True. The recoil formula doesn't use pressure as a factor. However, we all know or should know that in general, the higher the pressure, the heavier and faster the load is ejected, which are recoil formula factors. Loaders can vary powders , primers and crimp depth to affect pressure . Chamber pressure and recoil are not fully separate although the formulas are. However, this subject matter is only important for knowledge purposes. For the general Parker shooter, he has a strong gun that can take substantial loads up to and including many of the so called high brass shells of today.....but not including some of these 1350 -1400 fps 1 3/8 oz loads that some manufacturers tell you that you need for killing pheasant.
