need help with getting right broadheads
Im shooting the Martin Bengal (2010), draw lenth is 27 1/2, my draw weight is 70 lbs, arrow spine is 340 and my broadheads are 125 grain muzzy's. When my broadheads are on my arrows they shoot very high and curve to the right...what do I do to fix this?
Broadehead may be little heavy
Hey Chris your broadhead may be be a little heavy for a 340 gr arrow. YOu may want to go down to a 100 gr broadhead. You could also make the arrow a little stiffer and stay with the 125s. That is my thought
selecting the right broadhead
for years I always shot my fieldtips until just before hunting season then had to adjust my sights for my broadheads (of the same weight). But now that I've learned to tune my bow properly my broadheads and field tips hit exactly the same POI.
The walk back method is good for tuning your bow for your field tips. A variation is to shoot 3 arrows at 15 or 20 yds, then move back to 30 or 40 yds and use the same pin. If your longer yardage arrows hit left, you need to move your rest in slightly (if you're right handed). If they hit to the right, move your rest to the left.
And once you have your arrow groups directly under one another then its time adjust your sights. Once your sights are adjusted its time to fine tune your bow to your broadheads. (My advice is if you are a relatively good shot, you should shoot your broadheads at a target with multiple aiming points and shoot only one or two broadhead tipped arrow at each dot. If your BHs hit high, raise your nock point higher or lower your rest (only small increments - 1/32" at a time). Same with the BHs hitting left or right. Move the rest in the opposite direction.
A great guide for tuning is the Easton tuning guide. You can download it and save it for future reference.
Muzzys are a great broadhead and I've used them for years. But the last 2 years I have been using 100 gr Magnus Stingers with excellent success including a 1000 lb bison. And they are accurate enough to allow me to take a bobcat thru the chest at 35 yds (which is a relatively small target). I've also heard good reports on the Slick Trick BHs. These are basically the same design as the Muzzy but the ferrule is shorter due to the more weight as it is all steel. Also the trocar tip of the Muzzy is replaced by the integral tip of the steel ferrule. The blades are inserted through machined slots and held in place by a washer which holds them in place between the ferrule and insert when tightened. These BHs fly great.
I would recommend that unless you need more weight on you arrow because of spine issues, I recommend you go down to 100 gr.
