Currently I am shooting a 50 grain brass insert, 100gr steel adapter, + 160gr STOS broadhead or a 125 gr Woodsmen + 125gr steel adapter + the same 50 grain insert. That puts my point weight between 300-310gr. I have a hankering to experiment with some bullheads, and just want to match weights with what I am using. Problem is they are 125 grain screw ins negating the adapter, etc. So basically I have to come up with a way to put a 175 grain insert into my setup. I got some 8/32 machine bolts last night and sure enough they fit, problem is I need more mass. I am going to look at 3-river's setup and see about that. Thanks guys.
