Hmm... All valid points. Im still green behind the ears with casting. But one of the things that drew me to coating bullets as opposed to lubing them was being able to do a pile of them at a time and shoot them whenever I wanted, with whatever lead I wanted. I am not hunting with them, and am not shooting anything other than 40sw (at the moment). So as far as my knowledge goes, I didnt think the hardness of my boolits would really make any difference as long as I am not getting any leading.
If that made sense - let me as this. Are you mixing the same alloy for your current coated boolits as you did with regular lubing? If so, what benefits does that serve? I shoot mostly all range lead. And honestly couldnt really care about the little bit of leading I have had using DARR lube. BUT - If I can continue to shoot just range lead with no mixing of alloys and COAT them and get no leading... Why would I want to bother with using a harder boolit?
Thanks for any insight.
