Feeding Issues

Hi guys, hoping someone with a bit of knowledge can shed some light. I have recently acquired a Sportco Mod 93S which is a box magazine fed pump action .22. Issue is it does not load properly ie bullet is halfway into chamber and don't have enough cramming (I think) action to get it the rest of the way in the chamber. To even single feed(which is bloody tricky/fiddle) it feels quite right.
I've been told I need to adjust the magazine lips to have the bullet sitting higher/lower so that it can feed properly...tried that seemed to make no difference.
Thinking I need to give the chamber a clean/polish... Does the trigger mechanism come out as one if I drift the pins out....??
Hoping I do that it'll give me better access to enable cleaning...??

Any ideas tips info gratefully appreciated.

Thanks in advance.

.22 long rifle has a lot of primer to propellant. The primer residue accumulates at the front of the chamber and can get bad enough for what you have described. This is why Otis tell you to pull their cable, with solvent soaked round patch, till you feel resistance and then twist it several times before pulling the patch through the barrel. Centrefires also build up primer residue but do so at a slower rate. A phosphor bronze brush can also remove the fouling.
