Bullet slides down in 45acp brass?
I have loaded 1200 45 acps with no problems using cast 230 gr and some FMJ 185 Hps. I ordered 100 Rainer plated bullets 200 gr RN from Midway. I had two that didn’t load tight.
One of them I could pull the bullet out of the case with my fingers. Even with a excessive crimp from my lee factory crimp die it still could easily be pushed down into the brass. The plated bullets measure between .451 and .452 with a micrometer. The brass is RP that the bullets are not fitting.
I knew something was different because my press had very little resistance during each step. I thought that was weird so i pushed on the bullet and it slide down in the case! These rounds do not touch the factory crimp sizer.
I am using Lee dies. Any suggestions?
Bullet slides down in 45acp
I would check the expander die I am make sure one of the adjustments had not changed I would also take a look at the case itself I do not know how many times they have been shot but if you are loading close to the maximum charge you can definitely get some stretching that you may not be aware of I would also try once fired case at the original setting and if I had access to it I would find a brand-new case and try it make your own judgments and be careful particularly if these are going to some kind of semi-auto or automatic a deeply seated boolit can change pressures greatly causing bulgeding Casas and in extreme conditions explodeding firearm
hope this help
