Picked up Clerke Hi Wall in 7 mag at last gun show. Condition at least 95 %. Problem exist in that the bullet is too hard to chamber and upon firing, the extractor will not lift the brass from the chamber. The gun is near new, rifling is sharp,clean. Am not knowledgeable enough to make a diagnosis on condition of chamber. Any good advice from any of you that have insight on this type of problem would be appreciated. I plan on taking it to a good "smith" in two weeks and let him make it well again but still am interested in what you think might be wrong with it. If the chamber area is eroded or damaged, will probably rechamber to 280. thanks ahead of time.
