I once had quite a few more various calibers and all were very nice firearms. However, my financial situation changed drastically and I sold them all and downsized. I don't feel outgunned or undergunned.
My firearms aren't necessarily my "top choices" to own but they're all better than I'll ever be and will outlast me by a long-shot. I do very much prefer semi-auto vs. bolt but I can't complain about the Axis which replaced a very nice .30-06 BAR Gold Medallion.
I would really like a .458 SOCOM upper which could effectively replace the '06... but I'd REALLY need to get into reloading to afford shooting it. I would like a .22 LR but recently got fed up with poor availability and skyrocketing prices of ammo of all rimfire... and there's truly nothing around here requiring either .22 LR or WMR that a good pellet rifle and .223 Rem can't handle.
In my above list of what I own, I intentionally left off the Remington 597 WMR because I don't intend to keep it. Although it nicely fills what many would consider a "void" between the pellet rifle and .223 Rem... this area doesn't have any critters between a squirrel and coyote so what need does it fill... especially at 30 cents per round?
I also didn't include, in my list above, a Savage Axis in .223 Rem because I'll probably sell it since I have a nice AR in the same caliber and I do prefer semi-auto and I don't need the sub MOA accuracy anymore.
If I sell the .223 Rem Axis I'll probably use the money to help fund a .458 SOCOM upper and associated reloading gear... but will probably have to sell the '06 Axis too. That's okay because although I like the Axis bolt rifles I really do prefer semi-auto. Did I mention that I prefer semi-auto? After selling both the Axis bolt guns and 597 Rem I can afford the .458 SOCOM and basic reloading gear. That'll be a happy day.
Now that I've bungled your thread with my ramblings...
Actually, I'm just sharing my personal thought processes RE my own firearm choices. Maybe it'll help with your decisions... maybe not.
EDIT: On the other hand... I do prefer to have a backup or two of certain calibers and the two Axis bolt guns very nicely serve that roll for the two ARs. Are you confused yet? I know I am. My very thin wallet will make my mind up for me though.
