The 270 WSM is one of the better shooting short Mags and

which ever one your rifle likes will work, the 130 grainer are

better for in my friends rifle, will shoot flatter for with in the

normal shooting ranges. Good luck on you hunt!

First I'm going to assume that you have a 1 in 10 inch twist rate on your barrel which is probably right.  A light bullet will have a flatter trajectory and a higher velocity than what you will get from a heavier projectile, but the heavier projectile will deliver higher terminal ballistic values (a very good thing when developing a load to shoot live targets with) much farther down range.  I would recommend loading heavy for caliber (140 to 160 grain bullets = high sectional density) that are either core bonded, or mono metallic, with the highest ballistic coefficient that you can get.

 

Hodgdon Powder Co. website has a section devoted to recommended powder charges for various calibers including the 270WSM.

The 130 grain bullets work best and shoot  well for that type of game.

 guess I have not hat mine long enough to start working up a load but I do like the way it is shooting factory loads, both the win balistic silvertip (130) and the accubonds (140) group alright... under 2 inches while shooting off my arm... I will know more in a couple weeks after I start loading but I would not be afraid to hunt with it now using either weight bullet.
