I have a tin of 250 that I tested in my rifle a few weeks ago with about 15 or more different types of pellets. At 23 yards my 10 year old grey labeled 18.1 grain heavy jumbos shoot almost hole for hole. The old labeled can of 10 year old 500 RS was a little larger groupings. Well I ordered a couple of tins of the new red labeled pellets and the cones had a lot uneven finning on them first of all. I never retested groups with the new red labeled pellets till today. I found that the new red labeled pellets shoot about an 1.5” or larger group at 10 yards VS shooting all in the same hole with the old grey label jumbo heavies...Very disappointing. I called pyramidAir, Airgun depot, Airguns of Arizona and of course nobody had the old school grey labeled ammo left in stock. Dose anyone know where I can get some of the old Grey labeled .22 cal JSB heavy jumbos? Here are some comparison pic of the old VS the new. I’m guessing they must have changed alloys? Also the newer ones have more of a rounded Diabolo head VS a football shaped head on the old pellets. I also noticed different shapes inside the cones. I’m guessing the dies, alloys, and quality control changed along with the owner ship of JSB? I’d really like to find some old grey label pellets to purchase if anyone knows of any for sale. I also can trade for other pellets. I have a lot of alloy and PBA style pellets laying around to swap if needed. You definitely can see the inside of the cones have a different style Between the two pellets.
I came across this post doing some research a few minutes ago and figured I’d add it to my post...

According to the above post the ones that shoot good in my rifle are from die #47 in my gun. The other one posted as die #15 looks like my newer pellets that group poor. You can see my newer pellets look pretty ruff as well. I’m guessing some of it was shipping damage?
