Air Venturi Dust Devil Mk2 Frangible BBs, 1,500 ct.

Nothing

Make without a sprue so they don't jam.

These bb's jam in EVERY gun I've tried them in. I only wish Pyramid would give me a full refund. Don't waste your money on these.

Many would fragment as designed.

Over 40% of those few shot, either jammed in the magazine or ricocheted back like I was shooting steel bb's.

These do not work in my CO2 Colt Defender. They constantly jam or fail to designate. Maybe they'd work better out of a longer barrel revolver or rifle.

Everything shoots great no rickoshy

No ricochet

Came free with an order, rolls outta the barrel in several of my guns... Even with 700 fps they don't "turn to dust" shot into a pellet tin at 10 and 20 yards... They chip, but do NOT "turn into dust" Glad they was free...

Ummm, make them less hard, so they will turn to dust, that'd be an awesome squirrel or pest bb iffen they did brake up after hitting pests, they'd be deadly then...

Roll outta barrels without magnets bolts, not even close to the real bb size, they look like a UFO shape...
Don't turn to dust, wouldn't even work in the pistol they came with, that's bad lol!!!

Shatters reliably against things it can't penetrate with sufficient power/velocity behind it

Feed poorly in co2 pistol magazine and often tries to jam or spits out part or entire magazines worth before loading. The slightest diameter increase or more consistent sizes, some change to prevent them going past before they're meant to, normal BBs do not have this issue

Don't always shatter into dust, sometimes stay in small but low energy fragments. Experienced this while testing/experimenting at 5-10m, felt small bits gently hit my pants below the knee, good coverage eye protection encouraged for close range

Was hoping to at least get marginal accuracy and the higher FPS. Like others have said, they do not cycle in magazines very well, and accuracy is abismal. So, nothing I like about these BBs and would not be purchasing them again.

First, lose the center band on the BB. I'm sure they can be manufactured completely spherical. That alone would probably solve the magazine feeding issues as well as the subpar accuracy.

Stick with traditional BBs unless your objective is to delete CO2 powerlets. These BBs are useless otherwise

Well not much,they didn't work in my magazines, so I can't give a review

Uniformity, be true 4'5mm

They do turn to dust

Size and texture

These are not a uniform shape the only gun I can use these in our single shot. They bind up in multi shot and won’t come out.

They shoot well when i can get them to feed from my magezine.

Need to be 4.5 mm.

Still good to have on hand.
