H&N Excite Prometheus .22 Cal, 9 gr - 200 ct

Have not tried these in a lot of guns yet. With the Hammerli 850 at 10-15 Meters you can hit the pop can but you will not be able to do sub 1 inch groupings like with lead pellets. Whatever they hit they hit hard and penetrate deep because of the increased velocity and metal nose. I have only tried a couple of lead free .22 pellets so far and these have worked well compared to the others that I have tried.

Pros
Lead Free High Velocity Deep Penetrating

Cons
Accuracy not as good as lead pellets.
