It's far & away the most accurate factory ammo in my rifle. Between my buddy's rifle & mine, those 173's have accounted for 5 or 6 hogs, from 5 to about 100 yards. The same buddy took a nice 10 point white tail with them last year, & reported finding a perfect mushroom under the hide on the off-side.
The accuracy was good enough that I carried them on an elk hunt, but I ate the tag because I was in BC, & couldn't get on a 6pt during that trip. I was drawn on an excellent 5x5 bull, posing broadside for me, for every bit of 60 seconds. We just couldn't make out a 6th knob anywhere, so I never pressed the trigger.
Some may question the bullet toughness, & that may be legitimate. However, I figured that 173 grains going at leisurely 7x57 velocities ought to hold together well enough, even if one hits bone.
And you're right: for $15 you really can't go wrong trying them out.
