Yes I have noticed load manuels vary allot more on wadcutter loads than on other loads. I assumed it was because they were just going for low pressure target loads and weren't loading them up to full pressure. Which I am fine with for the most part.
Here's the rub, my wife is small and very recoil sensitive. She think 9mm in a full size handgun recoils too much. So I was looking at loading up 38 wadcutter for her personal defense. Lyman's data came in useful as it was more potent than most.
