Been told it is too slow, but am getting good results with Reloder 17 (but can't find more) which is pretty close in burn rate. I have a couple of lbs of Staball 6.5 so maybe it will work. Need some data.
(IMR 4895 has been a disappointment in this combo, W760 was a little better.)

it is on the slow side . a max pressure load will be at 112% case fill . that's more than I care to work with .

I like to work around 105% case fill , at max PSI . here is a powder list that might help you decide on where to go next , it looks like RL17 was tops for velocity in this combo .

Bullet : .308, 178, Hornady ELD-X 3074
Useable Case Capaci: 44.753 grain H2O = 2.906 cm³

Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 62000 psi, or 427 MPa
or a maximum loading ratio or filling of 115 %
These calculations refer to your specified settings in QuickLOAD 'Cartridge Dimensions' window.
C A U T I O N : any load listed can result in a powder charge that falls below minimum suggested
loads or exceeds maximum suggested loads as presented in current handloading manuals. Understand
that all of the listed powders can be unsuitable for the given combination of cartridge, bullet
and gun. Actual load order can vary, depending upon lot-to-lot powder and component variations.
