I have started reloading .45 again after an 20+ year hiatus. I am using 230gr. Berry plated bullets with 4.5 grns. of Bullseye. The COAL of the .45 is 1.275 and I loaded mine at 1.250 as instructed by Ruger in Prescott, Az. Today at the range I had 3 FTF (failure to feed). 2 of them were my reloads and the 3rd was a Remington 230gr. round ball. I took the rounds home and measured mine and the Remington factory load. I had a variance of .002-.003 on my reloads so I decided to measure the Remingtons. MY COAL used was 1.250 and I found that the Remingtons ran from 1.248-1.260 which really surprised me!! I thought that factory loads would be much closer in tolerances. I measured some Hornady Critical Duty and they measured @1.245 and fired them. Everyone of them fed without any problems. I am wondering if anyone has run across this before and if so, please let me know and which type of ammo it is. For the present I think I am going to use 1.245 as my COAL and see how they cycle. This is for my SR 1911. I did the "plunk" test before I shot them and they all passed and I was trying to seat my bullets as close to 1.250 as possible but due to different casing lengths, it's hard to get them exact. Please advise me on any of your experiences.
