I,ve read a lot about the feed problems for the old .22 mag pistol by AMT.And so having purchased one recently I bought some Win Super-X ammo, some CCI and some Win Dyna point. I cleaned the rails, barrel, etc. lubed it all and Yes! it feeds badly, jams, does not return to battery, ammo jams while loading. I took it apart and see that where the barrel throat and feed ramp are welded up to each other there is about a 1mm alignment difference. There's a 1mm wall the next round has to push past. Suggestions ? Gunsmith work to smooth the junction of the two or something I can attempt ? Barrels are not too common and I presume there should be a smooth ramp to barrel inlet as with larger caliber guns. Some photos included. Phosco
