Thanks for the input. I am leaning towards the .221 but will probably end up with barrels for both before it’s over.
I've got a barrel for the 17 Fireball, on a Savage action... as soon as I can find that darn barrel nut wrench....
and although I can load a 223 down to 221 Fireball speeds, so don't need one....
I think your solution is by far and away the best solution possible... on a TC, one of each...
I wish on that TC Compass I have, that they would do a varmint platform and make it available in all the varmint cartridges that are based off the 223 and its derivatives..... even be better if they were as easily changed as a Savage is....
