Got her out to the range today and with a 375296/273gr FN GC over 32 gr of IMR 3031 in Starline long cases and Fed LRP's managed a 1" 3 shot group at 100 yards benched with a 4x Leupold.Velocity unknown at this time but it should relax moose and mule deer just fine if I get my draws.They were sized .379 as that as small a sizer as I had taking them down from .381 The groove is cut .376 1-16" but these big bullets feed fine so I guess I'm ok there.Formerly a early 1950's 30-30 half mag carbine 20" not a waffle top but pre -crossbolt safety.
