Good idea just don’t get that collar stuck in there, remember if it can happen it will happen.

Yep. Remember him doing that well. I found several in different calibers in the basement while clearing out the house last year…unfortunately for none of the guns & ammo I shoot. Sadly they went in the trash. Several for; 6BR, 6PPC, & 22PPC (Or BR…)

Sinclair know’s what they are doing, Boyd. Their chamber length gauges are made from 12L14. It’s soft enough to cause zero damage to the chamber/throat area.

Handy homemade tip. I use the Sinclair chamber-length gauges. They work great. Most of my match chambers are .010 longer then SAMI spec. Hunting guns can up to .030. Saves on trimming.

Good tip. It is not often that I see something like this that is entirely new to me, but this is. I will have to give it a try. I would never use a steel plug for this, no matter who sells it, because if there is a miscalculation, the chamber throat can be damaged. This method uses a case that will fit the chamber, and the clearance is established when the case’s neck is cut with an abrasive wheel, the width of the cut automatically guarantees some clearance.
