As Arley has stated, they may be a bit undersized. For what it’s worth, my opinion is there are too many properly sized and heavily jacketed 454/460 designed bullets for you (us) to fool with .45 ACP projectiles at magnum velocities. Loading at such velocities will likely at the very least make getting a good bite (crimp) without bullet deformation to hold the thinner skinned slick sided ACP projectile in place more trouble than it’s worth. A Lee Factory Crimp die can only do so much.
That’s not to say that I may not tinker around with some of these in .45 Colt brass at standard .45 Colt velocities. They may shoot great and be a lot less of a headache to keep at desired length.
HS6/Accurate #5 or CFE Pistol/Win Auto Comp will likely get the load density up to reasonable levels and deliver enough “Umph” to allow you to know you’ve fired one off.
Please post your results if you decide to pursue using these.
As always, YMMV. Be Careful. No distractions.
