New to loading for 270 Mannlicher

[Zman]

I am new to reloading and intend on using a 270 Mannlicher Schoenauer for White tail in Wyoming. I have Nosler 150 BTs and not sure about which powders and loads to use. Nosler Ballistic room lists IMR4350 and H4831SC which defers from the powder recommendations in the Winchester manual. Any recommendations or advise for this beginner would be appreciated.

H4831 is the powder the 270 win was made famous with useing 130gr bullets. Both it and H4350 are excellent in the 270 with all bullet wgts. Winchester of course is going to recommend their powders, and Hodgdon theirs. The fact Nosler goes with H4831 should be a hint at which is possibly the better choice.
The powder I`ve had best results with is R22. The velocity is right there with H4831 and accuracy is better in my rifle.

Thanks for the re-direction. Seems I misread short magnum data for the 270. Winchester does list H4831 for Nosler 150 BT as well as 4350 and RL22 for the standard 270. I will start with the H4831.
