i have the heavy barrel, from the factory, in .17HMR that was fitted to my frame by the factory and it's not very accurate at all.

...it could just be me and something i am doing wrong.
i have, in fact, set it aside for a while to mull over what to do. hopefully i can figure out what it is that is the problem; me or the barrel.
i have a .22 mag barrel that shoots wonderully from the same frame.

it's not a 'tack driver' per se, but is, none the less, very acceptable for hunting.

i believe that the barrel is so heavy, it creates problems some how...
where i like the .17HMR, in this case, i may just stick to .22 WMR
