Or is it? I am going to have a 10.1 gpi arrow at 32 inches which comes to 323 grains. A 300 hundred grain head would bring me up to 623. I can put in 125 grain broad head to arrow adapter would put me up to 748 grains total weight. Is there any advantage to putting in a heavier adapter still to hit 800? Also should a guy put on the carbon arrow collars like they sell on the Tuff head site? Will they keep the arrow from splintering? Anyway I know this is a lot and I really appreciate all your help. Thank you

shaneharleySounds like fun. You don’t mention what weight bow you are planning this arrow around……There are multiple ways to design a arrow. It depends on the distances you normally shoot or what you might expect to shoot.

Example if you are planning on elk you might expect to take shots out to 30 yards+ .If you hunt deer mainly you would expect shorter shots. You have to decide what is going to be best for you and your hunting style

I am going to assume you have not purchased your arrows yet.

A good compromise in total arrow weight is to “strive” for less than 700 grains and more than 650 . ( 650 being approximate the weight required to breech bone). Newly developed carbon arrows are being offered in less weight per inch and are stiffer in spine. Less shaft weight will allow you to concentrate a larger percentage of total arrow weight up front (FOC).When designing a FOC arrows the old rule of thumb of 10 grains per inch can be ignored.

This compromise arrow would be suitable for all game in North America.It will also allow you to shoot if desired in the 3o+ yd range.You will get less drop than with the 800 grain arrow you suggested .I would expect that you would attain 30%+ EFOC. EFOC will also reduce drop at longer yardage ( don’t miss read this I don’t advocate long shots.Every one has a effective range that they are comfortable at and are accurate at. What I am saying is if you are comfortable and proficient at 30 yards this arrow will be better suited than the 800 grain arrow).

I do recommend that you pick the broadhead you wish to shoot and proceed to build you arrow around it. Their are a lot of ways to vary the weight up front beside the broadhead: inserts, adaptors and footing,

Before you buy broadheads experiment with the weight you plan to hang on the front.Field point ,adaptors and inserts can be

purchased in all sizes and weights and the investment is relativity afordable.

You will have to search for carbon arrows that fit your need. Bow weight, draw length .design of bow (cut to center ?) and weight on front.

There was a video posted some where that arrows were shot with out footings and with .It was very revealing I will try to find it and post it here.

I am sure I did not address your questions in full . EXPERIMENT:D:D

I am sure David Petersen would have some suggestions maybe he will chime in 😀

If you keep your shooting yardage down between 700 and 800 might be a great arrow

Shanharleyuntil you can view the video on footings and make your own determination I would recommend that you use them they weigh about 25 grains
