I probably use the first ones around the time you started the company in my .45 Blackhawk. I loved them. I may have even spoke to you on the phone about that time. I have more test data to post and am currently involved in another series of tests using jacketed bullets in the 45-70s and .450. When I first did the test with the 460gr I shot them 1840fps. Huge media damage but less penetration. I slowed them down to 1700 or so in the .450 and they out penetrated the .375 solids handily. I figured I could slow them a bit more and penetrate farther but trajectory was a concern since I used the same loads for hunting deer. Took a whitetail doe at 184 yards with one of hte 460grs. I shot these 15' from the muzzle. The velocity around 1700 seemed to be the best of both worlds. The load with H335 averaged 1728fps and consistently shot groups like the one I posted. I load the 255gr .429 in .44 Special cases over a stiff charge of U-Clays and from my scoped 441T Taurus target model shoot 1.5" groups at 100 yards. I have been wondering how Kelly is doing of late. The data I worked up and sent him was with Benchmark so if you wonder where that pressure data came from now you know. reflex264
