No, the first IBI barrel with the EPS chamber didn't even have a feed ramp cut and it fed better than this one. After having an actual Winchester 52D I never dreamed the bolt would be as hard as it is to close. It's a PITA for now but I like the results I'm getting.
Okay, that's what I've heard consistently with those running Eley EPS. I have the option right now to take a 45minute detour and have them ream my current Win52D barrel with Eley EPS... making it an interesting hybrid. No idea how it will shoot, but I am sure hoping it'll feed better!
