Thread: .303 Reloading help

The 125 gr sks bullets are excellent in a 303 I feed a no4 mk1 and a martini carbine with them. Both shoot quite well, the no4 is a 2 groove longbranch and does 3 inches at 100 yds, the martini which is badly eroded in the throat initially shoot around 6 inches. I found that all the powder was not burnt in the martini till I got to 45 gr of 2208 (started at 42) and that accuracy improved at this point to about 4 inches. Both have original sights and that's probably as good as you will get. Both these actions are quite strong compared to the no1 action but start low and work up as steven says. The ADI book says start with 45 gr of 2208 but that's my maximum.
