Designing the 2-diameter paper patch bullet.

[Don McDowell]

My 40-70 shoots the BACO .400 diameter 360 gr "creedmoor" bullet the best and most consistent of anything I've tried thru it to date. I still need to work with my new dual diameter bullet a bit, but time seems to be the biggest factor, and if I have the time to go shoot some test loads seems like the weather is not conducive to bullet/load testing.
The 40-90 bn and 360 gr bullet shoots well, and it will hammer rams real good even in the 40-65, and out of the 90 just flat makes chickens learn to fly. LOL
I think somewhere along the line we got headed down the wrong trail trying to sling long heavy bullets, and not paying enough attention to what the ODG's did.
