There is very little drop compared to Exacts but the batch that I have can’t handle wind, also the lead is different from my Exacts need about 15 shoots to close the group when changing pellet from Exact to Premium Exact, tested 200 pellets at 55 yards, the groups closed when I sized them that probably indicates that like an Exact there is also differences in the skirts but because there is more lead they are harder and variations have more impact.

The photo show the weight of 100 pellets.

what scales are you using to get the pellet weights.

I use the scale in the link, 0.001g without a closed, levelled and constant temperature is almost impossible to achieve, for this kind of scale and the conditions that we have at home I assume they have an accuracy of 0,003-5 at the most.

That’s why my reference in this type of scales Tanita only have them in 0.002g

The scale was levelled and all the pellets were placed exactly in the centre, I turn a small piece of derlin to guaranty that also calibrate the scale and wait a couple of minutes for it to stabilize and never allow it to turn off.

I tested these last week too, nothing scientific! I shot them! They came out at the same velocity as my 4.51 exacts with as far as I could tell pretty much the same trajectory but they turned off course easier, moving around as soon as the wind picked up before the normal exacts started to move. I found the same in 14" twist barrel and in a 19" twist barrel. That is the twist rate not the barrel length, both were 15" long.
HFT, for people with only 2 buttucks!

I tried these out of my FTP900 a few weeks back with a view to seeing how they performed in the wind. I did back to back testing with normal exacts, AA fields and AA expresses which are my usual pellet.
At just under 50yds with a fairly constant right to left wind of about 3mph the new premium pellets were better than normal exacts and AA Fields but still not as good as the expresses which were still better by taking half the wind of the other pellets I tried at the same time.

There's a site in Germany that do these for €7.80c for 200. A bloke at our club bought 4 boxes and with postage worked out half the price he'd pay here. RIP off Britain again.

Because I don't like to give a false feedback and had the opportunity to weight the pellets in an analytical scale I give them another try, 20 pellets, brand new scale, warm period 16 hours, calibrated before the test, scale Kern ABJ 80-4NM - Readability 0.1 mg – Linearity ± 0.3 mg.

0,5439 0,544
0,5363 0,536
0,5474 0,547

Min 0,5363
Ave 0,546
Max 0,551
Ext Desv. 0,0147

Also verified the pellets with a 10x magnification they had marks in the head like the average pellet the only difference is the skirt because is thicker and they are store apart they look good.
It will be fair for us the clients if JSB start to sell them at the same price of the others and in 500 units for the ones who like them since the deviations is +- 0,015/2= 0,0075 and no +- 0,001 like advertised.
