JSB Diabolo Exact Heavy .177 Cal, 10.34 Grains, Domed, 500ct

Tried a dozen different pellets in my .177 Hatsan Airtact and this JSB Heavy has the best grouping.

Shipped nicely with foam to prevent damage.

Our Crossman Fury (springer) shoots best with these pellets. Not an easy gun to shoot, but I like it because of how hard it drives these & the grouping is the closest of other grains this size.

Nothing

Prices going up everywhere! Seven to 10 grain pellets used to cost $7 to $15. Hope American debt come down.

Work great in my Marauder

Nothing

Best pellet for Mrod i have found

Shoots great, even at low power setting

These are more expensive than comparable pellets

These are very accurate and consistent shooting pellets. I use them in my Air Venturi Avenger and they shoot one hole groups at 25 yards. I have found that my rifle likes the 10.34 gr pellets better than the 8.4’s. I can’t guarantee they will work as well in other guns but they are great in mine.

Nothing at all

Give them a try

Pellets are very accurate and at a better price point than the competition.

J S B pellets are top tier . They are often used when testing for accuracy in air gun reviews for good reason. I purchased the 10+ grain because the JSB 7.3 grain broke the sound Barrier and made a loud crack when used With my RWS 52 magnum springer. I found The heavier pellet to be a good choice in this rifle. I also recommend trying H&N as well. I own 12 air guns and these two brands are my favorites .

They are on the expensive side but worth
the price .

These pellets allowed me to see just how accurate my Gamo Swarm Magnum Gen3 really was. I bought these and several H&N pellets in the 9 to 10 grain weight class to try, as my gun seemed to prefer that weight. My first two shots with these were flyers, and almost made me skip over them. After cycling through the different options, I said what the heck and loaded up another clip with these. I am glad I did. I proceeded to punch a 0.5" hole in the target with six pellets at 45 yards. I narrowed my choices down to this pellet and the H&N barracuda extreme. The Diablos outperformed the barracudas in a few side by side comparisons. I zeroed in with the JSB Diablo and out 6 shots in less than a 1 inch group at 45 yards, with four of the six in the same hole. The barracuda extreme was precise as well, but had flyers more often. Honorable mentions include the H&N barracuda match, the Sig Dagger, and the Gamo red fire. The red fires are accurate as well, but break the sound barrier.

As others have mentioned, JSB should use screw on lids. One mistake and you will be out of an expensive tin of pellets.

If you are looking for the most precise and accurate pellet for your Gamo Magnum, give these a try.

These are my go to for all my .177 guns. They seem to shoot best for me around the 850-900fps range

Not a thing

most all ready know they are the best
