You are telling me.

I tried to get a full tilt 270 gr TSX load in a 375 ruger to match with a reduced load shooting a 225 gr bullet. I even down loaded the 225 bullet quite a bit and never could get it to work out.

What I have surmised after talking to a few people on the web, and looking back through my notes, is if you are shooting a projectile that is 20-25% heavier, and about 20% slower, that will be close to 2" high at 100 for the lighter projectile and zeroed for the heavier projectile.

Thats just in general though and looks about right for normal calibers.

What is the weight of your solid.
