Of the guns that did not require service from Ruger, many, including mine shave a thou off the bullet when chambering. This can be remedied with precise gentle stoning but I would recommend against...

There are reports of the Competition models having finicky chambers, some requiring service from Ruger.

Mine feeds all the common mid-tier stuff fine EXCEPT for CCI SV.

I go to Trail Glades Range. Best? Doubtful. You'll need to sit through a 20 minute safety course and get a range card. $15 for 4 hours at a position after that. The rifle positions don't have casing...

You're going to scallop the face into a 12 o'clocl/6 o'clock strike leaving the center unsupported, right?

If so, check the rear of the cases for pressure signs. I doubt there will be any.

Sounds like there could be a lot of interesting discussion between "Has anyone ever shimmed their bolt" and "shims for sale".
