Well just thought I'd let you guys know that I got 5239 fps a couple weeks ago shooting 30-grainers with my 224 McDonald, a wildcat cartridge based on an improved 6BR case necked down to 224. (This case is very similar to a 22 Dasher.) The bullet used is the 30gr Berger. (The 40s run fast too — about 4800 fps.) The rig is a Rem 700 with a 30″ Hart barrel. Below is the case before and after forming. As you can see it has a 40° shoulder and far more case capacity than a 22 BR (a 22 Dasher case holds about 41.0 grains H20). My most accurate loads are with 50-52gr bullets, with bugholes the norm at 4200 fps.
