please forgive me if these are blindingly stupid questions, but I would prefer to ask than find out the hard way.
i have this week started reloading and had a cracking weekend working out loads. My reloading kit is just the classic Lee loader but with that, 35.3gr of IMR 4064 and 87gr Vmax I am getting .4 inch groups at 3025fts. As the gun is new to me I haven't actually shot it before working up the loads so I am happy this far.
along with the gun I picked up some fire formed ppu brass which I have used to build up my loads. So finally onto the questions.
1. Can I use brass that has been fireformed in another chamber ?(cz 601zkk)
2. I have also been given some once fired ppu that has been fully resized. Will this differ much from using the fire formed, necked only?.
3. What difference should I expect if I changed my brass to say Norma ? ( that is probably too big a question), feel free to answer "many you idiot".
4. As I have been using fireformed and necked brass. Would my load behave differently with new brass?.
thanks for any advice 😃
