JB suggested I ask here if anyone could run a program specifically for the 7X33 cartridge made for old Sako L461 rifles. The capacity of the case is 21.4 grains of water, case length 1.32 inches and the bullet weighs 85 grains. Bullet diameter is .285 inches. The bolt face and cartridge rear dimensions are the same as 9mm Luger. Primer is large rifle.

Here it is with the bullet on the left and a 222 Magnum on the right.

Thanks for any help on this...

I can't, but that is a good looking cartridge. Kind of like the 5.7x28.

I only have a QL version that's a few years old. It didn't have the 85 gr bullet you described, just the 79 gr. Hope that helps.
