Inconsistency in Pellets can be frustrating

[ThomasT]

The JTS right out of the tin shot very close to the sorted and weighed JSB in both my 22 cal and 25 cal RAW. BUT, they could not produce better groups than my sized and sorted JSB at 50 and 100 yards. close but measurably smaller groups from my sorted JSB. The JTS are very clean and when I weighed a tin of the 25 cal 29.32 grain pellets, there were about half of them weighed 29.4 and half weighed 29.3 and one pellet weighed 29.2 so they are much more consistent in size and cleanliness!!! Exceptional in those areas!!! The JTS open up more at distance than JSB.
The JTS 25.39 shot very well in my Taipan Veteran too, but again not as small?tight as groups as sorted and weighed JSB. I would use the JTS out of the tin for most shooting I do except for big competitions.

Hello @XSUltimate

Good information and thanks for sharing. I will do a comparison of the 18gr on all three brands when my order comes in. Like @rsfrid Ross, I have always had good luck shooting with H&N and I hope the JTS shoot as good or better .

Funny that you have good luck with the H&N pellets. As a general rule they do not shoot in any of my rifles. But the 11.42 FTT shoot well in my 20 cal RAW and the 9.57 Baracuda FT shoot well in my .177 HW44 pistol. Go figure!

I found the H&N 30 grain slugs shoot very well (moa or better) at 100 yards from my 25 cal RAW HMx. The 9.57 Baracuda FT are the best of the best in my HW44 as well.

Hello everyone,

I just finished shooting a full tin (250 pieces) of JSB Jumbo 15.89gr pellets and found them to shoot fairly consistent at 10-meter and 25–yards. I opened a new tin (500 pieces), loaded 10 in the magazine and had to push with a good bit of force to load the first pellet into the rifle. Made the shot and the POI was almost 1-inch high left of the Bull. Second pellet also hard to load and the POI was 3/4-inch low right. Shot a third and the POI was 1-inch right. Removed the magazine and pushed out the remaining pellets. What the heck ?

Got my Pellet Sizing Tool and inserted the first pellet. Normally a 5.5'ish pellet will drop about 1/3 the way into the Tool and require very little pressure to push it through. With this first pellet and the next four the pellet only dropped in to the point that the Skirt was flush with the opening. It required quite a bit of pressure to push them through and even the Head of the pellet shows where it contacted the inner wall ( see photo - yellow arrow ). I loaded and shot these 5 re-sized pellets and not one was within ½ inch of the Bull? So now I have 500 pellets that not usable. Note the wording on the Tin’s lid that I circled in yellow ~ Carefully Selected ~ really ???

Any chance the tin is marked with a lot#?

I bought some JTS to try this winter in my RAW 22 based on the recommendation of one of the members here that said they shot better in his RAW than the JSB. We'll see.

That was me Ross.

I posted this on 8/11, and I was fixated on the ‘shallow cavity’ JTS Dead Center .22 cal 25.39 possibly being more accurate than the older JSB .22 25.39 MRDs. I did post eight 5-shot groups at 50 yards in some light wind.

My own personal view so far is that both JSB and JTS 25.39g DO shoot very accurately in my RAW at 50 yards, but at 100 yards JTS did not do as well, per the pics in my above post on 8/11.

The QC of JTS vs. JSB seemed much better in visual comparisons. Caveat - I did not weigh/size/sort.

FWIW - Martin indicated ( back in August) that JSB is now manufacturing the original shallow cavity MRDs and another member validated same to me yesterday. However, JSB has a huge inventory of the older deep cavity MRDs that they want to sell also.

Let us know how your RAW does with the JTS, once you test.

IMO JSB has been garbage for over a year now. I have taken to weight sizing then head sizing every batch I buy and have NEVER found any JSB pellets to be as advertised or labelled on the tins. Now H&N, that's a company getting it right IMO.

Thomas T / Ross

Btw, I shoot the JSB 15.89 in my FX Royale 400 .22, Daystate Revere .22, and HW100 .22 caliber rifles. Very accurate in all three for up to 40/ 50 yards, but I am also finding an excessive amount of damaged pellets in my tins. So, I am going to try H&N, AA, JTS, and Rangemaster (when available), and see how they shoot vs. JSB equivalents.

Hello @IMADMAN

I don't see a "Lot#" but the BarCode is 894421000257 if that helps.

Hello @tommyb

Thanks Tommy for this information. My original Tin (250 pieces 15.89gr) did shoot well in this new rifle. However I shot all of them and do not have any to compare with the 500 piece Tin. Using the side lever loading the original pellets was slick and easy with almost no pressure. However the 500 Tin requires me to use some force to complete the side lever action to load the pellet. I can really feel the pellet going into the breech end of the barrel.

All of the review videos that I have watched show that the 18gr pellets ( various manufactures ) state that this is the best at 25-yards and beyond. As stated above, I have three different brands on order so I will be able to make a good comparison.

Thanks again,
ThomasT

Yes, size inconsistencies are very frustrating if trying to maintain consistent performance. Received 4 tins of .177 4.52 mm AA DFH (JSB) pellets in July, all from the same die lot from May, 2021. Using PelletGage only 55% of pellets on average measured the stated size of 4.52 mm, remainder ranged from 4.54 to 4.51. One tin contained only 47.5% at the stated size.

Maybe it’s just me but when offered choice of pellets packed in either 4.51 mm or 4.52 mm sizes, the manufacturer should sort and pack close to that 0.01 mm tolerance, otherwise what’s the point.

Received additional tins from PA yesterday of the of “4.52 mm” AA DFH. All are from same die lot as those in July. On phone with PA this morning and these are going back, wasn’t looking forward to sorting 5000 pellets.

On the other hand I have 4 tins of AA DF from newer production with 100% of pellets measuring the same size. Maybe as speculated it is just the Covid years that are the issue. If so, doesn’t help that old stock pellets from the Covid years are still in the pipeline.

Kudos to Henry (CS) at PA for expediting the return and for graciously letting me bend his ear for a bit about the pellet sizing.

Exceptional in those areas!!! The JTS open up more at distance than JSB.
The JTS 25.39 shot very well in my Taipan Veteran too, but again not as small?tight as groups as sorted and weighed JSB. I would use the JTS out of the tin for most shooting I do except for big competitions.

“The JTS open up more at distance than the JSBs.”

This is a common finding from many (includimg me) who shoot at 50 and greater. I don’t get it.

They are cleaner, less bent skirts, QC and consistency seems to be better, have shallow cavity vs. older JSB deep cavity, etc.

I know the 18g have a lot of wind drift at 100y, but theoretically it seems the JTS would shoot better.

I suppose that the sorting and sizing of JSB pellets makes them more accurate at distance than unsorted JTS pellets.
