Things I liked:

I tried these in my Gamo Swarm Fusion gas piston air rifle with great success. They loaded well in the Gamo 10 X mags and I remember the first shot was a bullseye at 40 yards. Knock down power was amazing and I call these "Thuds" because of the sound they made dispensing pests.

Things I would have changed:

Wish they were 300 count for the price.

Things I liked:

Accurate in all my springers. Benji Prowler 21 ftlbs. Beeman Mach 12.5 30 ftlbs . RS-2 Beeman x2 17ftlbs. I use treated 2x6 backstop pine. Pellet penetrates to cover the skirt in all gun(10meters). Knockdown is impressive on jackrabbit..and foxes. Higher velocity than Rabbit Mag IIs..more accurate...less hard alloy though....(I have do more test before head-shot pigs...although at 10 meters an eye shot is assured 100 percent.) I only use the Mach on pigs. All guns .22 cal. Rs 2 can convert to .177..but too accurate to mess with that. You get .25 cal. Results at this weight.knockdown. with.flatter trajectory.cost. variety of pellets. Availability.etc.

Things I would have changed:

If it remained accurate...maybe offer a HARDER LEAD ALLOY version specifically for hardtarget penetration...bone smashing. Our possums are HUGE!!! due to favorable climate last couple years ALL game teeming in west Texas.

What others should know:

Since I use springer/gas piston guns only..I limit my use of heavier pellets to extend gun life.The Mach 12.5 max out at 27 gr.hn slugs.217s 30 ftlbs...but is optimized for 18-21gr.weights. The [email protected] 16 gr. Rs 2 16 gr. The weaker guns give good performance with this heavy and can be replaced..but not the Mach! try and find one.

      they may be too long for the magazine. They can be single loaded.

  • Carl from USA asked:

    I have a Gamo .22 rifle with a 10-shot rotary magazine. Are these pellets too long for the magazine?

    • Mark from USA answered:

      Probably. We have not tried them.

  • Rojohn from USA asked:

    I thought these. 22 25 grain monsters were redesigned... When will Pyramyd send out the new ones?
