Mac,
That's scary!
The brass "just ahead of the rim" is the solid head section of the case, and any sign of bulging there is an indication of VERY high pressure even when you're dealing with bolt action strength.
Bulging of the case just forward of the rim in a double rifle is totally out of the question!

The 240 H&H flanged is almost imposible to find componant brass for! I passed up a very clean H&H double rifle a few years ago because of the difficulty of finding, or makeing brass.
I have never attempted to make cases for that cartridge, but the dimensions that I have for it suggest that it would not be all that difficult to do.
Maybe the dimensions I have are incorrect.
What base diameter measurement do you have for the .240 Flanged?
