To be that flat a shooter, is it likely to fire a round heavier than 30-35 gr.? Even then, how much juice would it have to have behind it? Sounds like a .204 (as Jeepguy guessed) with maybe some new over-sized case/charge...? At the "speed" the new 17 Hornet is coming to market (or not coming to market) with 2 of the biggest names behind it..Hornady and Savage...I don't have much faith that this new "game changer" will on the shelves any time soon. Also, Winchester and "precision rimfire" aren't 2 words I ever expect to hear in the same sentence, so I wonder about any accuracy claims. Another thought.. 17HMR is about $15 a box, so add 15% and that's $17.25. People complain that premium .22WMR and .17HMR is knocking on the door of centerfire ammo costs, so I'd be curious to see what "niche" this fills. I've had my fill of rifles that shoot obscure ammo, so longevity would be real concern. Very interested in hearing more about this..in spite of my reservations and scattered thoughts.
