I've never used that exact mount, but I agree that you should certainly reconsider using the epoxy...although I don't believe that brass is really a suitable alternative...the epoxy may of course soften and reform itself in heat which would be a HUGE issue, however, a smaller issue would be the thermal expansion of the materials which would change your POI. When you sight in your rifle on that nice day in October, you may end up shooting low in January, or your scope mount might become loose, and as you're shooting, say you've got to take a few shots, your POI will be changing since your bbl will be warming up. It wouldn't be a HUGE effect I wouldn't imagine, however there likely would be some noticeable effect.

I only honestly replied to this out of my HATRED for the use of epoxy on guns, and to reply to comments made by Brush buster about the .30-30 only being good for 100yrds and not validating the use of a scope. I could not disagree more!!! No, you may not wish to use the .30-30 past 100yrds, and I admire your self control as you watch bucks walk by "out of range", which if YOU can't shoot well enough to use it past 100yrds, then they ARE out of range, however, don't discredit the .30-30 for no reason, I've got a Marlin 30A (what the 336 used to be) that I'm loaning to a friend that will shoot 2.5-3" at 200yrds with factory loads, I've never hunted deer with that one, but he's taken a half dozen deer between 130 and 180yrds in the last four years (lazer verified ranges). Typical hunting loads for a .30-30 put it at about 1000ft.lbs. at 200yrds, typically still around 700ft.lbs. at 300yrds....The power is there. The accuracy is not always there, however, which may not necessarily truly be the rifle's fault.

Sights can make a rifle more accurate, simply being able to shoot at a hair instead of a deer is incredibly useful in accuracy. Mounting a 20x scope on a rifle that will never see a shot over 50ft. isn't smart, but he hasn't said what his circumstances are, I've got a scope on my .44mag Ruger Super Blackhawk, instead of being accurate enough to hunt deer with to 50yrds, now I'm able to make 100yrd shots consistently.

Any rifle that would shoot over the range that a scope's field of view allows can be improved by adding a scope.
