I dont see why they wouldnt be,. How well do they group out of your rifle though?
The reason I ask is, I have a Win. mod. 70 and I for the life of me I cant get the Nos. to group under a 1 1/2 group at a hundred yards. But on the other hand the Swift A Frames are grouping about a 3/4 group at a hundred. If they group well in your rifle then I dont think you could buy a better factory round then those.

Just a thought
