Hey Bob,
The 223 barrel is an excellent choice for a reloader. They are very accurate in the TC.
I would also, consider the 22 Long Rifle. I bought one this year from Ed's TCs and it was a 16" bull barrel from the Custom Shop. In a hangun configuration it will out shoot both of my 22 LR rifles. It is cheap to shoot and no reloading.
I have a 223 barrel that I wouldn't trade off for anything, but that 22 LR will never go either.
Difficult choices.
