This morning's tuning shoot....

Post by sharkbaitffd » Tue Jun 01, 2010 1:06 pm

All,

So I picked up some Easton Gamegetters 2117's in the 400's. Oh...the Bow is a Bear Grizzly 58" 50# @ 28". Had them cut at 28&1/2 inches. The gr. for the shaft is about 342 plus a field point of 145 for a grand total of 487. I draw about 28 give or take a 1/8th. I have my shafts set perpendicular (nock setting...I place the nock under the nock set...does this matter?) and this is what I found today. I repeated this three times at 10 yards with the similar result each time just to make sure...thoughts...I fear I'll have to buy lighter arrows since their is nothing left to cut :shock:

question: how far to center, or past center is the shelf cut on your bow? and what do you have on the riser side plate for a strike pad?
what tip weight are you using on your shafts?

i would say you definately have too much spine on those shafts for that set up. espeacially being cut to 28.5". i dont think you'll get enough flex out of those even with a 200 grain tip.

i'd try a 2016 at 30" with a 125 grain tip at that weight. you may have to go up in tip weight if you are cutting your shafts down too.

I believe it's to the center-line of the bow. The side plate is a 1/16th piece of leather. I called three rivers and they agreed with you kirkll...too much spine...I'm even overdrawing the bow and they barely hit center (still nock right an inch). I'm going to go a step down in weight and start them longer and hopefully cut them back to get a good spine.

you may want to try a 1916 about 29" with a 125 point if you are pulling right at 28". works for me for 50# bows if just cut to center like the grizzly, which is a fine bow by the way.

Ya might want to try this, I use one arrow to test I start off with full length, I have 3 weights that I use. 100 125 and 150 I cut one inch off to get a get end. I start there I shoot all three with each weight and make notes of how the arrow attitude is.
I'll cut 1/2 inch off at a time, till I start to show stiff with 100 grain, then change to see if it will correct with more weight out front, if it does then I go 1/4 shorter and stop there, I cut another shaft leave it bare and tune my bare shaft to hit perfect as I can get it.

I use more 100 and 125 grains heads than any others. some like heavy heads I'm not that way and have never had a problem with blood trails on the ground, when I do what I'm suppose to do.
My arrows might stick out more than other guys arrows(past the riser) but never had a problem with animals caring. Well one did he grumbled so much it killed him. Besides the extra weight helps with KE.

As long as I can get a bare shaft to fly great, Feathers will only enhance the flight of the arrow. plus I don't have to use as much noise making helical on the arrow for keep it flying like darts.

Now this is strictly my own opinion, but with several hundred animals through my freezer. I'll keep doing it my way.

All,

Thanks again for the help. I will be looking into carbon/wood arrows, my father-in-law Gary said it was really hard for him to get aluminum tuned (from a guy who said he shot fiberglass!!). Again I'm grateful for the help! Anyone want some Eastons cut to 28&1/2??? One is bare shaft and ten are fletched...I'd give you the 12th if I could ever find it in the field next to my house!? :shock:

Mark...I'll get that bow going as soon as I get this arrow thing figured out :D

IF I'm using the Stu Miller spine program right, and you have 1/16" past center w/ a 28" draw and fastflight string, I'm seeing a 1916 cut 29" and 100 gr. point. Or a 2016 cut 29.5" with a 125 gr. point.

I'm shooting Easton LEGACY 2018s at 29 1/2", 160 grain points out of a 61# bow at my 27 1/2" draw.
They fly perfectly.
I believe your arrows are just too stiff.

If it's an older Bear Grizzly bow, it wasn't designed to use a fastflight string. Just a hunch, but I think the 2016 arrow is the better choice.
