I have 2 barrels with bolts from the same supplier. Both are type II bolts with type I chambers. I didn't realize the problem until I started getting head seperations. One is a 6mm & the other a 6.5. I have had to be careful to only bump the shoulders back by 0.003" when I resize the brass.
Once I go through this lot of brass, I'll be changing to a type I bolt on the 6, but the 6.5 will require removing of the barrel extension and machining the interface since I would like to keep the stronger designed bolt on it. I'll also need to plug and relocate the gas port since it will need to be indexed ~60?.
