Lyman bullet styling elements "Wandering around". Nicely put. Stealing for further use and enjoyment.
Two editions of 454/452-424 at my house, as different as can be but within 1-2 grains of each other weight-wise (about 252 or so). In my 45 Colts, loaded in same brass/primers/powder weights the two styles are indistinguishable in grouping & patterning. Dunno if that is testimony to my skill set (that I can't shoot well enough to tell the difference....) or what, but that was the verdict in the Bishawk and the Uberti. I have stopped using the 1-cavity Ideal tool, and use the 2-banger Lyman marked as "452424". In 92/6/2 they fall out at a fat .454", and clean up in a .454" H&I die. These were a bit more work to run through a .452" die, but there is still PLENTY of lube and crimp groove left. These were the editions run through the PC 625 the other day, and they rang the dinger plate with some authority, even at or under 800 FPS. Size matters, as does weight. 5/8 oz of metal almost 1/2" diameter at 2.67 football fields per second will spoil yer afternoon right proper.
#454424 is still a short, squatty-looking thing.
