I have the VHZ as well, and got some load testing done yesterday.
My best load so far is:
40gr. Nosler Ballistic Tip
12.1gr. of AA1680
It produced a 4-shot group of .63" at 100 yds. There was a slight wind coming through at the time.
Velocity is probably around 2680fps or so. I'm thinking of trying a little higher (max load specified is 12.5gr), and see if anything tightens up after that. I've got a feeling to stick with the 12.1gr. though. Any advice?
By the looks of things, I might get some Lil'Gun and see how that performs. I replaced the trigger with a Rifle Basix that breaks around 2lbs. 13oz. Sure feels better than the one from the factory.
Note: I began with the published starting load and worked up to my specified charge weight. Do not attempt to load that in any 22 Hornet rifle without first consulting a reloading manual and proper reloading procedures are observed.One last thing, about how many reloads can be had from a standard 22 Hornet casing? I've read about the case walls being thinner than most and should be checked for any case head separations after every reload. What has been your experience?
I have edited the trigger pull weight, as it seems to have broken in a little more. I checked the set screw, and it has not moved. -Patriot
