Would you still tweak?

so i have a SS M77/22 lr that i placed into a factory walnut stock a few years back and while it has always shot decent to good it was know to produce what i refer to as split groups. 3 shots touching at point of aim and then 2 shots touching just to the right of that group. i would get this alot. well anyway i finaly decided to bed the action and install pillars, which i did recently. so far after several outings it is shooting very consistant and i'm happy with the results. However two things i have noticed while going through the rifle over time, first off the crown could really use a nice recrowning. the second item is the bolt face just adjacent to the firing pin hole seems pitted.
everything tells me that i should have that cleaned up but it is shooting how i wanted it to now. do i go for broke or just stop looking at the two items until it stops shooting well.

I'm from the "If it ain't broke don't risk fixin' it" school of thought. You could have nemo, que or CPC rechamber & recrown it, but then it may like a different kind of ammo, & you'll probably have to re-bed and or re-tune the barrel channel area.

IMO, if it's not broke, don't fix it.

If you're happy with the accuracy, then why risk decreasing the accuracy?

Of course, I'm a tinkerer(er?) so I rarely take my own advice on the subject.

Despite the visual problems, I guess I'm in the same line as 1FJEF, if it's shooting well, then don't fix it. As soon as it's no longer shooting well, then I'd address those issues.

Fwiw any work properly done will not negatively affect accuracy or ammo preference. A simple recrown or true up of the bolt face should only make it shoot better.

Tuning is rarely a bad thing, but it won't correct for mediocre ammo.

What are you shooting in your 77/22?

i'm shooting mostly miini mags out of it. i plan on measuring the bolt face depth this weekend and then use a rim thickness gauge to sort some ammo and see what difference it makes if any. i do understand that if things like the crown and bolt face are done correctly they should never lesson the performance of a particular rifle. but at the same time i am always worried that murpheys law will some how come into play more than likely though once i get some extra cash set to the side i will send the barreled action off to have all of that addressed. right now though i'm just pleased i didn't ruin the rifle bedding it. the tree rats will not be safe from my son this fall if he does his part.
i still plan on posting a picture of the bolt face and crown this weekend as soon as i get a little time.

Half of the battle with fine tuning anything is knowing when to stop.

Here's a peak at the pillars and bedding, a special thanks to Thieskell for the pillars.
This was my first bedding job and while it may not look perfect, the results were more than I could have hoped for.

I'll get the photo resized for use here, sorry about that.
