Yes its on the tape. 2553 avg. I am using a jefferson outdoor hinged floorplate, I believe it allows up to 2.485 something like that.

Not sure how helpful this'll be to most, as I'm shooting 243 fast twist loaded long, but I've been trying some powders that I have on the shelf that I don't currently have a particular use for. Seeing if I can find a use for this oddball stuff that I bought when I was happy to be able to buy anything labeled gunpowder.
Anyway, I've tried the loads below, and have settled on my load for the year.

Going to load all these I can with the 2 pounds of powder I have.
243 17 inch barrel 1-7 twist
243 116TMK - 2.96 AOL
Hodgon Superformance 43.4 grains
