He said that the Imperiator pellets in calibre 30 is 7.62 mm and he sizes his ST barrel accordingly.
FX Airguns and Daystate is making their larger calibre rifles around the same pellet, the JSB Imperiator.
As far as I know Daystate barrels are LW

I have a .30 cal LW barrel sitting here and just slugged it.... It measures 0.308" bore diameter, and 0.300" (ie 7.62mm) across the rifling lands.... If the JSB pellets measure 7.62mm, they will basically fall through, barely touching the rifling.... Does that mean that the Daystate barrels are different than the standard .30 cal LW barrel?.... I have a feeling we're talking semantics here.... While airgun calibers, and pellets, are usually measured by the bore diameter (ie grooves), perhaps these new guns and pellets, for whatever reason, are going by their land diameter.... 4.5mm = 0.177".... 5.5mm = 0.217".... 6.35mm = 0.250".... but 7.62mm = 0.300".... I honestly don't think this mystery will be solved until someone slugs a Daystate and an FX and gives us the actual bore size (ie groove diameter) which dictates the pellet head size.... or we get to measure some of the new JSB pellets....Bob
Price tag is actually 2700
Push a pellet into the bore an inch or so, and then using a soft rod, push it back out the breech and measure it.... It should be a simple matter to measure the diameter across the rifling marks, provided there are an even number of lands.... Likewise, if the bore groove diameter is smaller than the head of the pellet it should be scraped away.... If there are no marks on the head between the rifling marks the pellet head is smaller than the groove diameter....
