I have a few guns that I shoot 5-6K shells in but have decided to review my practices. If a gun is not able to safely shoot 7K loads it is probably best not to shoot it at all. If it is only safe to shoot with extreme weak loads thats a concern it really is tough weak to shoot at all. Since I have many other guns to shoot it just seems best to retire the ones I am concerned about due to safety issues.
When you raise you pressure level to 7K you get a larger variety of loads to try. Most do very well, even in cold weather. Once you decide to reload your options get better. If you accept that 1100 FPS kills birds just as dead as 1200 or 1300 FPS velocity does not matter. Pressure and patterns become what you choose from. Larger shot size retains energy down range and helps make slightly slower loads performance better on live birds.
