I just started loading the .45 acp and wonder if I need to buy a taper crimp die to make sure they chamber correctly. I was reading on the Lee Precision site and it implied that taper crimping is almost a must for autoloaders. If it matters, I am shooting a government model colt .45 1911.

Also, what are the advantages and/or disadvantages to shooting cast bullets in the .45. I think it may be cheaper but past that I have to plead ignorance.

thanks,
