I crimp all my cast rifle bullets, usually in the provided crimp groove, and in some cases regardless of how far you can safely seat the bullet out you can't touch the rifling. Here are some test targets I shot @ 50 yds. with a couple different Lee bullets and various powders in my Remington 770 in 30-06. All bullets were sized to 309" after powder coating and gas checked and crimped in the provided crimp groove.

My best load to date is the NOE 30 XCB 170 gr. cast bullet over 35.0 grs. of H-4198, average MV for five shots was 2297 fps. Bullet was cast from 50/50 PB/WW coated with Eastwood PC at baked at 400 degrees for 20 minutes after powder flow out begin. Bullets were water quenched right out of the toaster, gas checked and allowed to sit for two week before loading. I seated this bullet about .020 off the lands and give it a light crimp using the Lee FCD.
