this pellets work great in my new hw97k blackline can cover with a dime at 45 yards after break in

nothing there great

These pellets work amazingly well in my CZ Slavia air rifles 630 & 631 very consistent and accurate .

Pretty Red & White lid.

I know that air gunners have asked for a screw top lid like a lot of other manufactures. I think by now we should realize that they just don't know how. They just don't care as long as we buy what they throw at us. I take the JSB can lids and put them in my printer and copy them on PHOTO paper and then cover it with a clear laminating sheet and cut them out. Use double face tape and adhere them to your empty screw top lids and they last as well as the painted ones. It takes some time but as you can plainly see JSB isn't going to give you what you want.

I have seen several air gunners size the JSB pellets and have found them all over the place with size. I think maybe the only reason they shoot well is the thin skirt and over sized.
I thought I would weigh a can of their QUALITY CONTROLLED 8.4 gr. pellets. ( 8.3 gr.--39) ( 8.4 gr. -- 145) (8.5 gr.--172) ( 8.6 gr. 100) (8.7 gr. 44)
Weighed with Re loader powder scale and checked with balance scale and another brand powder scale.

Most accurate pellet I have found for my Hatsan 95. Sub .300 ten round groups at twenty yards when I do my part.

Nothing

Found that consistent pellet seating depth improved grouping greatly.

ACCURATE, HITS HARD, DECENT PRICE

NOTHING, MAYBE THE PRICE (LOWER)

JSB PELLETS IN ANY CAL (TO ME, MY OPINION) SHOOTS GOOD

The pellets.

Lower the 40% raise in price.

Do not purchase

Very consistant POI and excellent energy transfer when used for ratting or pigeons.

lower the price to increase sales

Im not sure exactly what the reference on the bottom of the tins refers to, 4.52, or 4.53 as it does not seem to correspond to the head diameter. On the sample batch im testing, the head is 4.42 mm, and the skirt is 4.73 - 4.75 . weight is very consistant. They are awesome straight out of the tin, but as I use a resizing tool to set all the pellets for my rifle to 4.55 m to optimise accuracy, im running all the pellets through the tool, just for peace of mind.
The JSB DIABOLO EXACT is every bit as accurate and carry's the extra weight for pest control, over the RWS diabolo flat heads i use for competition shooting.
The slightly softer lead in the JSB shot at the same power level is impacting my steel target back plate and totally transferring it's energy into the target. Excellent for pest control, and would use them for target shooting as well if it were not for the price, and they have out performed all the other brands ive tried for pest control. Glad I did try JSB exact's.

Absolutely fine.

Nothing!

JSB does make a high quality, pellet that most guns like.

These are NOT 4.52mm. Most I checked are 4.5mm! But that is consistent because the 4.5mm are more like 4.4mm as they fit loosely in all my airguns but one, an old Daisy Powerline 1101WS. If you have a Gamo Swarm with auto loading magazine, FORGET about using these, even ones marked as 4.52mm. They will fall out as you cock the rifle. I sincerely wish that JSB would be more accurate in their sizing. The quality is good but accurate sizing is way off.

These are popular pellets but they are skinny and some are so skinny that they feel loose in the breech. Pellets that do not seat snuggly can be flyers.

These are another great pellet produced from JSB. However, in the tin that I received I found the pellet weights to vary from 8.4 grains to 8.6 grains. They grip the riflings extraordinary which produce tight patterns for me at the 25 - 35 yard ranges, but the pattern becomes more oval in the 50 yard plus ranges. I belive this is due to the weight differences from pellet to pellet. I have experienced a lot more variation in other brands of pellets, so I would recommend them. They will produce sub quarter sized groups in the 25 yard ranges out of the guns I tested them in.

At least in the tin I received, I would like to see a little more consistency in weight. They are not to the point of sorting pellets for me and I think JSB certainly has the capability to produce a pellet that is a little more consistent.

Exact is the only pellet that shoots tight groups in every gun I've tried. The 8.44 is an excellent weight for magnum spring powered guns for long distance shots on pests. It's not too heavy that it may blow out a piston seal on your gun while it does helps with penetration past 40 yards. Note the pellet comes in multiple sizes 4.52mm and 4.53mm. The diablo shape is super accurate and penetrates well. This is my favorite pellet of all time and I recommend that you give it a try for yourself.

I would not change a thing, obviously the experts at JSB are exact!

A great article on the pyramdair blog site called "How does jsb make pellets". These pellets are sorted by weight and the scale is sensitive down to 0.0001g (WOW) then swagged to exactly the same size and thanks to one of 22 female inspectors, you can be reassured they are all visually inspected by hand to remove 2% rejects that could have been a darn flier that would mess up that perfect group you were shooting for all day!

I am using them in my Diana Stomrider. At 20 yards, this are the best pellets for this gun compared to others pushed in this order. The 8.44 grams seems to be the perfect paired weight for this gun at the range mentioned. Pellets that I have shot so far, seem to be of a high quality meaning consistent shot groupings and no loading malfunctions

So far there is nothing I would change.

All around good product

I have tried many different pellets in my FX Impact, RWS, Condor, and Daisy 777 airguns, and I always come back to JSB Match Diabolo Exact 8.4 grains 4.52 mm. I use the pellets straight out of the tin, and rarely find any deformed skirts or debris. With my FX Impact, the only flyers I ever get are my fault.

Nothing.

I primarily shoot targets outdoor from 10 to 50 yards. The 8.4 grain pellets might be a little lite for hunting or windy conditions beyond 50 yards.

The lead the JSB pellets are made of is softer than a lot of other pellet brands. Although the pellets come out of the tin in great shape, it is easy to deform the shirts if you are too rough when rummaging around in the tin. Pyramid Air does a good job of packing the tins for shipping.

I've tried these in both my marauder and BSA R10 and past 25 yards they were not as good as my 10.34

These pellets I do know work in a bunch of guns. One worth a try.

Very good accuracy in my CO2 rifle.

Very consistent product that preforms well in most of the air guns I've owned.

As always price is a consideration. Lowering it by 33% would certainly secure the majority market share across the majority of the products in all price points.

All the JSB products I've tried are produced at an above average standard of consistency. However, like all pellets there is substantial pellet to pellet variation particularly in weight. Best results will come for those that weight and sort each tin into at least two weight categories if not more.

Very consistent precision in my Crosman 2300S.

Nothing

Do not let a few dollars more for these and other high-quality pellets deter you, if you enjoy consistent precision in your target shooting when shooting bullseye rings.

i've been purchasing jsb exacts since they first came out and never looked back...they are incredibly uniform, each fits as the previous one and they are clean...i use them in my tx200 and rws54...as long as i'm shooting and jsb doesn't change the recipe i'll be using the exacts...end of story...

not a damn thing...please...

both my airguns are 177cal...

Quality of pellet..

Nothing..

Will have additional comments when I get too shooting them in my Crosman Silhouette and 2100..even iff not accurate isn my guns they should perform well in others.

Great pellet. All of them shoot the same. Worth the money for sure. This will be the pellet of choice from now on.
