Norma #510 bullets

[Dinny]

I just used QL to determine IMR4198 data for this 77gr Norma bullet. Please verify before you load and shoot this load (if you can even find these bullets).

COAL: 2.040", bullet length .720".

I adapted the Norma 80gr FMJ RN profile to the 77gr PSP bullet specs. 28gr of 4198 seems to fill 97.5% of the case, produces ~50K psi, and might get me near 3100fps with my 22" bbl.

Thanks, Dinny
