Great article! I remember the movement back in the 1990’s

Then the really big bores took over, Linebaugh and such. I bought a big supply of JD’s designed bullets already cast, got a deal. But they are plain base 330 gr. Real beasts to shoot past 1300 fps. I’ve not seen any leading as I gave up before it became a problem. I think they were a later design, positively not for S&W, if you cared about your gun.

Working with Gary’s .429 GNR I used the LEE 310 gr. Also with two crimp grooves. A full case of H110 the front groove garnered 1550 fps and the rear groove (allowing more powder) gave 1600+ fps! But the faster load generated enough recoil with that bullet that bullets were just starting to pull by the 5th-6th shot. It didn’t lock the gun up but I noted that was the maximum for me and my rig. The same shorter load garnered 1800 and 1900 fps from an Encore handgun and 16” Marlin lever rifle! Near .444 Marlin performance from so much less powder.

My Super Redhawk is a stock 9-1/2” except for the re-chambering. There is not much it won’t shoot through and whistle onward. I shot a big boar at a HHC gathering in the quartering away ham and the bullet was found under the skin on the front shoulder opposite side! It was deformed and nose smeared from many bones penetrated. I think it still weighed about 270 grs.?! I’m a true believer. Recoil is very snappy and it makes a huge fireball, but it’s a real tool for handgun hunting.
