Tx200, 2 x HW97's , all like JSB Exacts in 4,52, also partial to the JSB Express in 4,52 as well, none of them like the H & N pellet range at all, they feel like putting solid steel in the breech, it's not the weight of the pellets, as they don't mind JSB Heavy in .177 either, but that so called special alloy used in the H & N don't go well in any of mine, well in the springers anyway, they shoot from my PCP but only had a sample pack so c\n't really given them a test in that
