Your 338 is 7 flat with a scope BSA?
Nope, with scope mounts. Running aluminum bottom metal helps lighten it a little. Plus the H&H receiver is slightly lighter than a standard receiver..
It was 7 3/4 pounds with the Swaro on top:
Now it is around 8 pounds all up with the Conquest on top. I prefer the Conquest over the Z3 Swaro. As for bottom metal, like I said, never have had an issue with any model 70 factory bottom metal. Especially the pre 64 models. I know there are guys that swear they have issues, but it always makes me wonder. I am known to tinker and fine tune my rifles though. I've ran into issues where the bottom metal may need to be glass bedded or a simple washer added as a shim. Whatever it takes to make it work and not cause issues. I don't think a pricey aftermarket bm is really worth it, unless it's a full on CUSTOM. Some others may disagree. I will say this, like I have in the past many times before: I will not use a rifle that does not function 100%, 100% of the time.. Hint.. Oh, and you know me well enough by now that I don't even have to tell you how accurate it needs to be...
