Win 780 in .243
Has anyone tried this powder in the .243 with 95gr bullets? It looks like the burn rate is close to RL22 and other magnum rifle powders. I have some and want to try it, but so far I havent seen any data. Any help is appreciated!

vapodogHodgdon's max load is 48 grains for a velocity of 3138 FPS.....not bad at all!
Thanks Vapodog! Right now I am getting 2900+ fps from H4350 and IMR7828. Both loads a very accurate, but if this powder gets anywhere near 3100fps, I will be happy with it! Kind of hard to leave 200fps on the table.

Not exactly shabby either.
I'm using the last of my H-450 in my .243 I'll probably switch to Supreme 780 when it runs out!
I'm pretty pleased with it. The loads I use are in the Hornady manual, and it's nice that they used the same rifle I have to develop the loads, a M70 w/24" barrel. I get the velocity they say I should be getting and are accurate as well. I am using Nosler BT's in my rifle though.I had tried some RL22 in it and got some really fast speeds compared to the manual, like over 3100fps on a load that should have been around 2950. Took it out another day and it wasn't nearly that fast. Chalked that one up to the chrony and a funny sun angle/intermittent cloud cover.
