Heavy Dangerous Game Arrows....

[O.L. Adcock]

Twang, The ABS Griz Sticks are going to come in 2 weights, 11 grains/in and 15 grains/in. Ed at Alaska Bowhunting Supply is trying his best to get them out there. The down side is going to be the cost as these are American made. The cost should more than work itself out as these dudes are tough!....O.L.

Found some different wire...larger diameter, and about the biggest most perfect size your gonna find to fit into the Nitros.  I now have a 945 grain arrow....just got to see if it will fly out of this 75#@28 ASC.....the quest continues....

[Terry Green]

It flies!!!

And its got the speed still at 12.6 grains per # for a Buff Momentum requirement.  Got some fine tuning to do, and a string change. I'f all goes well, I'll have a 945 grain arrow moving 162 to 165 FPS.

If I move to a 190 grain head, I'll have a 975 grainer moving 160 I hope.  Thats the destination of the quest.....

Tarzan,

Looks like you are about there if you go by Dr. Ashby's .65+ momentum.  Good job.    :D

I'm at 162FPS now due to a string change, and minor adjustments.

I have a 75#@28 with a MO of .68!!!!!!

[Rick McGowan]

Terry sounds good.    Rick

[Charlie Lamb]

Wow T !! Sounds like you got it and the string change helped. Hope to have one of my own soon.

Charlie, the arrows shafts are on the way today.  let me know how they do.  The shafts weighed 543,574,and 640 depending on inserts.  They are 30 1/2in long and I tried to shoot them @ 30in. of a heavy longbow and I thing they should work for you.  See ya, Mark

[kyle]

WOW Terry.  Sounds like you've got the "stuff" now.  Lord help anything that gets in the way of that stick after you let it loose!!!

Kyle

[Terry Green]

Yep, I am most happy.  I think I can get 3 more FPS from this set up....once final tuning is done I hope. Haven't had time to fool with it since these changes were made.

May not sound like much...but with a 945 grain arrow, its a lot, and ever bit will help in the buff department.

[bayoulongbowman]

Mark , I may want to try a set up like that , I think I know a shop that sell muzzy ,great info..#78 Mark

[Charlie Lamb]

Mark...Got the shafts and finished preliminary bareshafting. Everything looks super. I favored the shaft with the fifty grain insert for my first tests. I'll try one with an even heavier insert and see how it works. Got it shooting out of a 78# recurve right now, but am going to back down in bow weight by four pounds. I'll get it through the chrono soon and work up some momentum numbers. After that I'll put the shafts through some "toughness" testing to see what they've got... I suspect they are bomb proof!!

[mark land]

Great!  Glad to hear it Charlie, just let me know how they do.  Mark

Hey!

Just caught this thread, and I have a question; What is the momentum (MO) factor, how does it work, and how do I caluculate it? I got that Dr. Ashby said something about .65+ for buff(?), but I'm lost beyond that.

Any references I can look up?

Thanks

[Terry Green]

David,

Check out the thread just below this one.  I topped it up for ya.

If ya need a really heavy arrow I have one for ya.  2213 XX75 + 29 1/2 inches long,+ with 125 grain head = over 1600 grains.  Oh I forgot to mention that the 2213 is sleeved over a fiberglass fishing arrow!    .....It's for gator hunting.

Thanx, Tarzz!

Rob, D'ya think it would work for griz?          

[Rob S]

Ive seen 500 gr arrows work on Griz's.....the guy was shooting a bow with training wheels    
Otherwise heck ya they'd work!
