Can any reenactors or pyro junkies share with me their method of firing their Gr.W.34s? I am having a hard time getting my rounds to cover more than 100 yds with no wind which isn't very good. I have used Little Hugs Juice bottles with film canister inserted in the end, 2-3 tsp (160-240 grains) inserted into the film canister, 2.75" sleeve inside the 81mm mortar barrel, and cat litter or baking soda as filler.
