The variables are staggering and I'm trying to stick with what I have experience using. The faster burning powders will yield about 7000PSI while the slower burning powders can get lower than 5000PSI. I may try some loads with IMR PB which is number 25 in a list of 134 common powders available according to the Lyman 5th ed. reloading book (burn rate fastest to slowest).
My initial inclination was that the thin spot should be of no concern 22" down the bore with the exception of the susceptibility to dents.


Stay in that 5,000 -7,000 zone and you will be OK, provided the gun is sound.
