Going to a heavier broadhead question?

[Blast-n-cast]

Will going from a 100gr to a 125gr broadhead have any negative effects other than slowing the speed down? Would the 125gr be more effective than 100gr on an Elk?

i think it would cause a slight dip in your shots, so i think you would have to re-set your pin adjustment. IDK about the elk...

Tried it with field pts but haven't with broadheads. With field tips I lost 6 fps when shooting the 125 vs 100 grn. Difference shouldn't be very noticeable until ranges beyond 30-35 yards.

I would assume that I would have to adjust my sight down some (assuming my arrow will drop a little)

You'll need to retune your bow since the heavier broadleaf effectively reduces the spine of the arrow.

If they fly well a 100 will kill elk as dead as a 125 grain broadhead. I suggest that you read the Easton Timing Guide. Good hunting this season.

Thanks for the input. Where do I find the Easton Timing Guide?

You will have to re-tune your bow and be sure your arrows are spined correctly. IMO, a 125 will penetrate better than a 100, all other things equal.

as stated before a 125 will penetrate better than before if you have the correct spine for a heavier broadhead you can offset that by adding some weight to the nock end of your arrow which will strengthen your spine plus give you more weight overall which equals more penatration but if your arrow is not spined correctly it doesnt matter how heavy of a broadhead you shoot you will not get as much penatration

Is there a chart or some other means of calculating the correct spine? I see the ones listed on the back of the boxes of arrows but they seem pretty general and dont seem to take into account different broadheads
