FYI:

OAL in testing using factory magazines. We recommend if reloading to start between 1.145-1.155. This stacks well in the tube but if you wish to push out longer than do so cautiously as different brands of tubes. Internal sizes can vary, too long will cash slow bullet rising.

Crimp is very important to magazine feeding. Be sure to keep at factory specs. It’s easy to measure we use Winchester white box that comes in .374-.376. Incorrect large crimp will case slow bullet rise and stiff loading.
