Just because I do it, does not mean you have to do it, but it does work.

For the plunk test, please take the barrel out of the gun first.

Yeah, I used to crimp to 463 with wonderful results.
Then I backed off to 465 with wonderful results
Now I'm backed off to 468 with wonderful results.
The brass lasts a little longer at the larger diameter.

Fun fact....
I used to load ammo for the guy that started the original bullseye forum.
