The Limbsaver 10001 pre-fit pad is listed as fitting on the wood stocked #1's. I'm going to try that first. The last rifle of the set, the "Elephant", will be in .450 NE. They haven't been produced yet, but I've lucked into finding a guy that is going to be getting a couple that are not already committed, and he's going to let me know when he gets them. I'd love to have one in a NE caliber. When they're all done, he will have the whole set of five with matching serial numbers. AWESOME! There are only 250 of each rifle being produced.
