If it's a fun shoot, I doubt you need a big money barrel. I put one of the barrels Browenlls sells on one of the kid's rifles and if all the bullets don't go in the same hole, it's not the barrel.

I've got one of the Ruger target versions and that barrel is outstanding. Dunno if the barrel is available separately.

Do get the Ruger target trigger. Much less fuss than reworking the standard one and way cheaper than the big name ones.
