jmorris makes such neat stuff!!!
I've seen no difference in accuracy between the 2. I do see slightly lower velocity out of the SP, 25-30fps. I mainly shoot the LP but keep the SP separate for cases when I'm low or out of LP. If you shoot 9mm or other caliber that use the SP it makes thing simpler on maintaining inventory levels. And you don't have to change your press over if you press prime. If your loading on a AP it's crucial that you keep the brass sorted. They can sure break you work flow when one slips through.
I have had better feeding of a wheel gun with the small primer 45ACP versions.I ask because I've hundreds of SPEER, BLAZER, and Speer-made (dot) FEDERAL (dot) 45 Auto cases. We endlessly discuss if it matters but I don't recall if anybody found an advantage to using small primer 45 Auto. In my own comparison of BLAZER small primer against (dot) FEDERAL (dot) large primer cases with the appropriate CCI primers, but all else being the same, my reloads showed no discernible difference in accuracy. Unless there is some advantage to using small primer cases, they are going into the recycle bucket.
large primers are smashed trying to fit into small primer pockets.
Maybe, we could get every one to only use small primers in .45ACP. That would be the ideal solution to this.
