I shot this buck with a RCBS-270-SAA, the only deer I have shot with a Keith bullet.
I have shot close to a dozen hogs with 44 and 45 Keiths. They always killed fine for me when placed properly.
I can't lay claim to JJ's bear counts, but I never see mentioned the distances he shot all of these bears. I believe they were control issues, so I believe him shooting treed or trapped bears would help them open. Something I've found not to always happen as distances get longer....
Then again, I never seen any deer sized stuff run away with cast flatnoses in the vitals.
Idaho, thanks!
