Question about weight up front...

[shreffler]

Can you tell the difference between a 180 gr. broadhead with a 20 gr. insert vs. an arrow with a 100 gr. insert and a 100 gr. broadhead?

I wondered if anyone noticed any "planing" with using a lightweight broadhead. I currently use a 100 gr. brass insert, and want to try a 100 gr. Magnus Buzzcut to give me 200 gr. up front - but I'm worried I will notice "planing" and not achieving my desired arrow flight with my weight not in the head.

Any insight is appreciated!

Thanks,

Alex

I have shot a lot of different combinations and never noticed any variation in arrow flight. I think weight is weight.

you'd have to be a superb shot.

I know I couldn't tell any difference.

I have noticed that I get more broken arrows when i use a heavier BH and a light grain insert. like your exapmle of 180 Bh and a 20 grain insert. it seems to me that the 100 grain insert and 100 grain bh is a tougher combo.

if i happen to hit bone ive had the arrow break right behind the insert a few times. .. or a rock in the back yard

Split the difference...150g Magnus & a 50g insert.

There comes a point where adding weight farther and farther back does show up different.

If, for example, I put a 200 gr point on a 50 gr insert and it flies perfectly, and then I substitute 2 50gr weights in tandem behind the insert and reduce the point to 100 gr, there is a definite shift toward stiff.

I think this is a somewhat extreme example, though.

Alex,

From what I've seen (if comparing a broadhead of similar lengths/widths) you may soften your spine with the 180gr tip.

It's very minimal though.

If tuned properly, a 100gr insert and a 100gr magnus will fly great. I've used a 100gr insert with a 125gr stinger with great results.

For example,
I was playing around with two setups at the start of the year, one with a 125gr tip and a 150gr insert and a 200gr tip with a 75gr insert. To get them to shoot bullet holes, the 200gr tip arrow was 1/2" longer (throat of nock to end of insert). With the field points screwed in, they were only 1/4" in difference.

In my opinion, even though the total weight up front is equal, having the weight positioned more forward will soften spine.

Again, minimal though.

I'll bet there is a slight difference, but I'll also bet 99.9% of everyone who shoots a bow could not tell the difference.

Personally, I haven't tried it but a lot of fans of EFOC are now acheiving it by double inserting a shaft that should be on the weak side for their set-up, but claiming that the depth of the inserts act just like a footing and stiffen the shafts, allowing even more weight to by loaded up on the end.

[Bonebuster]

The farther the bulk of the weight is forward, the more effect it will have.

It`s similar to cutting carbon shafts. When you make a carbon shaft shorter, it gets stiffer. Even cutting 1/4" can have drastic effects on spine.

Moving a percentage of the weight back into the shaft will increase the spine.
