I was going to load up some rounds for my dad's 45 long colt. I had some IMR 4227 around and found a load of 17 grains for it. I am using a cast 250 gr. RNFP bullet. I loaded a couple up and the powder wasn't burning completely. I have a large pistol primer in it. Any recommendations for this load or a different powder you have had luck with.
Thanks in advance
