col still 1.566"? air temp the same as last time?
some powders reach a "flat spot" as you climb the load development ladder. you are above stock pressures anyway, so you might want to stop there with that powder instead of increasing the charge again to get the higher velocity.
you may be getting a lot of carbon buildup in the cylinders from all that "slow" shooting. I don't think the cases are sticking due to overly high pressures. my "ruger only" loads eject with no problems with those loads being about twice the pressure max for the 45 colt cartridge.
