Not recommended

Brownells USA Does not work for 6.5 Creedmoor 24/07/2018

Bought this 30A to check bumping the shoulders of my 6.5 Creedmoor brass. Had been using a Wilson Case gage to do the job and it works well I thought this may be faster. I bumped and bumped no reading beyond the initial cal of 1.501 on the digital calipers. Each bump i got a new reading on the Wilson Case Gage. Highly disappointed with the purchase.

Definitely recommended

Brownells USA Quality 20/06/2018

I have the original Stoney Point tool and this fits and works well on .338 Lapua Magnum cases to adjust the amount of shoulder bump on cases.
