Ok, using the Dynamic Spine Calculator with the bow and arrow set up I currently have, I'm going to have to use a 255 gr. broadhead to get the spine right. Does anybody have a recommendation on a good broadhead that weighs 255 gr.?
sure, snuffer 160 with a 100 gr insert. sharpen it and you'll be dead on.
Zwickey Delta 135gn (2 or 4 blade) & a 125gn adapter.
Between that & the previous 160 Snuffer suggestion, you're covered! :D
Go with a 100 grain insert and a 160 grain head. The extra 5 grains wont hurt anything
My Eclipse four blades weigh in at 254-256 grains with a 100 steel adaptor. I am not a good enough shot to find any difference betwen their impact point and my 250 grain field points.
Tuskers, or just about any combo you want if you do your own inserts.
Your favorite 125 grain glue-on mated with a 125gr steel adapter ( if you're not using woodies)

Well, I got my problem fixed. My current setup is a R/D Hybrid (I know it's actually D/R) at 41# shooting a 29" Carbon Express Heritage 150 with 5" feathers and 100 gr. field points. I was getting a lot of erratic arrow flight, and very inconsistant groups. I used the Dynamic Spine Calculator to determine that I need 250 to 255 grain point on my arrows to get the spine right. While at the local archery shop shooting, I had a conversation with one of the guys behind the counter about adding weight. He said that we could try the new Gold Tip end-load weights. So, we removed the nocks, and using the tool Gold Tip supplied to them, we added 120 gr. of weight to the inside of the arrow at the insert, and put 125 gr. field points on them. All I can say is WOW! It was like I was shooting a completely different bow. My groups were tight, and consistant and the bow was much, much, much quieter with virtually no hand shock. I could not believe the difference it made. I shot for over 2 1/2 hours. Oh, I still shanked a few shots, but the arrows flew like lasers to the target. So, if you're shooting carbons and want to add weight, check on getting you some Gold Tip end weights.
D.A.
well done.
I use the GT weights all the time,you can make smaller adjustments with them to get the tune right.
150 gr Grizzlies with the Ashby grind, 100 grain steel inserts - plus 100 grain brass glue-ins...
