The 22-204 is a 222 Rem Mag Improved, 30 degree shoulder, longer body and slightly straightened body.

If you want to build even longer on a small boltface you can use 5.6x50 Mag brass, it is 3mm longer than the 222 Rem Mag. I shoot a combo gun using the Rimmed version of the 5.6x50 Mag. You do start to run into mag length problems.

If your looking at a going with a small boltfaced gun don't overlook the 22 Valkyrie

Or if a mini-action, 527, mini-Howa, mini-mauser the 22 lbc (22-6.5 Grendle) doner actions can be found with a 7.62x39 boltface.

If a standard boltface, why limit yourself to the 22-250 if you want to go fast with heavies, there is the 22-243, 22 Creed, 224 TTH and a plethora of others

And then there is the 22 WSSM
