So how many people go to the trouble of washing, weighing and sorting their pellets? If you do, do you think it's worth the trouble? Any insight appreciated.

Crosman Premier heavy pellets that I used in the ld/SS and USFT, I washed, sorted by weight and lubed them with Krytec wax. It made a very noticeable difference. I found pellets from 10.1 gr. to 10.8 gr. I shot the 10.4, 10.5 and 10.6s in matches. The rest I used for hunting or plinking.

I tried it with JSB pellets and washing and waxing made no difference. So now I weigh them to sort them into batches and shoot all the same batch at one match. So I may shoot all 7.9s or all 8.0s and I even use the 7.8s in my FWB300 that I used in the lat match. On the practice range I have switched back and forth between 7.9s and 8.0s, just to see if it made a difference and if there was, it was too small to see. So the sorting by weight may be something that just makes me feel better for whatever reason. I do find the odd 8.1 gr. and 7.7 gr. pellet in the tins and think they may make a difference at long range especially. There are usually a dozen or so in a tin of 500 and I just toss them.

Don, who has won many matches in Port and the Canadian Nationals more than a few times, uses JSB heavies right out of the tin, completely unsorted.

Hi Guys

From what I've heard at the Worlds is almost all the great shooters, don't wash pellets, they weigh them. My good friend Mark Besette (Berty) said that there is a big difference in shooting a 8.44gr pellet and shooting a 8.90gr pellet. He said that in an average can it can go from as low as 7.5gr to over 9gr. That will make flyers come and go like no one's business. I shoot right out of the can. I just bought a jewlers scale for $20 on ebay. Most of the guys at the worlds advised me to get a scale that goes to a thousands of a grain. (0.000)

See you guys

Biagio

Find a good batch and don't bother weighing.
JSB totally irrelevant upon size in fact only ever come across three batches in 15 years that measure whats stated on the tin.

Used to weigh JSB until early 2008 had from 7.2gr to 8.8gr in same tin plus 4 different sizes. Used to get out of one batch 70 pellets from a tin with four sizes! They can be that bad in fact have several sleeves only fit for melting down, cant even get a chrono reading within 70ft/sec.
Even close range 40 yards that equated to 1 miss every 5 shots, out of my hands.

Its not so much the weight issue been there done it and used to use 8.2 to 8.5gr of which group size exceeding 60mm in height. Size the skirts 4.5 as heads well under around 4.46 to 4.48 tops the 4 height group then became 6.3mm hole at 55 yards.
Decent batches as used by Conor in Italy same rifle will not leave a .22 hole straight from the tin.
JSB know when they have a good batch, draw your own conclusions.

Aren't "match" pellets pre-sorted for matching weight?

'Match' pellets not much use for FT.

Interesting, it seems like there is some good batches, and bad. From what I gather is, that most people buy pellets by the case, or by the sleeve. A case is a little much, I buy 1 or 2 sleeves, with matching batch numbers at a time. Weighing your pellets seems like such a big job. It takes forever to weigh one can. I don't think I can weigh pellets, I shoot them from the can, if the skirt is bent I through them out, but the rest is fair game.

It really doesn't take that long. You can do a 500ct tin in about 30 minutes. I've always used 8.44, so I group in 4 piles: 8.3x, 8.4x, 8.5x and over/under (used for initial warmup)

How long does it take you to shoot 500 pellets? Takes me about 3 matches. Not a bad way to spend 30 minutes - while watching TV too!

I DO FIND that sizing pellets is also very worthwhile, especially in Piston rigs. I use an adjustable sizer that can be setup to whatever size your barrel likes, and it's not a push through type, so the skirt is slightly larger than the head. Again, once setup for the correct size, it's about 30 minutes to size a tin.

When I try a new batch I get the scales out and weigh 15 ish from around the tin. If presentable +/- 0.2gr I don't bother with rest of the batch.
What I do have to do is size the skirt to even get a presentable group at 20 yards. If dont size since theres usually 4 different sizes in each tin that equates to a 60mm spread at 55 yards on 4 different heights. Size the skirt 4.5 which wont touch the head at supposedly 4.52, theyre one hole 6mm edge to edge with a riffy barrel uncleaned since early 2008.

Wow. Many of us have been using 4.53, and unsorted and unweighted we can all typically group under 30mm at 50m. Try cleaning your barrel!

Cleaning the barrel is worst thing I can do on every rifle and barrel ever used.
Takes 30 shots just to get a terrible group, after 120 shots its presentable for club comps, gradually getting better for 4 tins.
20000 shots later looking at 6mm edge to edge subject to the sizing and batch being ok.
9 different barrels used on current rifle all same symptoms, CZ, AA400, Anchutz, P70FT, P800, Lothar Walthers and many more.

Sizings irrelevant on most pellet brands I would put money on it your 4.53 measure 4.47 in general with 4 head sizes within same tin. Rarely have I seen batches measure whats stated on the tin in fact only came across three batches in 11 years.

My ld/SS barrel shoots just over .4" at 51 yards when clean and will open up drastically after about 150 shots. Running patches through until they come out clean restores the accuracy. This gun shoots just a tad under 20 fpe, so that may have something to do with it. The USFT with the same serial number is similar, but the effect is not quite as drastic. These guns seem to be the exception, but do illustrate that with air guns, there always seems to be an exception and very few absolutes.

A word of caution when weighing pellets. check your scale by occasionally weighing the same pellet 3 or 4 times. My scale will give .1 to .3 gr difference on the same pellet.
