Can somebody please recommend a good 1-piece base for the Savage 25? I bought a DNZ one-piece with rings; the description said that it fit the 25 but when it arrived the holes didn't match up correctly. I tried the base on my model 11 and it fit perfectly. I'm having trouble finding a base because most have a description that says "universal SA Savage", and I'm afraid of buying another that doesn't fit. Anyone have any suggestions?
