JSB Head sizes

[Ghostmaker]

i ordered some 18.13 in 5.52. I received 5.53's

when I contacted the seller to complain I was told that they can no longer specify head sizes when ordering from JSB. WTH!

anyone know if there is any truth to this?

Not sure how valid that info is? Regardless, pellet makers should discontinue selling tins by head size since there is such a large variety of different sizes in those "head specific" size tins!! I would highly recommend sorting whether by measuring heads, or using something like the pellet gauge. I use sizing dies to size my pellets so I always have the same exact size pellets. Shooting from the tin, even the labeled head size tins will get you as many as 6-8 different sizes.

Sure. When I win the lottery and my kid is old enough to fend for himself maybe I'll have time to sit around and sort pellets. Lol

I can hardly find time to shoot.

I understand time being hard to come by. I have a 6 and 4 year old and a 3rd due in March on top of a busy job and a busy part time job tuning and working on airguns. LOL!!

Just making the point that labeled tins are about as varied in size as the unlabeled tins. It is a joke for the manufacturers to even sell by size as that should mean they are all the same size and that is not the case.

I actually have a pelletgage and did try sorting a tin once. I found it consistent enough to realize I didn't have time to sort pellets. 

Maybe I got lucky.

So I contacted JSB. They replied within 24 hrs and basically said my supplier is full of ----

All a tin of pellets that has a particular head size on it means is that the majority 51% of the pellets in that tin are that size the rest will be +/-.05 %. If that exact head size really matters then pellet sorting is a must. If you got them from AOA or Pyramid Air then they only told you that cause that is what they had in stock.

I looked at both JSB's website, Pyramyd Air's and others and do not see optional head sizes listed for these pellets? 
JSB emailed you directly about them? When I place my next order with Pyramyd do I have to tell them to make sure they are 5.52 or 5.53?

Yes I emailed JSB directly.

Most decent pellets are offered in different headd sizes and most decent retailers will stock a selection of different head sizes. So yes if you would like a certain head size you should probably specify that when you order.

You need to figure that out for yourself. Order a few different sizes and start testing. Every gun is different.

Slug the bore and then you will know for sure. Exact groove diameter tends to work best. In general .250" works in most .25 barrels. I size all my .25 pellets to .250" head and skirt and that size works great in 3 different barrels.

What do you use to slug the bore with?

Either a slightly over sized lead slug which would be the true and proper way. Or, you can use a pellet as long as it fits tightly to the bore. Push the pellet in a few inches then push it back out and measure.

AJ,

Whose dies are you using?

 

[ajshoots]

I use Lee custom sizing dies. http://airgunnation.dev/topic/pellet-resizing/

Hi guys, this topic really interests me, I would like to throw this out there, If you go to (sinclairintl.com) website which is for centerfire reloading products, you will find Wilson & Redding neck sizing bushings & dies that work really well for sizing pellets you can get these bushing's in a wide selection of sizes in .001" increments, you will also find arbor presses for these nk.dies. With a little ingenuity these products work very well for resizing pellets. As a side note, if you do have the old "beeman pell size" hand held sizer these bushing fit in the pell sizer almost perfectly, and will be held with the allen head set screw. The bushings are normally in stock, can buy & have on hand in many differing sizes with out custom ordering.
