I could use some reload data on a Sierra Game King ballistic tip (green) 140 grain bullet. Can anyone offer up a suggested powder, amount and approximate velocity for my .270 cal.? I don't have the Sierra reloading manual, so appreciate any suggestions. This would be for white tail, axis, antelope, and mule deer. Or, if a good website for the above that would be perfect!
My first post, so appreciate your help!

H4831SC in quality brass and 210M primers gets 1/2 MOA 200-450 yds. Assuming you're shooting a .270 Win. My grandson's .270 Win and mine like this combo, but obviously not every rifle will shoot the same load well. Good luck

In my Tikka T3 the one with Tupperware stock I use the following and it shoots 0.1-0.3 MOA at 100 yds.
For some reason at 300yds it shoots 3-4 in grouping but that might be me or a combination of me and 7x scope.

Sierra 140gr SBT Gameking .270 Cal - 0.277in.
55.5gr H4831SC Powder
Federal 210 Match Large Rifle Primer
Winchester Brass - Case Length 2.540in
COAL: 3.30in
Muzzle velocity: 2,850 ft/sec - calculated

Hodgdon.com, (shameless plug) powders with higher pressure for maximum loads should burn more consistently.
