Hello from BC Canada.
I'm new here but have been collecting 1899's and 99's for several years.
Looking forward to sharing info with other 99 collectors.

The savage 99 crack can be prevented by removing the buttstock, making a brass shim and bending it around the recoil lug on the lower tang.
Drill a hole for the stock bolt to pass through, and put it all back together.
When done right this will provide relief in the upper tang, so the wood and metal is not making contact any more.
I'll try and post pics here in a few days.
