But don't just slap that in your gun. You need to measure what the contact to lands length is to make sure what is safe for your chamber.
Of course, I measured my chamber with the cleaning rod method and got a little longer than 2.260. Im going to try the light neck tension on a fired case method next to double check my work. I tested a dummy round at 2.260 with no chamber or ejection issues. Thank you for the input!
