RE: Need a good load for .450 marlin
ETW,
Please don't get me wrong, I think the 2-7x Variable scope is a great choice for this gun. Having said that, I'm not sure that the scope of your choice will hold up to the recoil. I don't know anything about your scope, but I do know that this weapon's recoil eats scopes for lunch. Since you've only shot 9 rounds through, my guess is you haven't experienced a failure yet. But then again, you're scope may hold up, who knows.
I put three different low-end scopes on my .450 from various manufacturers and all eventually gave up to the recoil. Now, word has it that Leupold and perhaps some other high-end optics will take the punishment, but I decided to mount mine scout style with long eye-relief, so I chose a Reddot instead.
Please think about this before you head out hunting this fall and make sure you scope won't fail in the field as mine did. It was very frustrating!
