I have a new taurus 454 with the 8 3/4" barrell. I have 200 rounds of new brass that im itching to reload. but I have a couple questions if anyone can help. Some of the books i have say I can use ,451 and .452 bullets and some just say .452. Has anyone used .451? I have .451 in 230 grn and .452 in 250 grn. I mostly just plink tarkets so i didnt want to go to big for that. My next question is I have alot of unique powder and some bullseye that i would like to use if possible but i have only found one publication that even lists either of these for reloading. Can anyone advise on a load with these powders? Thanks, Terry J.
