They're pretty close. The original Cheetah has an AI type 40 degree shoulder. The Cheetah MarkII retained the original angle, or something pretty close. They are barrel burners! We used a 1 in 10 twist w/50-55 grain bullets @4000+fps. Seemed like the groups got tighter the faster we pushed them!

Accuracy will start to degrade after about 1000 rounds of that though.

Any way you go, they're just plain fun!
