Description:

Sinclair Bump Gage Inserts are used to measure the amount of shoulder bump when setting up full length sizing dies. Our Bump Gages install in either of our comparator bodies and are machined to fit particular shoulder angles of cartridges. Rather than measuring to the datum line, these gages indicate off of the shoulder of the case to get a better, more easily assessable measurement of how much you are actually sizing your cases. We usually recommend between .001" to .002" bump for bolt action rifles and between .003" and .005" for AR-15 type rifles. Also a useful tool for keeping your brass and loaded ammunition separated if you have multiple rifles chambered for the same cartridge and checking loaded ammunition.

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.
