CraigC,
My Enfield shoots pretty good, but I can't shoot irons worth a darn on the No.1 Mk3 sights. I can't really shoot those style, a v with a front post, very well these days. The sights float on me. Now something like an A2 peep or Williams I can shoot really well.
I think they make a Williams for the No.1 Mk3, but like you, I'd like to have a sporterized Enfield.
I know one thing, I'll be taking my Lithgow to the woods with me this year more than I have in the past.
I am loading up some .312, 174 grain Hornady round nose bullets tonight with W760, BLC-2, and IMR 4350 for load testing this weekend. Got them all ready to put powder in tonight. I am hoping the W760 works out because I have a couple .lbs of it, but nothing to that it will shot in but the Enfiled. Crossing my fingers that it does shoot well with the 174 grain round nose. I am looking to get 2400 fps from it.
