Pellet Diameter Resizing Die

After running through 7-8 tins of pellets. I've discovered my barrel really likes pellets that are .257-.259" in diameter. Anything above and below that accuracy falls off the rails. I looked online for a pellet resizing die and the only thing that keeps popping up are gauges to measure pellets. I know I can get Hornady to spin me a resizing die but is there someone in the pellet industry that has already cornered this market?

Just Google pellet sizer. I got mine from here

My JSB 33.95 average about .2495 . in head size. Skirt will be much bigger. Which pellets are you measuring?

The one from https://www.trrobb.com/ is adjustable and highly recommended.

TR Robb resizer

If you're a dead-set DIYer it appears to be a chunk of round bar that's been drilled/reamed with a standard metric taper pin reamer. It leaves the skirt wider than the head. It has a couple of plungers that push the pellet into / back out of the tapered bore.

Head size or?
 
"The issue, for me, is that it flattens the head slightly in getting there."
You are correct, it will very slightly make a small flat spot on the top of the head. However, I have found that if it's used to minorly reduce the head size, and make it rounder, that mark is pretty dang small and insignificant.
If the head size is reduced by a LOT, then yes, there would be a dramatic flat spot on the top of the head.

I do not shoot competitively, but I love to test things, gather data, and learn. What I have found from my testing - and I do have the TRobb sizer - is that resizing larger pellets down does not yield the same results as sorting for and shooting pellets of the same head diameter. I simply don't bother with it anymore, but I do on occasion sort for head size and weight and then use the culled pellets as plinking or tuning pellets. Of course this is for pellets, not for slugs . . .

Of course, for anything to occur in reality, there must be a cause. Here is what I think the cause is, at least at the summary level - variation in ballistic coefficient driven by the different properties of a pellet sized down, either by a sizer or by the barrel. After all, the edge of the head of pellet is very thin, so no matter how it is sized the lead that is displaced simply gets pushed back behind the head. This leads to a different shape than a pellet that does not have much lead displaced. And since the bearing area on the bore is so small, the difference in drag during the shot is not much different - unlike with a slug that has a much longer area to interface with the barrel.

I'll be playing around with this some with testing with my new-to-me LabRadar as time goes on, but it will be a slow process. But either way, my testing to date did not show the same value in resizing as in sorting.

Oddly I have one of these in every caliber but have never needed to use them 😎
I bought 10 tins of Hobbys for my HW45 .22 but they were not like the previous ones and were too large to fit in the breach without damaging the seal, so I bought a resizer, and used it for 1 tin then threw it in the drawer never to be used again. Same with those Hobbys, they are still sitting aroung not being used.

Damaged the seal? Pellets are lead can’t damage steel . Shove em in & shoot em out. If They are the 11gr. I will buy them . for me airguns are supposed to be short range fun. pellets/ slugs are very wind sensitive what may be super today may suck tomorrow. Shooting lead roundballs out of flintlocks 30+ yrs. Has taught me a lot. Most bullet guns are a poor second. And…..at 76 I don’t need the aggravation.😏😁

I couldn’t get them all the way in the breach without a pellet seater, they are that tight. The edge of the skirt would drag across the breach seal when I closed the barrel. If you lived closer I would say come and get them. I’m shooting FTTs in that gun now, they fit nicely.

I’ve had good luck with them ,FX Royale , Diana 48,
