If you want cheap throw lawn darts.
I just turned a 6mm X-Caliber Apachie barrel on it but the dies came in wrong so I am waiting on the replacements, they were supposed to be here 2 weeks ago now they tell me they will be shipped tomorrow.
The 243 was still shooting real nice groups well under .5 but it has just over 1500 rounds down it and I won't take the chance of it going bad at a match.
