Most factory ammo will do better than that. I agree that something else is wrong with two different brands of ammo doing that bad.
The 300 Win mag is a very good round and something else is messing up the groups.
I would start by changing scopes if you have another one, if this does not fix it I suspect you have a barrel problem or a bedding problem.
If you have not bedded the HS stock don't assume that the bedding block is all you need because
if you loosen the action screws just a little , you can move the barrel back and fourth and rotate
the barrel clock wise and counter clock wise. (This is why you need to bed it).
