You will want to check primers with that 16 gr 2400 load. That is a start load and depending on your brass and the depth of the rim cut in your chamber, it may be light enough to back primers out. If so, a bump up to 17 - 17.5 grs will serve you well. Lyman 49 lists 2400 range as 16 - 23 grs with that bullet. Your bullets are sized to .311 which is probably a good choice but you should slug the barrel to get an exact diameter. 22 BN is pretty hard for such a light load, albeit a fairly fast burner, so it may not obturate (expand in the bore) well. I prefer the slower powders with cast in a bottleneck cartridge but you will decide what works for you.

Enjoy
