Maybe you hit the nail right on the head. That's the problem, reliability!Perhaps there is a reason data is not readily available (like a fer-crap bullet that's difficult at best to get reliable function?).
Have you contacted the bullet manufacturer for load data?
What OAL do you use?I'm a cowboy shooter and have plenty of this style bullet, started combat shooting and didn't want to buy more bullets for the 45 ACP unless I had to, found some posts that people have tried and I tried it, did several of different loads with clays before I settled on one that does me just right for combat shooting and plinking, my load is 3.9 grains of Clays with the 200 grain RNFP bullet. They all cycle good in all of my 1911's with no problems.
All for now JD Trampas
