Back in the 1970s I worked for a gunsmith and we had quite a few Remington 788s come in with busted bolt handles. IIRC, most were in 22-250. I never did see an M700 come though during the time I worked for him. I have 3 M700s myself and the last time I looked the handles were still on them. Never did use any of mine in sub-zero weather so I won't comment on that aspect.

Our forefathers did not politely protest the British.They did not vote them out of office, nor did they impeach the king,march on the capitol or ask permission for their rights. ----------------They just shot them.
