Sorting parameters

[Keyman62421]

Now that i have 1 tin shot from my new shipment. Some good.results some so so w/flyers.
Now to sit down and sort . Thru the first tin. All pellets are 6.36 , 6.37
weight 33.2, 34.6. Mark2. I can accept the head sizes but i intend to accept 33,5, 34.5. Everything in 1g.
any experienced hands . Do i need to get tighter. As i mentioned earlier post, the pellets are shiny and seem to have a "wax' coat. I dont know wash or not! Does washing affect accuracy? I know ir helps keep barrel clean. I cleaned barrel after 1/2 tin, dirty but NO lead chunks in barrel.
Do I have my sorting out of order? I need a good skirt inspection system.
Any help is appreciated.

Keyman, I could only HOPE to find tins with head sizes that comparable as long as they are what is marked on the tin!! At least for me head size is more important than grain weight as I shoot field target and a max distance of 55 yards with .177 cal. Both of my rifles prefer 4.52/4.53 head size and I have a very hard time finding tin's containing whats marked on the sticker!! My advice to you would be to head size them first into groups and then sort them to groups as finely as your scale will let you, then shoot some groups with the heaviest and the lightest to see if you can tell if there is an impact point change, then do the same with the head sizes to see if one or the other shoots better from your particular rifle. I too have found that the newest tins I have checked have had a waxy coating on them so I have stopped lubing as I had in the past!! Good luck with your venture in the BORING world if pellet sorting!! J.L.

Here is my experience with weight differences with the JSB 25 caliber mark 2 pellets.
I also have a pellet gauge to check head size. The tins of JSB did show remarkably good consistency on head size.
Skirt size had more variation.

I have found that as long as I size by weight then by diameter I get consistant results with all the ammo sorted, provided that I size them for the correct diameter I use the TR Robb pellet sizer. After weighing and sizing I may have to adjust the reticle slightly for each batch. I like the Robb sizer as it allows adjustable diameter of pellets. The only problem it can only make pellets smaller. The ones that can’t be properly sized go into my plinking box . 
The way the sizer works the hole you but the pellet it is tapered, you just set the depth needed for size then push pellet in using the brass rod,then pull back on the spring loaded lever to eject.

Okay the follow up on the Sorting I've got about a 20% 6.36 head size the rest are 6.37 this of course is only 25 caliber impact frame. You'll notice the left upper quadrant is my sighter quadrant and the first six shots 636 I moved to the right upper quadrant six shots 637. I usually find that my first 10 shots or so are getting used to shooting again shots. I get serious after that at least as serious as I can get. You'll notice the left lower quadrant is six shots or so 636 and the right lower quadrant is 637 about eight nine shots give or take all in the size of a quarter or less. So I'm going with a 6:37 s. These are not washed and I'm not washing them because they're waxed they've not been weighed so I may play around with the weight of the 6:37 to see what that does. I am generally a hundred yard shooter with this gun and out.

this is 50 yds.

Keyman,

If you are a long distance shooter, you want to get the most consistent pellets you can measure, with your means. Get them all the same weight. And headsize. And skirt size. Check out my Field Target Tech Channel on U Tube, I describe all of the above, and more. I do it with .177 caliber, but the procedure is the same, even with larger calibers. Why settle for a 2 inch group at 100+ yds, when you can have groups half that. Any questions, don't hesitate.

Brian,

Your pellet sizer intrigues me. Can you tell me where I might inquire about obtaining one? Any tips for its proper use? Thanks!

Thanks! I placed my order this morning. At the very least, it should clean up the skirts.
