I really like the Possum Hollow guides and ordered a #7 from Midway(I don't remember where I got that info). It didn't work and I returned it. I have Emailed Eric at Possum Hollow asking which is the correct one. I think it's a #44 which fits a Remy 700 "6.5-284, 6-284". Reading through the reviews on Midway and one guy said that the #13 is correct(I don't see how, chart says the #13 fits S&W I bolt). Any help is appreciated.
