Spanish Mauser 7X57 reloads
I have a sweet looking 7X57 M1916 1931 Spanish Mauser that seems to be in nice mechanical shape. It has a nice clean bore with crisp rifling but doesn't shoot as well as I think it should. I've never grouped better than 12 inches at 50 yards with reloads. Factory ammo was worse.
My reload formula includes using flat based 7mm 139 grain .284" bullets and 1 grain over the starting load of BLC-(2) powder.
I also have a 1944 Lee-Enfield No. 4 Mk 1* that's also in nice shape mechanically that didn't seem to like boat tails but will shoot flat bases very accurately also with 1 grain over starting load of BLC-(2) powder.
Has anyone had better luck with a different 7X57 reload formula than what I'm using?
