I know of 3 with split stocks, two laminated and one a standard wood stock. My 338, another guys 300 win, and the standard wood stock was a 9.3x62. All cracked in the same way, just a inherent weakness in the recoil lug/stock setup. I talked to a guy at Extreme rifle works here in alaska were I am having a 375 lightened up about it. He told me that they have done several of the T3s with stock problems. One of the main things Extreme rifle works does is custom lightweight kevlar stocks, he was the one that told me the fairly easy fix to the tikka problem. THey just sandwich a tubs, rem 700 style, recoil lug between the barerl and action and rebed.
Other than the stock problems I was actually pretty pleased with the rifle. I would have never thought to look at the recoil lug and had it not split would probably never known of any inherrent weaknes. My main problems came with berretta usa not wanting to fix it due to my having it "altered". Since it had a muzzle break they wouldn't do any repair work to it, I guess it voids any warrantee. Thats what really pissed me off. All I wanted was a new stock. I don't see myself ever having one again but to thier credit they are usually pretty accurate. I was a little gun shy about getting one at first due to thier explosing barrels problem they had for a while there on stainless models. Before you get one make sure they call in the serial number so its not one of the recalls. I guess they had a bad batch of stainless steel that was exploding.
