Things I liked: Penetration is INSANE! Rip right through a raccon @ 976fps. I think that the tip must separate and then tumbles, as that coon had a nickle sized exit hole in him. I did have to adjust my zero with these (HIGH) however since I've been tack driving.
Things I would have changed: Bigger tin 500 would be great! Make them just a tad shorter. They work great in my Sheridan SS and Archer QB78. How ever they are to long to fit into a crosman rotary clip. Wanted to try them out in the 1077 but their just to long.
What others should know: According to the croni I pushed and additional 100fps both my QB and SS!! And quadrupled my penetration over H&N Neue's I've been using.
