Hi TT,

My bow is a little lighter, a 46#, but I’m shooting 8.2 grain per inch shafts, Beaman Bowhunter, 400. I’m trimming them to a little over 30″, use a 50 gr insert, 75 gr steel adapter and 225 gr Tuffhead. All assembled they weigh in about 625 and balance at just over 28%. They fly great. I did a paper tune on my field tips, which are the same set up and they punched some nice round holes.

Just a guess, but I bet you could get away with trimming another inch or so off and match your 50#er.

I followed Troy’s advice to the letter when I first set these up. His advice was very valuable to me.

Have fun, dwc
