Many excellent actions available in today’s market. Some use different designs. Two lug or three lug, bolt throw, method of cxcking, extractor type. Lots of questions. Some are better in dirty /dusty conditions. I’d research what the top prs shooters are using. I’ve had great luck with Surgeon,Defiance and the Impact 737R . No experience with the two you mention but I’m sure nutters will chime in with personal experience. Good luck with your build! As a side note ATRS also builds and is in your province!!
