One thing I never liked about the 8mm RM was that the bullets are seated way down the neck to reduce the O. A. L. Some years ago that led to a discuss with a gun nut buddy of mine that went along the lines that you could use shorter brass, seat the bullets at the base of the neck and get very close to the same fps out of it. Heated discussion leads to a bet. He say you can't get within 300 fps and I say you can.
Congrats, you were AHEAD of the curve. I have been too on a couple of other things.
OTOH, I have found that compressed loads aren't a handicap. I was shooting compressed loads in 270 W & 06 long before I got my 8 RM.
**Note** I know you can have too much compression and the bullet will get pushed back out ---> not good.
