Tightening Savage BP

[ET]

With so many different BP designs out there I’m just looking at the Sav. Concept and what I feel it needs to function at it’s best. Here I want to look at the mating surface that butts up to the barrel. So, what is the purpose of the mating surface on the BP? Simply to retain the bore pressure in the barrel. But in order to carry out it’s function it’s needs to be properly tightened. Hand tightening alone doesn’t cut it IMO.
So, what happens when BP is not properly tightened? Then the bore pressure is going to try to make a pathway to bypass the pressure boundary seal by hot gas cutting. Keep in mind there are fine carbon particles suspended in the hot gas. So, what happens when the particles reach the BP threads? I’ll let the reader come to their own conclusion.

The pictures below especially where gas cutting is seen is not intended to cry “The Sky is Falling” because I really don’t know what level of gas cutting is detrimental. The bottom picture shows the result when proper BP tightening is applied. Hopefully some info is useful to a 10ML-II owner.

So what torque do you recommend?

Sorry' I don't know what the equivalent torque valve would be to the medium whack I use on the ratchet handle.
One other point I forgot to mention because it's just a given to me is to check the mating surface on the barrel for cleanliness.
You want clean metal surfaces for best contact for a good seal.
