Lulu, a 10 yo mixed breed suffered a stroke Monday before last and died 4 days later. She will be missed. On the up side we went and bought a new puppy, a 9 week old Harlequin Great Dane puppy with crystal blue eyes that's been dubbed Dammit. She's beautiful and playful but our 7 yo Boxer, Bijou, doesn't quite know what to think and hides all her squeaky toys from her. She'll most likely top out at 140-150 lbs. God help us.
It seems to me that cheap unreliable .22 rimfire ammo is becoming more common these days. At one time this concern was less of a problem so no need for such a redesign, but with the crappy ammo proliferating today maybe a fix like this could be a viable option. I'd suggest though that everyone just purchase quality ammo which doesn't appear to suffer these failings.
