new chiappa in .45 colt with feed problems. shot 50 rds originally with no problems, now having feed problems. pull down on lever [with force, no babying] but lever will not go up to feed a round. was able to fire a few rounds through her this past weekend, but in general will not feed easily. extractor works fine when i can get it to load. cleaned gun thoroughly, with no change and will not feed snap caps either. any and all help will be appreciated !!!!!!!!!!!!!!
