Thanks, guys....I've a bunch of cci 400 to burn through, so I'm feeling like I want to stick with them for the time being. I have not crimped in the bullet, just used neck tension. I also have a bunch of .224 Sierra round nose 45 gr. bullets and am trying to work with them also. I think my options at this point, that is the first/easiest things to change are the powder and bullet seating depth. Any thoughts on these parameters as they might contribute to improvement?

Thanks again!

Dennis
