.308 favorite load?

About the 4th time you have IMR3031 bridge in the drop, then drop all over your shellplate... you'll start to think about ball powders more seriously... Having said that, I still prefer the end performance of extruded powders, although that might change if I ever get to try TAC, which has been described to me as Utopia in a can for 5.56mm and 7.62mm.

I don’t know if it is Utopia in a can, but have loaded over 30 pounds of it through the years, the vast majority in .223/5.56 with some in .308 and just a bit in 22-250 with 40 gr bullets and a dash in 30-30. Very versatile powder, meters like a dream. Glad to have a couple 8 lb kegs on hand, and when I get to the last one, will start searching for another one or two, again.
The local Sportsman’s Warehouse had two 1 pounders on the shelf this morning when they opened. They won’t last long.

The last time I used 3031, it was still in the tin cans. It was still a long extruded powder and would have been a pain to load in a 223 Rem. There is some information on the net from 2017 that says 3031 is now a shorter grained extruded powder than it used to be. I haven't seen a current plastic bottle of 3031, I haven't seen the current produced 3031.

Does anyone know if that is true?

I happened across TAC about a month ago and grabbed one to see what all the noise is about.

For 5.56 preliminary model shows great promise and good efficiency at 25+gr. Below that burn rate drops below 85% Have not built a model for X51 yet, but I have a few minutes this AM so maybe I'll run some numbers. Unfortunately this summer is a disappointment with all the rain and trying to squeeze outdoor house projects in between.
