Mine loves my handloaded 50 gr Vmaxes, loaded over surplus (old) BL-C2, and Rem 7 1/2 primers:
The only thing I've done to mine is to stone the burrs off the trigger edges. I did not remove enough to change any of the angles, and I backed the spring tension off a little bit. Other than that, it's factory stock, at about 4 pounds.
I will say I didn't have much luck with the factory ammo I tried in it. I only tried Black Hills and Ultramax. Mine didn't like either of those brands.
It wrecks havoc on the local varmints though...
