These JSB Ultra Shock are the new alternative to the Predator Polymags which are great hunting pellets but may not fit in your magazine. These and the Polymag Shorts are great options to look at for magazine fed rifles. These carry some extra weight for those high powered rifles. The enormous cavity on these expand immediately on impact dumping as much energy as possible. These are no joke, you won't see any prairie dogs or Squirrels laughing!

*It’s all a balance between power, weight and twist rate. If you get those right then you will see the results!*
