JSB 22 cal. Pellet head size

[PlanB]

I've seen several people here mention 5.53 headed jsb's. 
Where can you buy them and how do I know what I have. My cheap digital calipers say the ones I have are less than 5.5?

Airguns of Arizona will sell them to you. You can specify what head size you're after. I don't know of anyone else that supplies different head sizes beside them.

Thanks Craig. I bet you have measured to see the difference in .53 & .52?

The pellets can also be ordered from Bori at Topgun-Airguns. Just ask Bori for the head size you wish to purchase.

Can you see a difference in head sizes? 
I already have a bunch of JSB 18.13 22's from p a because they pack um better for less bent pellets. I think all they have is .52?

What I can notice is the precision on which they shoot. The 5,52 in my rifle shot fine...it's just that when I tried the 5.53, the shots tightend-up with a little more consistency. I shoot 100 shoots at a target to test the pellet/gun consistency. I had a few flyers in the 5.52, while I had none in the 5.53....this trend has continues thru several tins of pellets. 
You may not get them same results as I do due to the fact that I have a custom barrel fitted to my rifle. But I have tried a variety of head diameters from 5.50-5.54.....5.53 shot the best from MY equipment.
The Tins from Pyramid are in the 5.52....though they are not clearly marked and they do not sell them in different head sizes
Can I physically see the difference between the 2...NO, but my rifle can

This must take into account that each individual rifle may be choked a bit differently, never mind the differences in make and model.

For JSB 22 pellets, do all weights come in different head diameters? What about the 18.1?

On AOA website the JSB 22 sampler only offers different head sizes for the 15.89 gr
