From what I understand, 21.5 of H110 was what Cast Performance recommends. I do not know if that is low end or not. I figured it was as I've seen H110 loads up to 23 grains for the 300 grainers. It was even suggested by another to start at 22, but I figured I'd go with what Cast Performance told me. I defnitely don't want to go below the low end considering it's H110.
I've always used WLP primers and I figured that since it says for standard or magnum loads on the box, then they would work fine. I also understand that Winchester primers run a little hotter than others.
And to be honest, I wasn't sure if this was even
enough crimp. The factory crimp on some of 454's was
much more than this. I was surprised when you guys said that it was too much. :lol:
My concern was that the crimp groove on these pills is HUGE. I can't help but think that the crimp is only halfway into the crimp groove and was concerned that I might still get some bullet pull (maybe they would if they were loaded hotter, but I figured this is a fairly stout load and didn't want to take the chance).
I've had this Redding for a lot of years and it does make a nice roll crimp. I just turned it down a bit to get the same kind of crimp I've seen on factory 454's. That might have been a mistake.
I use the Lee crimp dies on my Dillon for 45 ACP.
These will be getting shot in a Ruger Redhawk. Now I'm concerned with shooting them at all with the talk of increased pressure. Maybe I outta pull em' and start over.
Man, this is a lot different than loading up a few hundred rounds of 9mm or 45ACP on the Dillon. :shock:
