Ordered some JB bore paste from PA last week and added 4 tins of JSB 18.13's to the order, same shipping cost. Opened a tin of the new pellets yesterday and wow they won't even go in my barrel, excessive force needed to get them through the breech seal. So today tried about 20 of them on the Pellet Gage none will go through the largest hole which is 5.57.
