Page 3 - JSB Exact Monster, .177 Reviews

I won a .177 Umarex Fuel last year at the Texas Airgun Show in Mansfield Texas. Iike shooting this easy to dock break barrel but had not found a pellet it liked. I found the JSB EXACT Monster I. 13.4 grain. My 30 yard groups went from an 1 1/8" to 1/2" and sometimes less. Great pellet

I cznt think of a thing.

The more you shoot these in your airgun the more accurate your airgun becomes.

These are the most accurate pellets I have ever found for my .177 Marauder.

500 per tin at the same price. Screw on tin lid.

I am shooting these with a Benjamin Marauder with a Marmot Malitia barrel at 825fps. I had been using the 10.34 JSB's and tried these 13.4 grain. The down range hitting power is great and at 30 yards I get consistent sub 1/2 in groups with 10 shots. Most 5 shot groups have 1 slightly enlarged hole. The only problems I have is that when loading the 1st pellet into the clip I sometimes have to lightly push it into the clip to get it under the rotating top piece. Not a big deal. All the rest of the pellets load into the clip as normal. I'm loving these pellets. Just ordered 4 more tins.

I own several air guns and like to have a good variety of pellets to choose from to select the best pellet/gun combination. 7

You can not go wrong with JSB,s.

The jury is still out on these as both my .177's are HW 35's. I have to shoot them thru the Chrony to get an idea of the velocity. If I can get 700 fps+ out of them then they will be comparable to CCI CB Shorts or Longs which will make them great for pest control. From an R1 in .177 these would be serious long range pellets. My R1 is .22 Cal and The Monster Pellets weight twice as much and hit hard..

nothing

You need a powerful airgun for these.

They are hard hitting and accurate and my gas piston Gamo loves them a lot. ..

Nothing

They're really close in weight and all chamber easily

Great .177 pellet! They are the best Pellet for my Swarm, groups are tight out to 25yds, pellet on pellet at closer ranges.

Nothing

Recommend at least trying these. Every barrel shoots differently. You might find a winner in these!

Great pellet!! I use in my TR-77, RWS 350 magnum compact, and my Benjamin titan.

nothing.

Obviously use in higher powered break barrels or PCP.

Every pellet was in perfect shape. Very accurate pellet for .177 cal guns!

Nothing!

Highly recommend these!

Hand Weighed the entire container. Individual weights ranged from +/- 12.9 to +/- 13.95. Split the pellets into three groups. Test group averaged +/- 13.43 to within .05 grain. Lowest weight group averaged 13.28 with a maximum variance of +/- .3 grain. The heaviest group averaged +/- 13.60 and varied +/- .35 gr. Shot from my air arms S-510, the 10 shot test group averaged 879 fps 1' ft from the muzzle on my 18 yard indoor range, and 793' fps at 18 yards, providing muzzle energy of 23.06 and 18.76 ft lbs. respectively. The BC calculated out to be .0235. The 10 shot group measured 1/2" at the widest point, creating a very tight group.

I found these pellets to be very uniform, to feed from the magazine very well, and to hit with authority.

Even though these pellets are heavier, the JSB Exact Heavy pellets at 18.3 grain actually had a little higher energy level and shot even tighter. I am anxious to get some nice weather to move outside and try some 50 yard groups.

This is a correction from my previous review. I was on the wrong pellet before. These are very good the size is consistent, they fit well in the breech they shoot very good and they're fairly accurate. Weight and shape are good.

Nothing.

I have a GAMO Magnum .177. These fit nicely into the breach. They work good for this gun.

Weight.

Make size consistent.

I have a Gamo Magnum.177 and so far only about one out of ten of these will barely fit into the breach. Most of them are too big to even get the head into the breach. They do not work good for this gun.

Great cylindrical pellet, good knockdown power for a .177

Would not change anything.

Hi impact Good weight

Would like to see a hollow point for hunting

Retains energy for that long distance shot.

Like the JSB sorted premium match boxed 8.44 & the 13.43 should also be sorted out because it shows very good potential.

Currently the JSB brand rules most of the airgun competition.

Shot from an Air Arms S500 Extra and an Daystate Huntsman. These are the most accurate pellet from both guns. From the S500, average of four, five shot groups was .209" CTC. From the Huntsman, (same shooting session) group average .228". Conditions: 30 yds, benchrest, 1-2 mph breeze, temp.65 F, 200 - 175 BAR gun pressure. This pellet is consistently the best grouping with the fewest flyers of all that I've shot.

No

A steal at $12.99

Shot from an Air Arms S500 Extra and an Daystate Huntsman. Most accurate "heavy" pellet from both guns. From the S500, average of four, five shot groups was .332" CTC. From the Huntsman, (same shooting session) group average .316". Conditions: 30 yds, benchrest, 1-2 mph breeze, temp.65 F, 200 - 175 BAR gun pressure.

Screw on lid would be better.

These are the most accurate hunting pellet from both guns mentioned. They group in virtually the same point as the JSB Exsact Heavy and Air Arms Field Heavy pellet making an easy transition from target practice to hunting. Excellent for a .177 hunting choice.

This pellet is very accurate in my Marauder. In fact, it is the most consistently accurate pellet that I have tested in my Marauder. I have tested some RWS, H&N, and Beeman hollow points, JSB, Crosman, H&N, and Crosman domed pellets. My rifle likes to start at 2800 psi and shoots well down to about 1950 psi (42 shots). Pellets are pretty consistent for size. I measured 16 pellets from the tin and found the average head size to be 4.476mm with a standard deviation of 0.016mm. The skirts were an average of 4.621mm with a SD of 0.045mm. I have shot a couple of tins so far and all perform well. I think I have only had a couple of fliers so far. This will be the pellet I stick with for my Marauder.

Nothing really comes to mind - a good pellet.

We always want things to be less expensive but I think they are priced about right for what you get.

Quantity, consistency, cleanliness. Good energy at the muzzle, and good energy retention past twenty-five yards.

Not anything I can think of, other than, perhaps, the tin's top could be screw on.

These pellets are a fantastic combination with high powered break barrels, and do well at both closer and longer distances (past thirty yards). My Ruger Air Magnum is spitting these bad boys at a max. velocity of 894 fps, or just a few feet per second off of 24 fpe! At twenty yards, energy is still at 20 plus fpe! The pellet fits snug, but not too tight, and attenuates the violent recoil of the RAM powerplant. With these pellets, my .177 RAM is reaching, and surpassing, the energy delivered by my .22 cal Octane!

Easy loading in all guns tried. Remarkable energy retention at distance. Pellet consistency (finish, weight) and accuracy.

Can't imagine improving this accurate powerhouse.

Despite 13+g weight these shorties stabilize in typical .177" twist. So far the most accurate in new Benji NP2 and Gamo BC Bull Whisper, both within first 200rds OOB. We chrono'd at 15 and 30 yds and calculated NRG. >19 ft/lb retained at 30yd and 1" groups in either gun!! btw, extreme spreads and std deviations bely ability to group well. (Will test at greater distances in a future session)
I have to re-order so we can test (& chrono) these in our now-shelved, humble Gamo Shadow 1000 springers. Expect to hand over a tin to anyone you encourage to try them and have to order more for yourself. (Next 'coon spotted had better wear a helmet. No doubt about potential penetration on such vermin.)

Shipped wrapped in foam and no dents in tins or pellets.Great for brake barrel guns.will slow down them high 1100 psi and higher rifles.

Nothing
