.17 rim fire in semi-automatic weapons


#1

In looking for info on the 50AE headstamp discussed in another thread, I found this on the Magnum Research, Inc web site (magnumresearch.com/) regarding .17 rim fire ‘performance problems’. The problems arise from the use of .17 rim fire in semi-automatic weapons. Remington also had a recall on its Model 597 17 HMR semi-automatic rifle, and was offering $10 coupons for each full box of the ammunition returned, also. Does anyone know specifically was problems were encountered?

Update to previous warning published by the prior Magnum Research Inc. on its website July 15, 2009.
In June of 2010 Kahr Arms purchased certain assets of Magnum Research, Inc. ® (MN). We have since incorporated
a new company named Magnum Research, Inc. ® (DE).
Although we are a new and different company, we would like to accommodate customers of the prior Magnum
Research, Inc. ® (MN). It has come to our attention that certain lots of 17HMR and 17Mach2 ammunition may
exhibit performance problems. These problems could result in damage to your rifle and may be capable of causing
injuries to shooters or bystanders.
As a result, we strongly advise immediate discontinued use of rifles chambered in both 17HMR and 17Mach2
calibers due to these ammunition performance problems. Although performance of ammunition is outside
the control of Magnum Research, we take safety concerns seriously.

The blowback actions opened too early, and as a result, some cases would then rupture.
