I picked up a tin of these JSB pellets at the NC airgun show, along with a used Marauder. The rifle is still being tuned and upgraded by my friend Paul Bracaglia, and I sent some of the pellets to him for setup and testing.
Reading online here, it seems that these pellets are shooting well for many users, so I am pleased with my (lucky) choice. There was no head size specification on the tin, based on the JSB website, these are nominally 6.35 mm, the only size offered.
Today I decided to use a Pelletgage to check head sizes. Thought I would share. I found a tight distribution with mostly 6.38 and 6.37, see histogram:
There was a very noticeable amount of clear, waxy coating on the pellets after handling and sorting into glass dishes. I have seen this before on JSB pellets, but this was very pronounced.
The mean diameter was 6.378 with a std deviation of 0.0047 mm. This was a very well controlled tin of pellets, in terms of head diameter. Hope they perform well in my Green Mountain barrel.
