Have a 375 super mag 8 in barrel all the jacketed bullets are very expensive and to heavy a jacket for that vel the lightest i could find is 200 gr sierra i would like to buy some light ones about 170 gr gas check with lead soft enough to open up on deer at about 1500 fp.s I dont see why it wouldn't work a standered weight 41 mag shoots a 170 gr. with about the same case capacity .The gun has a 18.75 - 1 twist and i was told that a 220 gr would be max weight that would shoot accuratly i guess i could go with soft lead gas check but prefer something around 170 gr. although i have been reloading for about 45 yrs i dont mess with lead bullets so can i buy some ,if so where. Thanks
