I've used the Ranier plated hollowpoints in 9mm in my K9 with no problems whatsoever - but never tried them in .45acp.
If it were my gun and adjusting the load length didn't work, I would be happy that it runs with other hollowpoints and with SWC, and sell/give the remainder of the Rainier fodder to someone who can use them. It ain't worth fussing with the gun over. Really - why do you want to spend extra money on the plated HP's vs cast SWC?
