Went upstairs to my indoor range we are getting our first fall storm rain & wind that’s the PNW.Tried a different scope on the PC77 I don’t think it made any difference. Mike my PC has a 16 inch barrel and I have no idea where I got it . Built this one a long time ago. Good shooting Bryan ! Tucannon PC77 CarbCP 3-9X32.177 CPWCStanding/ Offhand194/200 1X
