[QUOTE="swampratt, post: 3788429, member: 15054"] [USER=15840]@Sgt Dog[/USER] when I am curious on something I set out to satisfy my curiosity. I have shot 170gr cast gas checked 357 magnum loads with 2400 powder to 1370 fps from my German 6" revolver. I did not crimp and marked 1 chamber and left that bullet in there for 10 rounds of firing and then removed it and measured for setback and there was none. If you do get set back a light crimp will probably help that out. I think factory loaded ammo has a crimp because rough handling and the possibility of any set back may really bring pressures up and may make the ammo not chamber at all in some weapons. (not go up the feed ramp smoothly) I loaded some bullets into some cases and then drilled a hole into the bullet and ran a wire through the bullet so I can pull the bullet out of the case. Chucked the case in a vise. Had a small scale rigged up pulling on the wire to check Bullet pull in PSI. I had a 357 loaded with a powder coated bullet that NO crimp and the bullet would not come out of the case. Wire sliced through the bullet. It was the kind of wire you hang a picture on the wall with the stranded stuff. [/QUOTE]
