I do not know what I am doing wrong! I have reloaded my 500 NE 3 inch bullets for almost 2 years now. This is the first time I have reloaded Woodleigh .510 RN SN in 570 Grain. My previous Swift A Frames gave me no problem. Please look at the picture...The bullet is in the required 3.75 COAL yet a bulge is being created at the top of the full case as you can see...please provide me with advice as I am ruining bullets which are not cheap.
Thanks!!!
Thanks!!!
