Reinforcement of the stock at the tang inlet is something I consider mandatory if that area is to be used to absorb the recoil force. Depending on the actions tang shape, I've used round G10, round 7061 and rectangular 7061 with good success. Angling this material through the pistol grip area is a good thing.
You have to take the tang shape into consideration as well so it's not acting as a wedge on the sides and rear corners. A small end mill to relieve the stock corners on a Panda style tang works nicely with at least .020 side clearance on the bedding.
On a bolt in, a front mounted lug is always my first choice.
Al, Do you have a picture of the stock reinforcement you've described above? I'm having trouble picturing it. Thanks, Justin
It goes right here. I profile the tang end of the material to match the flat of the actions tang.There's about .030 of bedding material between it and the rear of the tang. If you look closely, you'll see where the corners of the tang inlet have been radiused with an end mill.
The angle of the reinforcement depends on the pistol grip area of the stock being done. On this one, it's like this:
Hope this helps. -Al
