I recently bought a Ruger American Rimfire .22LR for my 10-year-old son to learn on. Unfortunately, we experience feed jams roughly 1 in 5 cycles, with the sharp leading edge of the chamber cutting into the bottom edge of the bullet as it angles in from the magazine. I've tried two different mags and two types of ammunition. I'll try other ammo still (if I can freakin' find any), but I'm also thinking about taking my Dremel and putting a very slight chamfer on the bottom edge of the chamber, just enough to avoid the sharp edge from digging into bullets as they attempt to load. Does anybody recommend (or advise against) this?
BTW, I'm not new to bolt-action rifles, and I own two other Ruger American bolts as well---one in .22WMR and one in .243---so I'm pretty confident it's not shooter error. I'm not one to soft-stroke the action; this thing just seems to do a good job of snagging bullets as they load. I'm surprised the chamber has no type of lead ramp.
