NOTE: NO LARGE DIAMETER HIGH PRESSURE CARTRIDGES IN THE ENCORE..... NOTHING LARGER IN DIAMETER THAN THE "H&H" HEAD SIZE OF .300 WIN. MAG., 7MM REM. MAG, ETC.
No short mags!
No super short mags,
No compact mags,
No ultra mags,
Nothing high pressure larger in diameter than .512" at the head of the case, the approximate diameter of the H&H headsize above the belt.
I get requests for these daily. They are too much for the Encore and stretch the frame too much. The Encore is NOT the equivalent of any decent modern bolt action and will not handle the additional force exerted from the larger diameter chambers.
It is a matter of pounds per square inch. The cross section of a mag chamber at .512," for example, is a larger fraction of a square inch than, say, a .308 Winchester chamber at .470" and therefore exerts more force out the back of the barrel.
I like to use the reverse analogy of your lawn mower engine and your car engine. Both use approximately the same octane fuel and the same approx. 15 to 1 air to fuel ratio, but to get MORE force on the crank your car engine pistons are much larger in diameter. The pressure inside the cylinder is the same, but the surface area of the piston is greater.
In your car engine, you WANT more force. In your break open actions you must minimize the force out the "cylinder" by the "piston'" the cartridge case. To do that, you stay with the smaller diameter cartridge/chamber.
There are more reasons NOT to chamber for the large, high pressure rounds, one of which is the depth of the screw holes in the barrel over the chamber.
The other is that even if good sense does not prevail and you do chamber for one of the large diameter, high pressure rounds, to avoid stretching the frame you have to either long throat the barrel to reduce pressure or you have to download it to the point it may not produce as much velocity as a smaller diameter cartridge that is acceptable.
The "short fat" and hot mags should be reserved for bolt action guns or stronger fixed barrel single shots, NOT the Encore.
You have much greater issues to be concerned about than a few extra feet per second to plow up Mother Earth with a bigger furrow when you miss.
Focus on accuracy and dependability of the TC system first!
Then respect the gun for its worth rather than stretching things to the limit!
Shoot Smart!
Don't do dumb things.
