425 Grains

[Coach Jones]

My new Toelke Chinook bareshafts with a 27.5 inch CE Heritage 90 with a 125 grain point.   My bow is 46 @ 28 and I draw 26 so I figure about 41 lbs.  Anyway those arrows will about 423 grains which puts me at 10.3 grains per pound.   Probably stick a 125 grain Magnus Classic on it.   Do you think I will be too light at all?   That bow shoots that bare shaft with silence and speed.

[JRY309]

Your over 10 gpp,and they tune well and they will do just fine.What do you plan on hunting them with?A well tuned shaft will penetrate better then an untuned heavier arrow.

[Coach Jones]

Deer and turkey.

[LBR]

Don't know about turkey, but it will work fine for deer as long as you do your part.  My best friend's daughter has killed a few deer shooting an arrow that's around 400 grains, but only pulling around 25# on a recurve.  She used a 2-blade Ace broadhead.

38@ 26.5" with a 430 grain cedar with a Bear Razorhead did pretty good on a turkey. A little too good, I should have put the bleeder blade on it to keep it in the bird, but we found it less than a hundred yards away.

I'm shooting the same weight arrow for elk at 53lbs, your good to go

[Michael Arnette]

Good to go! I'd be shooting a more efficient broadheads though...any two blade would be perfect.

I have 2 arrows I use with my 41# dorado riser with SF Elite carbon foam limbs. Arrow 1, carbon express predator 2 2040 with a 100 grain magnus black Hornet total weight 350 grains. Arrow 2, 28" gt worrior 600 with a 125 grain magnus stinger with the bleeders, total arrow weight 323.

You are more then fine at 423 grains, I wouldn't be scared to drop 100 grains off if it gave you a flatter trajectory

[TSHOOTER]

For a bowhunting arrow from a traditional bow; I would not go below 450gr regardless of poundage.  I realize a well tuned, light weight,well placed sharp 2 blade will kill anything walking.  I just don't see a need to push the envelope.  For a 3D setup whatever is legal is fine.  For a big game animal I'm shooting for an exit hole every time. A well tuned heavy arrow will out penetrate a well tuned light arrow every time.

[Coach Jones]

I thought about adding some weedeater string into the shaft to up the weight.   I would like to go heavier but this is where she tunes.   To shoot a 150 I end up at 14 grains per pound.   I think there is a point of diminished return going that heavy.

I was also surprised that I had to go that short on that shaft with that light of head to get her bare shaft tuned.    That Chinook seems to want a really stiff arrow.  According to the 3 Rivers calculator I am way over spined.  I wonder if the 3 Rivers Calculator is using the old spined Carbon Express shafts.

[TSHOOTER]

I think your fine on spine.    I would fletch one up and shoot it.  I bet you can put some 5 inch feathers and 150-175 gr heads on be real close.  Understand this 450gr is a personal limit for me.  I think the point of diminished returns will show up with a light arrow way before a heavy arrow.  That is...if the return you want is a clean kill.

[Coach Jones]

If I put a 145 grain point on there they are ever so slightly weak.   I mean barely.   I actually might try cutting that shaft down another quarter inch and see what happens.   I just hated to get to short on the shaft.

[TSHOOTER]

Have you fletched them?  That can stiffen thier reaction considerably.

[Coach Jones]

No I just bareshafted with what I had.   I was actually going to order some new arrows tomorrow.   I know some people actually like to have a slightly weak bare shaft.  I have some fletched that are 29 inches.   With a 125 grain I get them to group well but can't shoot anything heavier than that.  If I do I get extra bow noise and a loss of accuracy.   Sometimes I can see some fishtailing with a 145 and 175 grain head.

[TSHOOTER]

I don't think 29' fletched shaft and 27.5" bare shaft are a fair comparison.  1.5" can change the spine quite a bit.  I would fletch up the short arrow and shoot it with diff point weights before I ordered new arrows. I really think you can add brass inserts or point weight with that 27.5" arrow.  Good luck.

[Gehrke145]

If your bow is shooting good, I wouldn't mess with it.  The 25 to 50 grain change isn't worth it, if you already have a tuned dialed set up for season.  No question heavier is better for penetration, but its all relative.

[2bird]

In all honesty a arrow in the middle of the road is best for penetration. Too light and too heavy don't penetrate well. Also a very heavy arrow will have a huge rainbow trajectory and is a big cause of non lethal hits. About 9 gpp is normally the sweet spot, and remember if we are talking deer, pretty much anything will kill them. From personnel experience  super heavy arrows with crazy FOC arnt really all that great and (for deer) are just a waste of time, and standard arrow with a sharp broad head that is tuned to your bow is going to kill a deer, period. I would worry far more about accuracy and getting the arrow where it needs to go then gear.

[dbd870]

I would not be concerned at all.

[KentuckyTJ]

Fletch them shoot them through paper at several distances and go with the one that makes the smallest holes.

I shoot 435 grain arrow pulling 45 pounds with 145 grain simmons tree shark lite. I get pass thrus on deer and even went right through a black bear in June and stuck in the ground.. You should be good, in my opinion u don't need to be pulling 60# or shooting a 600 grain arrow, a very sharp 2 blade can get the job done as long as you do your part.
