I drew a mountain goat tag in Montana this year. I'll be archery hunting and was wondering if the TBR mode of the 1600B would work with the ballistics of an arrow? I like the quality and versatility of the 1600B but my primary usage will be bowhunting. That being said, i also do some long range rifle shooting. My understanding is you select a certain ballistic cart within the range finder, but they were rifle ballistics tables. There's a big difference b/w 300 fps and 3000 fps at distances under 100 yards. Does anyone have experience with this model in steep terrain while archery shooting? Thanks
