"In time, you're likely to find that company X makes the best size die for your use, while company Y has a better seater."
Mr. Thomas, I understand your point but I haven't found that to be true. On average, I HAVE found about as much variation between dies of the same caliber from the same maker as there I have between brands.
It seems no brand has a lock on being made to "tighter tolerances" than others. In fact, it seems all makers vary within the full range of tolerances allowed by the SAAMI standards. Ditto with our chambers. So, getting the best match of dies, either sizers or seaters, to a specific firearm is pure chance. I measure the fit and select the best I can find, the brand being irrelivant. At least to me.
My Sako 22-250 sure loves you guys 36 gr. Varmint Grenades! Me too.
