Welcome to the forum...have you checked with the manufacturer's site for their info?
I wish they had data but I'm finding it really hard to find load data for the 280 Ross. I've been using 4350 with ok results thought I'd try something else tho.
I just checked the Load Data site and with what little they have on the Ross that powder N-204 (Its even way slower than Reloader 25) it in my opinion others may differ is way to slow for it.
Your using 4350 at present this equates to our AR 2209 here they also showed 4831 which is a bit slower than 4350 it is our AR 2213 Short Cut I looked for a bit more in my books but could only to find 3 loads for cast bullets with a powder that was obsolete.
Thanks for the info would imr 3031 be a more sutible powder? If so what would be a good starting load for 154gr jacketed bullet? I bump them to .287.
The problem I'm having is the newest book I found with load data for the 280 Ross was published in the 70s.
And the powders are probably not available. Have you looked in Cartridges of the world?
Yeah that's the reloading manual I have it's the 3rd edition. I also have a ideal boom from the 20s with data in it but that's way to old to use haha.
Nothing in C O T W 14th edition either Jim just stated FL = Factory load for the 140 - 150 - 160 to 180 grainers may have something in an earlier version but I would not transpose powders if its an obsolete one as the burn rates may be different. If you have managed to get it working with the powder your using without danger then try minute adjustments with the jump or a different primer but be wary as different primers can cause pressure prob's.
