Has anyone heard of any recalls of the Winchester model 70 in 7mm WSM caliber or recalls of Winchester 7mm WSM ammo? Recently a friend's rifle using factory Winchester ammo exploded. When I say exploded that is just what happened. Rifle parts went all over the place. He was lucky and suffered only minor injuries. A few months later his father had the same thing happen to him. Both rifles were bought at the same time at the same place and the serial numbers were within about 200 of each other. Both were using Winchester factory ammo bought at the same place at the same time, but I do not know if they were the same lot number. I have looked on the internet and found nothing. Winchester replaced the first rifle but (I am told) refused to replace the second rifle because, in the past, hand loads had been fired in it, although it exploded using factory ammo. I do not mean this as an attack on Winchester or their rifles, I am just asking about possible recalls. Thanks.
