Maybe you should get one and find out..
I'm shooting the 20x47 Lapua which holds about 1-2 gr. less water, so a little less volume than a standard 22-250 and I'm also using the 22-250 load data. On max loads I can get a few grains more in the 20x47 L and have way more vel. using the same weight bullet... If you want numbers just say the word and I'll go look them up in my log.......
