Why load your ammo 0.005" shy of a kiss? Unless it shot better that way, of course, but there's no reason not to start at the start...
Yup, 43.5gr of IMR4350 for around 3113fps on the chronograph, but my drops match the data for 3157fps. I have lots of 7828ssc, but I also have about 8lbs of IMR4350, with nothing but the .243AI to use it in. So far, I can't really ask for more than IMR4350 gives me, except for maybe 100fps more velocity Absolutely great accuracy, pretty good velocity, and I haven't noticed any real temperature sensitivity in this application. Once that IMR4350 gets burned through, I'll likely try H4350 or even H4831sc. I'm sure 7828ssc would work wonderfully, as well.
