What grain of broadhead do you shoot in your crossbow? I cant decide if i want to go with 100's or 125's this year.

The best way to determine that is by the balance of the arrow ;check this out,you will find that by getting it right your accuracy will be at its best, to answer your question you have to calculate the FOC. Lee

This should help.

I dont know much about arrow flight in crossbows but I do know some about arrrow flight in compounds, balance point plays a big factor in it, so does bow poundage,draw length andspline stiffness

back about 15 years ago I was into shooting compound big time and like alot of people I built my own arrows and knew quite a bit about the subject, I cant remember much about it anymore but my setup back then(and now) consisted of 30" 2114's(I forget the overall weight)and with a 55# drawit ended upthat 85gbroadheads gave the best flight and had the best balance, anything heavier and they got way goofy in flight(paper tune), so I use 85g thunderhead's

after I spent all the time and money in that setup I realised I sort of messed up though, I should have went with 2213's instead, they're a little stiffer and would have allowed me to up the poundage a little if I wanted without messing up arrow flight, but with my shoulder I have trouble pulling over 55#'s in alot of hunting situations anyway so my setup worksjust fine

I switched from 100 to 125 grain becauseI'm now shooting aluminum xx75's and I need a heavier Broadhead. When I shot Carbons the 100 grain Slick Tricks were hard to beat. Now I'm shooting 125 grain Wasps.

I'm shooting 100 simply because thats how my vertical bow is setup and I can buy heads to use for both, but reading the above posts makes me think I should do some legwork and figure out what works best.

I use 100's, easy to find and very common.
I use brass inserts to get the extra weight in front of the Gold Tip II, otherwise I would probably use 125's, I like the forward weight.
A GTII with brass and a 100 has more FOC than the standard arrow with a 125..

I use 100 grain MUZZY 4 blade , Gold tip 11's, 4 inch plastic vanes with brass inserts.....I'm happy.

Have always used 100 and they seem to fly great. First muzzys and now the Tekan Twos.

I have Rocket steelhead 100gr. in front of my logs y'all call arrows. Its in there, so don't stick yer finger on my dot as it will become a nub![8D]
