JSB Match Exact Jumbo Diabolo .22 (5.5mm) Cal Reviews
Tell us what you think
Accuracy!!!! If you visually compare these pellets to others, you see a very high consistency of the finish. No burrs, no dings, no rough casting surfaces. As a machinist of nearly 30 years, that stands out to me as very important for consistent accuracy shot after shot. I shot these through my Beeman break barrel and it was a game changer. Finally hit the lucky combo.
Nothing
These are produced in various weights. My next purchase will be to try them all. Half the fun of this sport is hitting the perfect combo and then taking out a tree rat with a clean single hit at 30 yards. No brag here just happy I can turn a "toy" air gun as some would say (no not here) into a viable humane varmint control weapon without causing a fuss for the neighbors
I didnt, they shoot extremely large groups in my Walther talon. These 5.5 pellets are to small in diameter.
Make them in a 5.52 instead of 5.5 inches. They shoot extremely large groups in in my walther talon/Hatsan 125
These pellets are smaller in diameter VS most pellets. They measure 5.5 vs 5.52 so if your bore slugs larger like my air rifle they wont fly consistently. Its like throwing a hotdog down a hallway. The 5.52 jumbo heavy 18.13 grainers shoot the best in my rifle and the 5.52 RS are a close second. These 15.89 grainers are worst grouping pellets out of 15 different lead pellets I tried. Even cheap daisy and Crossman pellets shot tighter at 23 yards than the JBS 15.89 grainers.

Verified BuyerPyramyd Air is like no other place I've had the privilege of purchasing all my airgun needs. The staff is amazing, and I love watching Rick shoot some of my favorite air rifles. And the prices are always on point, and often below what others sell them for.
Absolutely nothing. You guys are doing an amazing job!
You can trust Pyramyd Air for all your airgun needs (as well as your wants).
With my Avenger, ten-shot one-hole groups at 25 yards at 1200, 1500, and 2000# regulator pressure.
Nothing.
I wish that I could buy them at the local stores.

Verified BuyerSo far the best shooting pellets in my Diana Bandit PCP. As always, very well packaged by Pyramyd. I like screw top cans also.
Lower cost. I would also like a WC version in this weight.
Skirts are thin. Look at them before loading, if deformed, use the head of another pellet to iron them out. Your groups will thank you.
Shot consistency. So far have shot many 5 shot groups with repeatability and able to cover with a dime from 23 yards. So will chrono for consistency and move out farther to 40 and 50 yards to see how it maintains.
The Gamo 10x maximum G2 riffle that I have seems to like this pellet the best so far
Excellent pellets, seems to be one of the two best in this caliber for my Hatsan Quest and my Benjamin marauder; the other one the JSB 18.13 gr.
Nothing
No
Very very accurate. Perfect for pesting or targets. Great all around pellet.
Nothing
Purchase these for great shooting.

Verified BuyerCan be repurposed for musket balls
While attempting to load a 10rd magazine, for every 1 "barely usable" pellet, 2 were set aside because they were deformed and/or poorly formed on skirt. In an order of 4 different brands, this was the only one with quality issues.

Hands down the most accurate pellets for my Komplete and my Zeloes so far, Nickle size groups at 25 and quarter size at 50 yards. I didn't realize that pellet gun accuracy had gotten to this stage. Haven't owned or shot a pellet rifle in 40 plus years but I really like these two.
