Can someone tell me the dimensions of a Model 10 Standard contour barrel as well as the dimensions of a Model 10 FP-SR Heavy Barrel .308. I want to take a wood stock from a model 10 GXP3 and re-channel the stock to fit the FP-SR and I need to know how much wood would need to be removed from the barrel channel. I have the FP-SR, but I do not have a GXP3 so I cannot measue it myself. I would appreciate any help or advice on the topic.
