I've been shooting this ammo for awhile now and have found that it has the best accuracy performance of any of the ammo's I've tested. Shooting them from my CZ 452 I've had 100 yd groups that 8 of the 10 shots can be covered with a dime. Compared to the 17 grain they're substantially more accurate (for myself, my father, and my brother's rifles). We're consistently hitting Prairie dogs at 200-240 yards. The biggest downfall to this ammo is that it does not open up and create the same level of devastation that the 17 grain polymer tipped ammo does. All and All, great ammo!
