SIDE BY SIDE: 30 CAL JSB and 30 CAL JTS​

I have been testing and comparing these two brands of ammo for several weeks and want to share my results with you guys. JSB is one of the leaders in air gun ammo sales. There is a video worth watching that shows their operation. They produce millions of pellets. The vid runs around 49 minutes and if you have not viewed it I highly suggest you take time to learn what an operation they run. Link for the video:




JTS is a new comer to pellet production and making a giant splash in a very short time. I don’t know of a video posted of their production facility, if there is one I would like a link to it . I either read or heard that Bob Sterne (on the GTA and other forums) had input in the development of the 18.2 grain .22 cal ammo and the center of gravity had been relocated. I have not heard if he was working to develop the .30 cal also.

DISCLAIMER: This comparison was shot with a chocked barrel. Your results may be different then this post if shot from an unchoked barrel. Tom, the owner of American Air Arms built the Evol to shoot JSB at around 830-900FPS. Some owners have had success with slugs but it means regulator adjusting and other tweaks.



Test Results and other insight

Price, always a consideration

The last order of JSB from PA was 4 tins. Get 1 free and pay for 3. Use promo code and get 10% off. Add taxes and shipping and total ran 68.38$. 600 pellets at .114Cent per.

Order of 4 tins of JTS were 60.95. The buy 3 get 4th free was available but no promo code, maybe in the future (I hope.) 400 pellets were .15cent per.

Not much difference but it adds up in the long run.



Quality Control

JTS has nailed this! My plan was to weigh all 4 tins once they arrived. The first tin was weighed and 96 were spot on at 45.1 grain. 1 was 45.2, 1 was 45 and 2 were 44.9. I didn’t bother to weigh the other 3 tins.

JSB has been going down in quality for some time now. In the past a spread of 44.2 to 45.3 was a good tin. The last large order of 10 tins (1500 pellets) were off the chart in actual weight. They ran from 43.2-45.9. Why are they labeled as 44.7, there were not very many 44.7 in the total count. The highest concentration were 44.9-45.4. Nod goes to JST for QUALITY

Chrony Numbers

JSB JTS

Avg FPS-890 Avg FPS-904

ES 5.72 ES 8.61

SD 2.14 SD 2.44



Measurements

JTS—Length .375” Head diameter--.3005” Skirt--.305”

JSB—Length .375” Head diameter--.3015” Skirt--.307”

My thoughts on the lower avg speed has to do with head size. I can feel a difference when closing the chambering the JSB. It takes a little extra push to seat. I believe the tighter fit adds a bit more friction and thus the slightly slower FPS.

I hope this is helpful to someone, I will continue to test. I really like the thought of never having to weigh another pellet!

I have attached photos of several groups shot side by side on the same morning. Both were under 1 inch CTC. Also, I placed a 100 yard target used for the GTA NUHC at 125 yards just to see what I could do.

Turned out to be pretty dang good. I plan to share this post on a few other forums so you may see it again somewhere. Thanks for reading my post!

20 ft up in my back yard I see this fatboy hanging out on a limb eating my invasive vines in the back yard.

... I go low.

As the photo below shows, this is how low I set the regulator on my .22 Ghost Carbine. Because the small, almost unreadable Huma gauge is notoriously inaccurate (Come on, BRK/Daystate -- stop cheaping out on parts on these guns for the price you charge for them!) compared to a MUCH bigger gauge on my compressor that gives a more believable reading, it registers around 20 - 25 BAR higher than the segment at which the needle is pointing, so the plenum pressure would be a more realistic 50 BAR or so. Anyway, with a power setting of "5" on the wheel, I'm shooting 14.3-grain CPHPs at 9 FPE (535 FPS) and I get around 320+ shots with an extreme spread of 20 FPS (over the entire 320-shot string) for backyard plinking fun. Anyway, just wanted to share.

common curiosity if your left feed back , Is it really hard to do the same??? Am I Wrong???
should be allowed to delete feedback since some are one way

Is there a source for actual size air rifle silhouette targets set up to hang vs knock over type?

Perhaps not looking in right place, but I have found lots of handing targets of other shapes, but not the actual silhouette targets.

So I went to pump my gun and I went to connect the cables one was connected one wasn’t the one that wasn’t hit the bottom of the compressor by on/off switch and made a tiny spark so I shrug it off and connect the other cable and the compressor turns on but the red off button doesn’t come on and I’ll try to push start and it won’t even pump so it’ll turn on but no off light work start light don’t work and buttons doesn’t work someone please help me out

Anyone have a dreamline bottle adapter they are looking to sell ? Shot in the wild.

Still trying to build monster Af condor.

Meant to go pesting this morning but went on a sweet hike with my wife and pup instead. They then granted a few hours to go out and punish the flying vermin after the hike and lunch. Took seventeen shots, missed twice, once at 64 yards (wrong wind hold off), second time while trying to line up a double at 40 yards. Most kills from 25-35 yards, gimme shots for the Pathfinder. As you can see it’s a crowded house, so judicious shooting at all times.

NOTHING wrong with them, just going smaller.

I spent two days at my brother-in-law farm doing some pesting with my new 25 cal xr sniper and Notoes with night vision atached. Shots on starlings and sparrows were from 50 to 125 yards and one groundhog at 75 yards with the sniper. Shot at least 80 25 grain jsbs in two days. I am guessing a 75% hit ratio. Hunted one night with the notoes . To many rats and mice to count between hog pens and chicken house. Can't wait to go back...

Windy day low shot count but I can took this postal, that I share with AGN friends

Gents,

Those of you who pay any attention to the occasional drivel I post know that I am a big fan of the Brocock Sniper platform. Given this, and the fact that L. Leon had pulled ahead of me in the Ultimate Brocock Fanboy competition, I quite logically concluded that I should have another one, lest ol’ L. Leon run away and hide with the fanboy title. As the new Sniper Sahara was making my sticker peck out, I reduced one in .177 to possession, courtesy of the fine folks at AoA.

After some thought and a few hours at the lathe and mill, I had a suppressor machined up and ready to go. And as I LOVE the power range, my new toy was topped off with a Swamp Fox 2-12 power scope with the MOA reticle. After a few hiccups and a flurry of pellet testing, she was shooting dots with the JSB Exact Monster Redesigned. It was time to hunt.

Alas life, as it often does, got in the way for a spell and the Brocock languished in the dark confines of the gun safe with its brethren. It was a shame. Maybe even a crime…

But nothing will make a man forget his obligations faster than the appearance of ground squirrels around his locale, in this case my neighbors pasture. Tools were dropped on the spot and chores were forsaken. The water heater could continue to leak. A Brocock jihad was in order.

The below is the result of the Sniper Sahara’s first two trigger pulls on live game, one at 48 yards, the other at 53, both shots right in the hard drive.

The Brococks continue to impress.

UPDATE:
It looks like the moisture I was noticing was from water that had accumulated in the fill hose from my 100cc Portable Air Venturi Tank. This is how it happened: I usually have the tank sitting up on a workbench, while the compressor is down on the floor. So as the water condensed inside of the hose it would flow down to the compressor's moisture reservoir. Every time I had filled the gun in the past, when I was done filling and I bled the line, about 1/2 tsp of water would come out of the compressors moisture reservoir.

During the last couple fills I was using the compressor in the field and it was being powered by my car. So I stupidly had the compressor sitting up on the car and the tank was 4 feet below on the ground. So all the water that was condensing in the hose was flowing toward the tank instead of the compressor. Thinking back I remember noticing that I there wasn't any water coming out of the compressor when I opened the bleed valve. All that water was still in the hose.

I detached the hose and there was about 1/2 tsp of water inside. I dried it out and now I'm not noticing any water in the quick connectors after filling the gun, or when bleeding the line. I disassembled the gun, bottle, and air tank, all were completely dry and showed no signs that there had ever been any moisture.

Next time I'm filling in the field using my car for power I'll put the tank on the roof.

I made an air filling station with a coalescing filter in between the compressor and tank. There a lot of debate if a filter is necessary, but I figure it can’t hurt.

Thanks again for all the help guys.

==============
ORIGINAL POST:

I just realized that the air used for the last several fills/top-offs of the 500cc bottle of my Impact contained inadequately dried air. I noticed this during the last fill when I removed the hose from the gun and there were a couple drops of water around the fill nipple. Then when I bled the line of the 100 cui fill tank, the air was misty and left a damp spot on my pant leg. Very bad!

I’m asking for recommendations on how to best move forward in terms of removing all moisture from the gun, replacing/repairing o-rings or other parts that may be damaged.

As for the bottle and fill tank, I’m thinking it should be straight forward: degass and remove the valves, clean, dry.

As for the gun, I’m guessing I should take the gun completely apart - or at least until I can access the inside of the plenum, carefully drying everything as I go with lint-free wipes, swabs, maybe a blow drier. And relubing all o-rings that don’t appear to be damaged.

I’ve since corrected the moist air issue with an improved filtering setup, so this wont be happening again. I’m very frustrated with myself for not being more knowledgeable about proper air filtering before I started using the gun.

Thanks for the help guys.

I new before I bought this Ghost that I was probably going to be limited on trigger unless I go deep or send it off. Unless I'm totaly missing something I can't get it even close to my liking with just the 1.3mm hex adjustmants. I have to it right were it won't cock then a we bit back & done. Still heavy as all get out, It gives me fits because I know I can do a sub 1/2"@100 group with this Ghost on any given day with 50.15. , but fighting this trigger has me in a corner. Off to Derrick or I do it myself. It doesn't look easy to get it were I nee it.
This was the 1st 3 of 5 @ 100 & woulda been 1/2" all day. I took pic at 3 as I know 4-5 will be trigger blown.

4 & triiger blew the 5th
I was totaly in the 1/2& under game till I trigger pulled it.
What is everyone doing to get there triggers in a doable mode for bench @100 ?

Need info, does anyone know if the .25 barrel is a poly or a grooved barrel? This is 2022 GCU2 gun.
Thanks
