Thread: 17hmr

There seems to be clusters related to the mag change, possibly breaking position to reload? Rimfire I find is quite sensitive to hold position . @mudgripz might chime in hopefully.
I havn't seen the lot to lot change in HMR being any where near as relevant as with 22LR. I have a couple of different lots of the cci 17gr HP here. If you want to try then I might be catching up with R93 at easter, he could take them back

Scatter random throughout the mags. Haven't had a .17 in many years and I'd forgotten how little recoil there is, cool to watch the trace dropping in at 100m. Not much movement of the rifle. The high/low shots were often directly observable off the chrono - see a high shot and look at the chrono - yup 100fps faster.

A feller on RFC got the best 50rd .17hmr group with the same stuff at 1.375moa, but from a very heavy bench rig with a lilja custom barrel & 32x scope etc.

I'm going past a couple of gunshops this week so I'll see what else I can pick up to have a play with - cheers for the offer I might take you up if I don't find anything else on my travels.

The .17 is fun

The first two seem so and not unexpected with ammunition that dosn't suit the rifle but the third with the a more favorable load shows three distinct groups.
The only brand I saw really large es from was CCI A7. It was truly horrible . I havn't chroned any from some time now , Ill try the stuff I'm using if I get a chance.
