That’s interesting, didn’t know ER Shaw did polygonal, thought they just did standard enfield rifling. How many grooves does it have?
I’m still waiting for someone to come out with a 1:24 twist 3 groove poly or ratchet rifling. I believe we could get a decent velocity gain when leaning on it. BHW is a 3 groove poly, but has an 1:18 twist. So far it’s showing promise, but since the bolt failure, I haven’t had time to do any shooting.
