Got my first build "done", but a few things remain, namely some magazine work. This is off a model 12 stainless cf sa with blind magazine, and everything works smoothly BUT when I tried to load the magazine to cycle through rather than just feed single rounds manually the rounds would not feed. The bolt cathces the rim at first, then after the bullet tip hits the feed ramp or shortly after the bolt slips over the top of the cartridge and slides forward with no bullet. What did I do wrong or what must I change to make the magazine functional on this gun? Also let me know if you need more info (or even pics) so we can get this thing functional! Thanks,
Luke
