We are talking blown up guns here.

Anyway roughly how much percent of the case space under the bullet is taken up by your charge? 40 grain does not sound like underfilling.

Someone here may have some calculator software to tell you what pressures to expect from that load.

Difficult to give a persentage, but with 41gr I can still hear movement inside casing when I shake it, after I seated the projectile, so I would estimate that I would be able to go to about 44gr before starting to compress.

If I load the case to the brim is takes just a bit more than 47gr in total.
