OK I found the pictures of a MK-85 outing...
The picture says 100 grains of T7 but my notes say 110 grains.
There is also no doubt in my mind that if I used a lighter bullet or back the powder back down - this would not be an issue... but even then the situation always exists because you just never know...
But here are the pics....
Now I also want you to know that this same load with a #11 cap works great and while the cap is in pieces it is all inside the cavity of the hammer.
