own a 1894 Winchester 38-55 cal. .380 bore 26" Oct. Barrel made in 1904.
I shoot a 280 gr. gas checked cast bullet. The load is 21 grs of 5744 powder.
The load is very, accurate in this gun. 1" groups at 50 yds open sights. 1.5" groups at 100 yrs. The bore is perfect, the problem I am having is this load leaves alot of unburned powder in the barrel. Would using a magnum primer help? Or maybe increasing the load 4 or 5 grains? Any suggestion I will appreciate. Merry Christmas to all.
