I have a new 45 cal. Traditions striker fire. The book only shows 50 cal data and says 84 gr(W) /120 (V). But I have read that 45. Cal has a 77 gr by (W) max . Traditions won't answer the phone Or has not for me. How do I know when in strating to get to close to a max load ? Is their tell tell signs ? And would the max powder not decrease with the bullet weight increases?
