I am almost as big a fan for Leupolds as I am Winchester pre 64 mod 70's but in the last week I have had 2 small issues with their mounts, I am on a DualDovetail mount kick as of late, they just look great on my pre 64's and in the past have been strong as a Brahman bull but I have had the dovetail break off as I was putting even pressure turning it in with a 1 inch wooden rod, no biggie I bet bass pro will make it good, today as I was getting ready to test my std, 62' vintage 300 win mag I noticed the front base was cracked from front base mount hole to front of the base, I torque em well and have a good feel for torque after many years of servicing PT6 engines on my Airtractor cropdusters, have any of you guys had same type problems, Im wondering if they got a bad batch of steel in ? very best WinPoor
