[QUOTE="30calyooper, post: 1575399, member: 107258"] Yes, 215M will actually work very well for consistent accuracy with ball powders like W760 and Ramshot Hunter in the '06, and it would not surprise me if it worked well in 243 with the right powder/bullet combo. Just remember that it IS a magnum primer, so if you've got a pet load with any particular powder, you need to re-check it for pressure by starting low and working back up. Same as you would do for any change in brand of primer or brass. BTW, be especially cautious and very watchful if using any magnum primers with "fast" ball powders like Mil-spec WC844 and WC846, and the quicker stick powders (think 4895 or faster.) The hotter primer can easily create pressure spikes with faster powders that catch you off guard...The consistency of your velocity and accuracy are improving as you slowly increase the powder charge, then all of a sudden velocity goes all over the board and accuracy degrades. It may not be enough pressure to show classic signs like ejector marks on your brass, but that sudden loss of consistency means you've stepped past the practical limit for that combination of components. Don't be surprised if some of your favorite loads like bullet 'X' with powder 'Y' and 'Z' brass no longer pan out. While the 215M is certainly worthy of the name "Gold Metal Match" it's still a MAGNUM component and that changes everything. [/QUOTE]
