Cals are 204, 222, and 22.250 - running 39bk in the 204, 50gn Projectile in the 222 (seems to shoot most of them well) and 55gn Sierra Super Roos in the 250 - all the barrels are the same length at 24".
204 @ 140m - load is 28.1gn of 2206H/7.5Rem Primer behind a 39gn Sierra Blitzking (that load is over the ADI Recommended) so don't assume it is ok in your rifle (safe so far in mine with no signs of pressure etc).
222 @ 100m - load is 20.5gn of 2206H/CCI SR Primer behind a 50gn Projectile.
22-250 @ 100m - 34.5gn of 2206H/CCI LR Primer behind a 55gn Sierra Super Roo Projectile
Disclaimer:- none of the loads above are meant to be a recommendation for anyone else to use in their particular firearms, they are safe in my particular firearms and I would highly recommend starting from the min recommended in your particular reloading manual and working up carefully keeping an eye out for any potential pressure issues.
