Hi all, just my 2c worth here. Ithaca is right about swapping components, but and there is always a but, you can if the manufacturer gives the green light. Just as an example, one of my loads calls for Fed 209 primers, but they are discontinued, but Win 209's can be used instead per the powder companies okay. So, to be safe always check and double check.
One thing to save you pulling your hair out, is kind of watch what you post on some of the other forums. Whenever you ask about LP loads, your going to get....."Why? You don't need low pressure, high pressure is your friend" and so on. And for some of the guys, no matter how much you explain, it just doesn't matter. Better to stick here with folks who understand vintage guns. You'll have more than enough good advise on reloading.
As to cold weather loads, I've had good success with 800-X powder, meters like crap, but performs well in cold weather. I keep my pressure around 7000psi and a MV of around 1200fps. And yes I do shoot 2 3/4" reloads in my short chambered guns.
Good Luck!
Greg
