That is why I was asking. 1.235 is too long for the Lee tumble lube design. It will jam the lead shoulder into the rifling and prevent the gun from properly going into battery. OAL of 1.185" is better. I couldn't get 1.185" to feed in my gun (too short), and got rid of that mold.
Basically, in a LSW design, you want about 0.030" showing of lead shoulder above the case rim.
The Lee design really has a squat nose, which leads to the shorter OAL length. I had people arguing with me that a 200 gr LSWC should be loaded to 1.245", but they weren't taking into account the nose profile.
For example, the Lyman 200 gr is closer to the classic H&G design. I took this picture illustrate the difference is design:
