don't get carried away, rather small changes and minimal changes,
can result in very noticeable results,
and its very easy to irreparably damage parts.

always use safety glasses, and remember the cartridge length and bullet, nose & geometry
and lubrication has a major effect in how the cartridge feeds reliably or not
changes in the magazines and magazine follower can cause or cure issues,

you might think were barrel feed ramp related
in many cases a simple pencil eraser dipped in extra fine jewelers rouge ,
and a few seconds rubbing can make the desired results.

having good lighting and a large magnifying glass and a small padded vise can be very helpful






watch the videos but be aware some of these guys are removing FAR TOO MUCH metal and screwing up parts

having a good padded, angle vise helps when working on small parts and they don't cost much
