Ruger mk III question

Shooting this gun today, its about 6 months old, stock MK III, I keep getting failure to feed jams. It looks like the bolt is coming forward before the fired casing can fully eject. The next round is feeding fine the bolt is just catching up on the spent round. About half the time the spent casing will end up behind the new round and gas tube.
any ideas? recommendations?

First thing I'd do is tear down the magazine; lightly lubricate the inside, spring follower with Breakfree, then wipe dry. If cleaning and lubing the magazine doesn't do the trick, then I'd use a buffing wheel on a Dremel tool (without any compound) and polish the feed ramp.

What ammo were you using?
Were all the problems with the same magazine?

Check this link...It's about the MK II but may help.

oil and clean....

Ditto to the above, but I've found that some .22 ammo just will not work well in different guns. You may need to find the ones that work well in your gun.
Any .22 round that don't do play well in any of my semi autos does fine in my bolt guns. so none is wasted.

Concur with the above.

Sounds like low-powered ammo.

Shoot some high velocity loads after cleaning and lubricating it. Try other mags, if that fails.

If it was jamming mid magazine all the time the spring may be weakening when not in full compression.
