S&W just returned my M63-4. I sent it in because there was a notch in the crown at the 1 o'clock position. They replaced the entire barrel! I thought they'd just recrown it. Total turnaround time was less than 6 weeks. Impressive. This is a J-Frame 22LR revolver with a 5-inch barrel. I sent it in because the groupings weren't as consistent as I'd like and the notch bothered me every time I looked at it. Do you think I need to re-sight the revolver and go through the trial and error of using different 22LR brands? FWIW, the old barrel used to love Remington Thunderbolts. Go figure. Thanks in advance.
Is zeroing necessary after barrel replacement on M63-4?

Start with your old/current ammo. You never know, you might get lucky.
But a bbl swap is like removing a scope or changing the sights, etc. It's almost certainly gonna change the point-of-impact, IMO.

I finally got to the range today. All y'all were correct: zeroing in was ABSOLUTELY necessary. I shot iron sites off sand-bag rests at 25 yards. I have 80 year-old eyes, but the accuracy remains around 2 inches spread which I think is pretty good.
The elevation was initially high about 4 inches with windage about 2 inches too far to the left. Eventually I was able to zero it in, but I just about reached the limits of the elevation.
This new barrel HATES Remington Thunderbirds but is in love with CCI Mini-Mag High Velocity 40 gr ammo. The old barrel liked Mini-Mags but lusted after the Thunderbirds. The new barrel was not too happy with Standard Velocity ammo, which surprised me. Stingers were reasonable (maybe 3 inches spread) and as expected shot a bit low. Thanks to all for your input. I plan to do more range work with this revolver. To me it is an excellent example of a scaled down version of an M17 and makes a great trail gun: not to heavy but accurate enough.
