.22 br

Thanks to Padom for providing some numbers, I did some quick math based John Barsness’s rules regarding capacity and pressure for a .22BR vs. Hogdon’s .22 ARC data for Ramshot Big Game and a 85.5 Berger.
Found a half decent node at 32.1 grains for 2,973fps out of a 24” barrel (Bartlein 1:7”, 5R, suppressed).
