Things I liked: They were an alternative to when PA was out of 500 tins. But 3 out or 6 tins weren't onsistent they very by a lot!, they even look different from tin to tin. I was doing chrony work on 4 tins one gave me what the 500tins give me consistent 665fps these went from 672fps down to 652fps!
Things I would have changed: Better quality control for these 250tins more consistency as the 500 tins.
What others should know: Beware the 250 tins MAY be VERY inconsistent!! Maybe I just got a bad batch but 4 tins being inconsistent!! Idk about that just I know for now on I'll stick with the 500 tins!
Things I liked: Accuracy in my rifle and performance on pest birds, and a rabbit.
Things I would have changed: Nothing comes to mind.
What others should know: I chronied these in my Gamo Urban. Not really broken in yet. 795fps at about 2500 psi with an extreme spread of 7fps over 5 rounds. Around 22ft lbs. Performance on a rabbit was better than expected at 43 yards. Accurate enough in mine for a well placed head shot. First tried the JSB Heavies. 18.13. They were accurate but not as effective at these modest velocities. They were 743fps at about 2700psi with 8fps ES over 5. I havent grouped either but I believe these are better in my particular Urban. I noticed a few slightly bent skirts. Doesnt seem to make any difference at all. I have been shooting small targets at 40 to 60 yards. Hit small pest birds from 20 to 40 yards with great results. One last thing. If you have a little trouble chambering these in your Urban from the magazine, tilt the bore upward. Not sure why that helps but it does. Mine is a little hard to push the bolt forward unless I do.
Things I liked: Good quality, fast shipping
Things I would have changed: Not always in stock

The JSB Jumbo Express and JSB Jumbo Heavy both show a head size but these do not. Does the head diameter on these very more than the other weights?
5.52mm and no more or less than any other JSB pellet
What is the head size?
