Default hand lapping

I have a tikka t3 7mm l/s , and have put about 200 shots through it if not more. (maybe even 300). Anyways, would i see any improvement if i were to get the barrel hand lapped now? Or is that basically a strictly brand new barrel type of deal?

My local gunsmith does it for only 35 bucks, so i figure if it will help group by even .001 inches, it would probably be worth it.

It can still help. But clean that bore really well first. It needs to be totally spotless, and de-coppered.

If it ain't broken, don't try to fix it.

My local gunsmith does it for only 35 bucks
The question is, does he do it correctly for $35?

You can easily ruin a barrel hand lapping. I think its wise to have a bore scope to see your progress. I tried hand lapping a throat of a gun that had heat cracks, and over did it. I didn't know what I was doing at the time. I wasn't too upset, because the heat cracks in the throat area, but had to have the gun rereamed, and everything reset and lost over 1.5" of barrel. I ended up selling the gun. Took a big loss.
