Good for you Lone Wolf!

Now that your decision is in, I like to leave one more tip some friends of mine use back when we were shooting on a 22LR team.
I didn't think of in at first - as we were discussing CF single shots and hunting rifles.
I remember this when Bronko mentioned lapping rifle barrels.
Several other members on our team were (I'm not going to call'em collectors) - They were "gatherers" of old used 22LRs.
They had their competition rifles,
but we couldn't travel together anywhere that they weren't stopping at every pawn and gun shop buying old 22LRs.
Old Rem and Win Comp rifles, 22LR military trainers, oh list goes on and on.

The very first thing they would do to these old used rifles was to clean and polish the throat.
22LR ammo is dirty and is notorious for collecting this "soot" in a ring at the throat of the barrel.
They would brush, clean, polish the throat over and over repeatedly to remove this "soot" ring.
They used Brownell's Bore Bright polish - More a polish that a lapping compound,
But they used it like a lapping to completely remove this ring before shooting them.

So there, we covered the 22LRs just in case it's of interest for others reading.
I haven't had occasion to used it, but they convinced me of this tip.
