Ok so having some magazinr tube feeding issues with my 336ss Marlin 30-30.
Background
Bought the gun new 3 years ago. Hunted with it my first year ,took a deer and it sat in the safe the next couple of seasons. Main reason I didn't take it out was because it was rough and didn't always feed reliable. So last winter I watched a few you tube videos on smoothing out the action. So I took the gun apart and polished all the surfaces that rub against each other. I did very light sanding with 400 grit ,than 2000 grit .NO FILES USED, and I just shined up the pivot points mainly along with where the bolt contacts the hammers top edge. Definitely smoothed up the gun. Went to test for function and was having trouble with the rounds hanging in the magazine tube, than after cycling a few times the feed gate screw sheared . Posted here about it,got some good advice,and fixed the gate. Tryied her out again afterwords.and still had rounds hanging in the tube. Got annoyed and it has sat in my safe since.
So tonight I said well let's figure this out. Pulled it all apart again including removing the feed tubed and fallower, smoothed out the tool marks and took out a few burs where the bullets first enter the receiver from the feed tubed than polished it. Cleaned the feed tubed out and than made sure the fallower looked good. Reassmbled and figured it was going to be good and figured it was just the rough patch in the receiver catching the cartridge rims or something. Tested for function ,and Bam round hangs again just like before. It's not always the same round ,and doesn't matter how many rounds are in the tube still. After looking closer I found the round was actually being stopped by round lifter (not sure the proper name) shown in the picture. Other than that issue everything works as it should. I'm not really sure where to go from here.
I did try to push the lifter arm down with a screw driver and it seems like it is in the downward position. Could the fallower be kicking the rounds off center? I can't see how that lifter arm could shift any because it sits pretty tight in the receiver. So idk ,advice would be nice.
