Shot the original punch in 510 and 45. Tested in many things.
I say original as in Belt Mt and not grizzly.
They would hold up to almost anything other than rocks. And even then kinda surprise ya. He beefed up the nose on some of the first ones as he found a problem there but once in final designs, they were pretty must perfected in my opinion.

HERE IS A CRAPPY PICTURE OF A .452 PUNCH BULLET RECOVERED FROM A CAPE BUFFALO IN 2009. ONLY MARKS ON THE BULLET ARE THE RIFLING. THE RIFLING BARELY TOUCHED, BUT DID REACH DOWN INTO, THE RELIEF GROOVE, MAYBE THE RELIEF GROOVE SHOULD BE SHALLOWER? or MAYBE DEEPER?, i.e. IS IT BETTER FOR THE RIFLING TO TOUCH MORE, NOT AT ALL or OK AS IS?

It looks like there were hot gasses flowing up the rifling cut on the bullet.

I believe after testing these things, the relief is fine where he set them. Might be more important for metal fouling than anything else. One thing for sure, they work as is for the velocities revolvers generate.
Not sure it has been mentioned but the nose was designed as a rule breaker for Alaska I believe? Somewhere that non expanding are illegal. That’s why the tiny hole in meplat.

Isn’t the pin hole in the meplat considered a “hollow point” so it’s not classified as a solid or armor piercing handgun round.
I’ve never seen anything that says what size the HP needs to be

Trying to walk the line on different countries laws is a razor thin line. Some will not accept HP designs and others solid non expanding, having both designs maybe worthwhile. Having seen firsthand, hundreds of rounds confiscated by border police because they were HP design.

It looks like there were hot gasses flowing up the rifling cut on the bullet. My FA has a bore that is larger than I would have expected. I do not shoot 451 or 452 lead bullets as it needs a 454. Have often wondered if this could account for the reason so many say their FA is most accurate when pushed very hard with top and loads. Is that because their undersize bullet needs to slug up? Could that account for the gas cutting your observing? |

I always assumed the hole was a vent for putting the core in.

I know they don't cut the chambers as tight on the Colt 97's as they do on the 83. |
