See now the two magazine you listed would be a good buy even at $10 each.
I want to find more information like this just about the 45 LC. As I said these hot rounds are only going to be used every so often keep skill up using heavy rounds with high recoil and if I ever need them for a hog.
Mostly going to shoot for fun the Lee 452 255 gr that I just received it does cast more to 260 gr but that's also fine. I also feel that the 260 gr would be a nice light SD round on hogs.
