Do you want 4695 loads for .308 or 4895 loads for .398? Just kidding, I have often wished for a numchecker application like a spellchecker.

They should have some good loads for these calibers. There are too many variables peculiar to each any every gun that may make someones "favorite" load a deadly load in another gun.
