Well vel alone is also just a guide. Vel varies from pistol to pistol, bbl length to bbl length, so trying to "guess" pressures by vel will get you into pressure trouble very quickly (ie, trying to get "book" vel in a G26
). If the loads in farnorth's pistol are not showing pressure issues, then they are "safe" in his pistol.
