I believe I've finally found the load for my Remington 700 BDL .223. Using fire formed and neck sized brass I loaded 5 rounds each with 27.5, 27.7, 28.0, and 28.3 gr of CFE223, 40gr Hornady V-Max bullet, and COL of 2.255. The best group is using 28.0 gr and is .355" center to center (.380" outside to outside) at 100 yards. I plan to repeat the test again just to confirm it was not a fluke. That is the best group I've ever shot. It's pretty amazing how much difference 0.3 grains of powder can make. (btw-those are 3" targets)
I don't know what an "MV" is so I guess I'm not compiling any data. I also don't know what you are referring by "what's it at"?
I've been at it for a couple of months, but I have not been able to get to the range as often as I wanted. It's been raining here about every other day and the range is mostly a swamp.
According to the Hodgdon website the max load for 40gr, .223 bullets using CFE223 is 29.0 gr. I haven't gone to the max yet, but will if the rain quits for a couple of days.
Nice group! It's a good feeling when it all comes together like you want.Load away! Joe
