Here you go. 3280 ft per second 180 gr accubond. Please disregard the fouling shot. 82 gr 7828.
Looking at Hodgdon's website IMR 4955, is faster to IMR7828ssc and almost identical to IMR7828 in burning rate, I don't have IMR4955 and I've run out of IMR 7828, darn it.. I need to order IMR 7828, IMR 7828Sssc, IMR4955 and IMR7977. I have plenty of RE 22, RE 26, Magnum and H1000. I'm trying to change to temperature insensitive powder and powders that do not leave much copper is a plus. Well there's lots of time between now and late September.
I prefer classic.

I use 7828SSC in the 257 and 300 Weatherby calibers with TSX bullets. Great accuracy. Load to the top of the range, set to book max, and you're already very close to the perfect load.
It doesn't work as well in the 6.5-300 Weatherby, where US869 works for me.

I use 75 grains of R17 with 180 NBT for 3100 out of a 24 inch Vanguard. Wicked accurate and pretty easy on the shoulder. Have 8lbs of 7828 to play with eventually.

7828 seems to be the cat's ass in Weathery's from 240 up through 300's. Not tried it yet in a 30-378, as I still have some H870 to burn up with that one.

Pure and simple, a 300 WBY will push a 180 grain NBT or Accubond at 3200 FPS with 7828 powder and kill anything you point it at. 7828 is a great powder for accuracy and velocity, forget anything else you hear about what works best as nothing will work better...
I’ve posted this before. I had Robert Kleinguenther do some work for me in the late 80’s and early 90’s. He found out I handloaded and I passed thru Seguin pretty often heading to South Texas. He asked me to load some ammo for him in 300 wby and 257 wby. He gave me his recipe for both loads. His load for the 300 involved 7828 and 180 grain Hornady flat base Bullets. Worked and gave excellent accuracy in every rifle I tried it in. Now for those that don’t know he worked for Weatherby in Germany when they were built there. This was before Weatherby moved to Japan.

Hasbeen I am with you on this, but it seems that some people think that if they keep posting their opinion, it carries more weight. That is fine and dandy too, but it doesn't change how simple a 300 Weatherby is to shoot 180 grain bullets accurately and consistently with 7828 powder. I will also add that you don't need a premium bullet to make it kill either...
