I never had tried the HTM blunt. Could certainly see them working on those spruce grouse. Those birds would be a blast! A fellow had a video on here a long time ago walking and shooting several of those. Not sure what he used. I’ve seen many pictures of dead grouse and trad bows over the years, too. Can make a beautiful picture if done right.On another note I’ve been using those Forge converta blunts lately from 3R. Take them and a 5/16 field point to get to your weight and screw it on. Man they work great out stumping. Won’t bury or get stuck nearly as easy. Think they’d do a great on small game too.
