Re: Remington 597 .17HMR Recall
The 17 HRM is the only rimfire to exceed the preasure of the 22WMR. (except the 5mm Remington mag.) it operates dangerously close to the design limit of the rimfire case. The case can only be so thick for the firing pin to be able to crush it, setting off the round. The 17HRM operates at 26,000 psi and the 22 WMR at 24,000. Hornaday wanted more performance and got it, but only with a price. In bolt actions it is fine, but in semi auto's it is too close to the limit. Out of battery firing, ie., excessive head space with this much preasure destroyes the case heads, and damages guns and shooters. It would work, but careless cleaning, or lack of cleaning contributes along with slack tolerances, common in semi auto actions, won't let it. These are the problems that have lead Remington to this recall. The 17 HRM is just a bit to close to the practical limits of the rimfire case. I hope the ammo is available for many years to come though. It would be a shame if it went away.
