Response to Either way, it still comes down to the fact...
JSB pellets have gotten smaller in recent years. I measured a few tins of 18.1gr with a Leadhead pellet measuring tool (like in Ted's video) and couldn't find any that were a solid 5.52-5.53mm. And most were barely a 5.50mm. Needless to say, most of my guns that did well with JSBs now are useless with them.
H&N has a good idea by offering different head sizes, but the ones I tried in .177 were all over the place. The tin of 4.53mm were all 4.50-4.51. So that's basically worthless if you were expecting a "fatter" pellet. Good thing the Crosman Premiers in the box are still decent.
To any of you that like JSBs, I would highly recommend buying only the Air Arms branded ones. They seem to be a lot truer to size overall. Whether it be .177 or .22 caliber. I have converted over to the AAs with pretty good results so far.
