BH Weight?

[WapitiTalk1]

Mr. Elknut's thread on what you're gonna shoot this year got me thinking (yep, dangerous I know). I'm not a gear head so I really don't know. What is the difference between a 100 and a 125 grain broad out of the modern day, fast bows? Do the 125s give you more stability, more forgiveness with a not so perfect release, and shoot only a bit lower out to 50 yards? Curious to hear what you smart guys say about this.. I shot the Shuttle T 100s for the past two years and they seem fine but will a 125 head give a guy a bit more stability with only minimal drop in trajectory? Thoughts? Thanks.. RJ

Yessir, the 125 grain head will give you a lil more FOC, and the arrow will fly a lil more better. I know several guys that switched to 125 grain heads over 100 grain heads. Joe Bell from Bow & Arrow has done a lot of shooting with the two heads and he swears by the 125 grain head now...

[WapitiTalk1]

buglmin.. What is an educated guess on drop in trajectory at say..... 50 yards between a 100 and 125 GR BHs? I would imagine the addition FOC may provide a bit more KE if one is shooting decent poundage?

[dotman]

I didn't see any differnces in accuracy but did notice a significant drop between the two, I'll stick with 100's. Yes I could have resighted the bow but the 100's fly so dang well out of my bow no further testing was needed.

[Swede]

To know which will fly better, test both with your bow and arrow setup. It is not as simple as 125gr. is better or worse. Factors like FOC (arrow balance) and arrow spine can change with different weight broadheads. It may not be much, but I have found 100s are better with my setup.

[buglmin]

we are only talking 25 grains here, and you shouldnt notice any drop in arrow trajectory. 25 grains out of a compound shouldnt even give you noticable spine diffeence even. The thing you will notice with a slightly higher foc is more stabile arrow flight, better wind bucking ability. 25 grains wont give you more KE or anything. We are only talking 25 grains here. You'll foc will only move bout 1/2", but just that amount in change will improve arrow flight. To see a change in KE, or loss of trajectory we need to start talking arrow weight change around 100 grains.

Im with Swede, 100gr shoot very well out of my setup.
To increase my total arrow by 40gr [without affecting spine] i add a length of trimmer line inside the shaft.

Total arrow weight is 420gr.

[ElkNut1]

I use a minimum of 125grn for compounds & up to 150grn heads at times. Then there's times I add a brass insert for even more up front total head wt. I've never hunted with a 100grn head. There is more structure to a 125 over a 100, They are more solid feeling in most cases.

At 50yds there is aprox a 2"-3" difference in drop, no big deal as most use pins anyway so a slight adjustment is needed to remedy that. Hit them where they live & they will go down. (grin)

Another variable to consider. Interesting thoughts on BH weight.

[pointysticks]

i shoot a 100 gr head. i like how they are typically smaller. for example, a 125 montec is HUGE! i feel (just my opinion) that with a smaller head, the "Wings" will catch that much less air to steer the arrow.

i do however love higher FOC, so my arrows have 30 gr of added inserts at the tip. inside the arrow screwed to the insert. my setup works for me. i had to step up to a .300" spine arrow to have the higher FOC.

crazy voodoo magic sometimes.

[otcWill]

More FOC=more stability=more forigiving. I like 125's though I am quite efficient with 100's. Small form issues when in the heat of the moment (very common: "I don't know how I missed") will result in a larger miss with 100's. Basically the higher FOC will give you a greater margin for error.

Going from 125 to 100 you lose around 6ftp ke so its not enough to really matter. Speed lose might be 10-15 fps again not huge difference. Out of my setup 100 has always preformed better, i've tried from 75 all the way to 150.

[Indian Summer]

Great... now I gotta go try some 125s. Why did I click on this thread

if your on the edge of your arows spine, 25 grs could make a big difference. it will slow your bow down a small amount reduce ke as well but your momentum will be increased. plus a heavier arrow will reduce some sound in your bow. im a huge fan of heavy arrows with high foc. the thing i see with a 100gr head over a 125 is ther are more options out there for the 100gr. heres some data from my bow hope you dont mind.(last yrs setup) 484gr arrow,100gr head, 305fps, ke 99 and change, momentum .65 something. this yrs setup. 580gr arrow, 150gr head, 274 fps, ke 97.4, momentum .7080. these are big changes in my arrows went from a 350 spine to a 300 spine. i personaly dont see a huge advantage in a 125 over a 100gr head of the same design. just a slightly higher foc and momentum. jmo though

[buglmin]

Now Im confused, enough so that I ran down to the pro shop to shoot some arrows through the chrony, and not once, after 20 minutes of shooting and using 100 grain heads and 125 grain heads did i see a lose of 10-15 fps, and that was at 30 yards, point of impact was less then 1/2". Am I something here?
If you start to get wind plane using a bigger head, its a tuning issue...and if youre on the edge of the spine, then you should see it in arrow flight from one arrow to the next. And Paul seen the difference cause he went to 150 grain heads. most guys wont even notice a change in 25 grains. Heck, Im willing to bet that most guys arrows are off 10-12 grains in arrow weight and they dont notice it...

30yds is a long enough distance that you may not see a spine issue. i talked to the lead bow tech at carters archery aka crackers. he told me he does all of his tuning at 21' and tunes his broad heads at 21yds. he stated that in all of his testing, them two distances worked out the best for every bow hes tuned. now i shoot through paper from 21' when ever i change a head or add weight. you can see right away whats going on with your arrow in flight. fyi nock tear right to heavy of a spine, tear left= soft spine. i dont really make a big deal about the weight of my practice arrows as long as there with in 5grs, my hunting arrows better be with in one grain.

What bow are you shooting with draw weight and length? Sounds like some similar to numbers as mine. I would like to go to a 125 grain head I'm thinking.

[JJ Overkill]

i shoot a bowtech destroyer 350, 70# ,30"dl. when i sent my bow to carters. the guy i talked to said hes never seen a 350 as fast as mine and he didnt know why. with a 350gr (ibo weight) arrow it shot 358fps.

[WapitiTalk1]

Hmm.. Interesting. I switched from finger shooting two years ago to a release and a newer, faster bow (finally put the old Darton Viper down). I settled on Shuttle T 100s as they flew the best of all that I tried but still...... I remember the stability the heavier heads provided with a marginal bad release with fingers.. I may try some of the 125s to see if they fly a bit better for me. Great feedback gentlemen.. Thank you. RJ

For my longbows the Magnus 125 and 140 2 blade broadheads fly true on 2016/2018 arrows. I do not detect any planning.

Darton Viper?? Man oh man...actually talked to a guy the other evening thats still shooting my old Darton Wrangler...Im shoot my Darton 3800 at 64#, 27 1/4" draw, 420 grain carbon shafts at 328 fps...my hunting set up will be shooting at around the mid 280's. Love fast bows that you can control..

Slick Trick 100 gr Standard on the wheelie, and 125 gr VAP Terminators on the Black Widow.

[JJ Overkill]

irony, i responded to this post yesterday and today i was tuning my wifes bow. we tuned with a 100gr head perfect bullet holes, put a 125gr head in and nock tear left. weak spine with a 125. time for a new arrow setup for her.
