I know of no such literature or articles on the subject. There are few absolutes in shotgun load development. In general, I have found the following to be true:
1) Slower burning powders tend to produce lower pressure than faster ones with any given payload.
2) Obviously, increasing the payload will tend to increase pressure.
3) Smaller gauges generate more pressure with a given payload weight than larger gauges. For example, a 1&5/8 oz load in a 20 gauge will generate more pressure than the same payload in a 12 gauge with the same powder.
4) Anything compressible under the shot will tend to lower pressure, whether that is a collapsible section of a wad or adding cork or felt beneath the shot.
5) Increasing velocity tends to increase pressure.
6) Fold crimps generate more pressure than roll crimps.
7) Adding buffer to a load tends to increase pressure vs the same load without buffer.
I've been told that the addition of mylar will increase pressure, but I have never verified that through pressure testing.
9) Hull and primer substitution can be a mixed bag. Pressures do not always change in the direction one would think when changing to a hotter primer or to a hull containing a hotter primer.
If I really wanted insight into TSS shotshell development, I would buy some shot from Hal Abbott, aka , and contact him during the off season. I would venture to say that he knows more about TSS load development than anyone else on the planet.
Be safe.
