<PrimeTime>.280 with H4831SC???
I have loaded up to 58 grains of h4831sc in my 280 and was wondering if anyone has gone higher than that? I am sticking with the 140 Ballistic Tip and get around 3,000 fps now but think I could maybe hit 3,100 and still keep the accuracy. Right now I am at the max loads in my manuals but do not have any pressure signs. So is it possible to go higher with this powder?

<Deafdog>Hi PT
ADI in Australia makes H4831sc, in oz it's named AR2213sc.
In the ADI Handloaders guide they have
140gn 58.5gns for 2927ft/sec(24"barrel) as a max load
for what it's worth.
Regards

<robbnsc>I have found each .280 that I have owned (3) to be very different in max. loads for the 140 gr Nos. B-tip, particularly with IMR4350. I think that you are near the max., but you are on your own over 58 grains.
