An outstanding fast burning powder, 700X was my go-to powder for most of my reloading chores.
3.6 grains works well for the 125 grain bullet, and 3.8 for the 115 grainer. Dropping any lower chargeweights increases the powder deviation. Remember, with few exceptions, progressive powder measures will alway have some deviation of throwing a bit more powder, but more likely a bit less, or a case with a lot less.....
