I see lyman has loads for up to 7.5 gr Unique for the 45 acp with 200 gr cast boolit. All my other books call for more in the 5-6 range. Any one here try 7 gr unique? I have tried 7 gr in my just right carbine. Very accurate but has some recoil to it. I dont want to pre maturely wear out my gun. What do you guys think?
