1903 load?

Recommended Posts

Waiting the arrival of a new to me 1903 A3 rifle.

this is a new venture for me so looking to those with experience on loading and using the rifle.

recently a close friend gave up reloading and was king enough to give me eight pounds of trail boss powder.

any suggestions welcomed, thanks

13 grains of trail boss with a 170-200 grain bullet is very accurate and fills the cartridge.   Shot them out of 2,4 and 6 groove barrels.  You run out of sight adjustment at 300 yards in the 03A3.   My 100 yard setting is 6.0 on the peep sight slide.
