You're a better man than I am, Gunga Din.my pet load is a 300gn XTP with 44grains of Lil'Gun. Pushes it a little over 2000fps and about 2900lbs of energy.
Not really. Your sixgun weighs at least five pounds, has a bipod and a muzzle brake. A lightweight .44 or .454 will be much harder on a scope than your short rifle..44 mags and .454 Casull's may be hard on a scope but the true test is this beast.
Pressure is irrelevant. Recoil energy and velocity is what is relevant and a .44 or .454 that weighs half as much will place far greater strain on a scope than your monstrosity. Your sixgun, without all that crap on it, goes 82oz. That's 5.2lbs plus an oversized scope which will be at least another pound and a bipod that probably pushes a pound too. Sorry but this is basic stuff..44 mag has no where near the chamber pressure of the .460 and .500 mags.
Pressure doesn't destroy scopes, recoil does. Sorry but a 7lb .460 is simply not going to punish a scope like a 40oz .454. Perhaps you're confusing muzzle blast with recoil???I own several .44 mags from a 4.6" Super Blackhawk and to a S&W PC model 629-4. Also have owned a .454 Super Redhawk in the past. They do not compare to the .460. And is you think champer pressure is irrelevant then you obviously never shot one. Heavy bullets loaded to the max make for a shock wave that will definately get your attention.
