kymike,
What works in my Blk. Diamond XRmay or may not work for you. Finding the load that works best in your rifleis half the fun.
There are so many bullet/sabot combinations, and new powders on the market now that you just have to get in there and try them in your rifle.
I do not shoot maxi's out of my Blk. Diamond and I don't know how well they'd shoot for you.
I would recommend saving/filing your targets with the loading information you used. This way you have a reference to go back to, with what worked and what didn't work.
