Thank you for posting that. I wrote that up late, and I am pretty sure I typed some errors. For example, the 300grns should be a max of 22.1 grains, not 22.3. I also typed 250 grain hornaday when it is 240grn mag.
I'll pull a few of the 300's today and see if they are 22.3 or 21.8 as my load notes say.
I do most of my velocity testing via my freedom arms model 83 454c. I'm not to worried that the pissing hot 45c loads will be much of an issue for it compared to the moderately *tame* 454c loads i've fired.
