I cast a bunch of 260 gr hollow point bullets for my 45 Colt then thought "Why not?" So I sized to 252 and made up a dummy round. Feeds like a dream. Now I am looking for starting load data. Don't want to go crazy but I am thinking this bullet would really beat up a bowling pin.
Would like to USA AA 2, 5, or 7. Any ideas?
The only AA5 data I have is for 240 grain 6.8 to 7.5 from Sierra.
Older Hodgdons has a 260 using HS6 which is real close to AA5 going 7.5 - 8.0
