FQ, it is a valid question, for certain rifles and pistols, I choose factory ammo for SHTF, of course I try to match the best factory ammo for the particular firearm, But if I am reloading, why not come up with the best combo, for this firearm?? Once the initial load development has been done and the perfect load decided on, invest heavy in those components, now these days, it is not as inexpensive as it was before, I have for a long time, found powders that agree with several firearms, rifle or pistol, maybe not the best, but very good, and then bought 8 lb kegs of each. In competition I want the best, not that important in pistol, but in rifle, it better perform, or I lose. Reloading for the SHTF scenario is completely different, you want the most versatile powders out there, that can work in every firearm you own, that is different, and understood, but for now, I have the stuff to load my favorite stuff with what it likes.
My longest, hardest shots were prairie dogs, basically squirrel sized animals, at 600 yards +, that takes an accurate rifle/load
combo, try it with your rifle and factory ammo, I think you would be disappointed, but maybe not. There are such things as SWEET rifles, with factory ammo.
True enough, most of us, don't need to shoot anything bigger than a pie plate under 200 yards to defend ourselves or put dinner in the freezer.
