Hi guys, I haVe rescentley bought myself a weihrauch HW 77. It is quite an old rifle but stil in realy good condition.. I noticed the other day when a friend and I were changing the spring that on the left and side of the barrel where it meats the spring housing there are two small ingravings, one of the is of a flat head pellett and the one next to it of a pointed tip pellett. They were put there by weihrauch when the gun was new and I think that this means that they are the best type of pellett to use in the gun but I am unsure . And if I am right and this is what the symbols mean does that
