We’ve all seen the pressure curve charts and know the pressures begin to drop off drastically after exiting the chamber. Personally, I pay closer attention to the thickness at the juncture of the chamber and the beginning of the cone..

Wall thickness is great, with .130 in both barrels at the end of the chamber, .121 at the end of each forcing cone. The minimum wall thickness is .038 and .036, 5” from the muzzle....
I do not have access to DGJ since they stopped offering it at "book store" outlets. If someone could scan the article and and send it to me I would appreciate it.
Thanks
