Will these function properly in the Gammo Swarm Magnum mags? Will the mag rotate/feed without jamming?
How well do these pellets work with the Beeman Teton Gas Ram?
Every barrel is different, but they would certainly be on the short list to test if you're looking for a good hunting specific pellet
Are they good for groundhog?
That depends more on the gun you're shooting them out of than the pellet itself
Are they good for pest like groundhog with a Benjimen trail np2?
will these pellets fit in the Benjamin marauder 10 round clip? has any one tried them
The Predator Polymags fit my P Rod 8 shot magazine no problem
Too long, just like the polymags.
What's the accuracy at 50 yards and starting velocity of 800 feet per sec?
Depends on the airgun.
