Dear Ben,
I have a 6.5, 10, and 14 [.22]. All iron saddle sights. I totally agree with Curtis, the ten is funnest. Except for maybe stand hunting, the 10 is also the best in the field. I prefer the bull [round] barrels.
This is where I shop when overwhelmed by the fever:
1-Contender classifieds, here on GBO
2-Ed, look at his web site, then call
3-GunBroker, even if you don't register you can look around
Some of the retailers have new barrels.
Good Luck with that fever thing, P.A.
