Hi, Looking for some input on a Interarms Mark X in 7 rem mag. Rifle was made in 1976 and I picked it up a while back, just getting it set up now. The rifle appeared to be unfired and cosmeticly perfect condition. First problem was an epoxied front action screw, from the factory best I can tell. Sucked getting that out. Replaced screw , one issue solved. Feed rails razor sharp, ripping up brass real bad. So i stoned and smoothed sharp corners. Rifle had a chipped extractor and would not eject shells. So I replaced extractor. Took a lot of trial and error to fit a new standard ejector for a magnum case , but now it feeds real smooth and ejects most of the time.
The problem now seems to be that a 7 rem mag case is larger than the right side bolt lug raceway on rifle. Cases want to jam or hesitate sometimes because they can not cleanly get out, Extractor and ejector work great when compared to other 98s and model 70s i have. It looks like metal needs to be removed from corner were upper corner of lug raceway meets ejection cut on reciever. For comparison an 06 size case would not have this problem because the case size is smaller then the raceway and clears action.
Looking for some input on this and rifle is also a little hard to cock , similar to a old savage 110.
