Air Arms Diabolo, .177 Reviews

These are good pellets and shoot well in my Diana guns.

Quality. Consistency. Clean in the tin. Good design for distance, but also good at 10 yards.

Nothing.

Accurate in short barrel PCP pistol. Accurate in PCP rifle at 25 yards.

These are incredible pellets that are worth the price. Rifles that use rotary mags tend to be very picky about ammo and it can be difficult to find pellets that consistently seat properly and don't require extra effort. My Gamo Swarm Fusion Gen2 and Umarex Fusion 2 eat these flawlessly without any extra input. The only comparable ammo I have found is RWS Superdome, RWS Supermag, and H&N Barracuda Match. The latter two are much heavier rounds, however.

Nothing. This is product is top quality.

The Express version is just as good if you want a light rifle round. Pistol rotary mags tend to want to be fed proprietary ammo.

Expands extremely well.

I shot a copperhead with these pellets and it went in the snake with a .177 hole and came out with a huge hole through its guts. Didnt suffer long.

Well made pellets. Accurate.

Highest level of quality, consistent weight, accuracy off the charts. Excellent for small game, pests.

Longer skirt than the H&N field target trophy

These are good, but, don't seem to be quite as accurate as the same pellet sized 4.52. We have tried both sizes in 6 different guns and all but one showed a noticeable difference at 50 yds. I never would have thought that small size difference would mean very much, but it does.

Guns used were, TX 200---Sig Sauer Asp 20----RWS m36---Walther LGU---Gamo ACCU---and a Walther Terrus. The Gamo didn't show any difference in group size.

This is a hard review to write. I thought I really liked these pellets but now am not so sure. After purchasing a QB Chief I went on a quest to fine the pellets it liked best. After many different brands I tried the AA Diabolo .177 in 4.51 head size and found a pellet that consistently gave extremely small 5 shot groups (3/8" inch or less) at 25 yards with almost no flyers. I was very happy with this so as the first tin was getting low I ordered 4 more tins. Since opening the first of the new tins I can no longer get those consistently small groups. Now I am lucky to get a small group with most being over 1/2" and fairly often getting flyers that open up the group to about 3/4'. What happened? Seems like AA has no consistency batch to batch. Now I've got close to 4 full tins of a pellet that makes my gun shoot nothing special and will have to start the search for a good consistent shooting pellet again.

Make consistency batch to batch better.

These pellets feed accurately in a TX200 MkIII Air Rifle.

Nothing

Clean pellets that shoot OK, but not great in my TX200.

The tin says that these are 4.51mm heads, but my measurements with my Pellet Gage indicate that the majority of the pellets have a 4.53mm or larger head. Returned the 3 un-opened tins to PA (Thank you!) and ordered JSB Exacts. The JSB Exacts actually have a 4.52 mm head, just like it says on the tin, and shoot great in my TX200.

If you air gun like pellets with larger heads, these pellets may work for you.

Impressive accuracy. 6 to 10 shots in the same hole @ 18.5 yards. No jams even while learning to use the Gauntlet cassette.

Price of course

Supposedly repackaged JSBs, I find these 8.44s and all the AA branded versions to shoot more accurately with fewer flyers than JSBs...with this slightly heavier weight I give up a little velocity to gain a little less wind drift.

Twist lock type tin...PRICE.....yeah yeah...a European product...but really no one in the USA can make precision pellets and a profit.....airgun mysteries of the universe....

Yeah....all you $1200 to $2500 pellet gun owners out there....1) no matter what your backyard fantasies are....these are still just pellet guns.......2) you are totally at the mercy of whom ever makes what is shooting best this time around.

Consistent sizes. Prosport love em

Screw on tin

Try em

Very accurate and have not found any deformed pellets in any of the tins I have purchased!

Nothing

Give these a try in your air gun and expect accuracy!

I purchase about 50 tins of these a year and they have always been good to excellent quality.

The last order (Nov. 2015) of 20 tins are bad with many malformed skirts with swarf inside the skirts. Some of the tins have two distinct colors of pellets; about half are shiny as usual and half that are a much darker in color with a dull finish. These will probably get sent back as they aren't what I expected... too bad, they have always been better than anything else for me in the past.

These are outstanding in my R9. Wow! For many years I used CPL for excellent accuracy in my R9, and the average groups of AA 4.51 look like the best groups of CPL.

Nothing.

My R9 seemed to only like CPL. It does not like AA 4.52, JSB Exact 4.52, Beeman FTS, but it loves these AA 4.51. I'm really blown away at how good they shoot. Looks like PCP groups.

Pellets are priced very well for quality. These are the most accurate pellets for my 1986 HW77k.

Nothing

The skirts are thin and you will have some unusable pellets. Overall the quality is very good. Chrono at muzzle is 755 average and at 45yds 580 average with very low spread. Just some info

This pellet is a new best friend in .177 caliber. Very uniformed pellets, and superb packing as usual from PA.

Screw on lid would be nice. It would also be nice if you do not run out of these pellets again. I had to wait over 30 days while on back order.

H&N FTT 5.51 head are really good pellets, but I now see I have wasted 100s of dollars. These are the best pellets for all my .177 caliber rifles. While the H&N pellets benefit from lubing, these pellets do not need a lube. I own a 20+ year old UK Tomahawk, CZ 631, and a Silent Cat. After I get stocked up on my .25 & .22 pellets I plan to spend $150 just on these pellets. This is my go to pellet. :)

PA was out of JSBs and I was told these were a very good replacement. How true as they have proven to be "very" accurate in my HW97K

nothing

try them you'll like them..

Very little or almost no flyers, well made. very accurate pellet in my Umarex fusion. .127 five shot group @ 20yards

Nothing at all

My results are base on my gun.. Its always helpful to the next person if they know what gun you are shooting...
