No4 Bolt Advice

[RobD]

Two different problems, and I'm sure there are many ways of approaching them. Here's my 5c:
- The bolt sticking when moving back and forth: is this the bolt head in its guide that's sticking, or the bolt body? Sort this out by trying the action with the bolt head removed; if still unclear, I'd colour the whole surface of the bolt a felt tip permanent marker in a dark colour e.g. blue, move the bolt in and out several times to get it to stick, and see where the blue has worn off.
-If primary extraction [i.e. lifting the bolt] is too hard this may indicate your chamber is a bit rough or pitted. A peep with a $10 bore scope may confirm this. If so, there are many ways to polish the chamber. One method is to spin in the chamber a fired case smeared with metal polish - see Polishing A Chamber With A Fired Case?
If doing this method, I suggest trim the fired case at neck before using.
