I have a 93r in 17hmr that every since I have had it I have to press up on mag to get it to cycle a round, it hangs or jams if I dont press up. If I press up on bottom of mag its smooth as butter loading. Bought some new mags still hangs with new mags. Is there any known fix for this? Is it common in other 93r's? If I try to force it, it dents the case and jams.
