Thanx fer the links, Busta. Still didn't find any "grains equivilant" anywhere, so I'm going to assume that they are 50 grainers. (But assumptions can get you dead too!
)
From the articals you provided links too, I'd be inclined to say, after trying to disregard "gun writers hype" that tends to to crop up with any new product, that they are a fairly good product with a low SD. Which would tend to be good fer accuracy, but I'm not going to run back to the store and grab a box. Because I already get 'minute of kill zone' accuracy from my old Traditions inline, loaded with loose BP.
