I have a new cz75bd, and trying to sort ammo for it.
I am using cast bullets sized to .357. The oal after bullet is seated is 1.095, and chambered round is not contacting the lands, with a max length of 1.105 touching the lands, so all seems well there.
When I plunk test the round, it sometimes sits a few thou proud, but with a little gentle push seats easily. When I invert the barrel sometimes the round will not fall out, and I have to use my thumbnail to extract it. I can not spin the case in the chamber with my fingers, but with very light assistance with pliers i can spin the case.
What I see is the throat diameter is a little too tight for the bullet. After the spinning of the cartridge, the bullet is making contact with throat for about 0.030''of its length, and now measures 0.356 to 0.3565'' in that area.
My question is, will that cause lead scraping/fouling, and eventual fail to chamber?
I guess I need to try it and see, but does anyone have experience with this?
