Arrow weight management question

[The Gobble-stopper]

I weighed all my arrows today, using the same 100 grain tip on each of them while weighing. They all weighed in within one tenth of a grain between each other. Except one.. That one weighed in 6 grains heavier. My question is, is that enough to worry about? When it comes to accuracy. Set up weighs 473 grains, odd arrow weighs 479. Also I specifically looked up the weight factor on forums, curious what weight to use for elk. I have a friend that works at in the archery dept at Cabelas. And he shoots almost a 500 grain set up for elk. Yet on the forums some of them say that is way to much weight and you will have to lob the arrows just to get barely 40 yards. My bow speed is at 302 FPS right now. Should that be any problem? Or should it shoot them fine out to 60 without any problem?

[Mudman]

Maybe at longer distance but 1.2% should not change much.  I not expert, but I only notice a few inches at 40 yards when moving up 25 grains on my tips. 60 yards would be much more.

[BULLBLASTER]

My arrows are over a 12 grain weight range and shoot together to 100 yards. 

[Fullabull]

I would leave it as a practice arrow...

[coachcw]

302 fps with a 470 grain  arrow will be wicked ... it should Cary as far out as you wanna shoot. How does  that arrow fly if it groups with the rest shoot it but if it's just one eliminate it or use as a practice arrow . What's the bow set up your shooting ?

[The Gobble-stopper]

Infinite Edge Pro, 68lb , pile driver , havnt pick a broadhead , fixed or otherwise. But have been practicing with the 100 grain head. Crono"d it to 302. Bowtech advertises it to 310, but told me it would actually shoot to 325 with the right set up. Havnt found that set up. But do not figure an arrow over 400 will ever get that fast.?

[Jonathan_S]

If your setup is shooting accurately with a 470 grain arrow at 302 fps...pick a head and go kill something.  I wouldn't change anything...and definitely not in September.

it would seem to me that the small differences in nocks and fletching would make a bigger difference in point of impact compared to 6 grains    My arrows are all between 430 and 440

[The Gobble-stopper]

Sounds good, I just want to do it right. I have rifle and muzzle hunted for years. And have no problem downing the elk. Just want to do it right for the elks sake. I went out last year with a borrowed first generation bow. Just to try it out. Never had so much fun in my life. And it wasn't about getting an elk. Lots of equipment failure but yet still laughed it all off. This year is different. I have a target on one of those thousand cows, and or occasional bull. I actually took 5 of my days last year and exclusively went after a spike by 6 Never got him. He wouldn't leave his 7x7 and 8x8 buddies. This was a born spike by, and not a broken one, so I am hoping he comes back as a spike by 7 this year.

Sorry, but that speed doesn't sound right. With those specs even with a 30" draw with that bow (rated 315 IBO) you should be in the 260's. Unless I'm missing something.
That, or you have the only Infinite edge pro that's faster than a Bowtech RPM 360.

Yea speed sounds off. My bow ibo's 340 I shot a 470grs arrow at 289.9fps. That's at 72lbs and 30.5" draw. That little of weight change should effect much.

I use a friends Chrony F-1. Maybe its off? Probably is according to what you are saying?? Is that a problem going that slow, if it is in the 260 range? And If the bows are advertised as a certain speed. (310 or whatever) Then how do you get it to that top speed. Not that speed kills.

Good read! Now if I wasn't already confused....Sounds like you could get real involved in testing the spines, straightness and weight of a lot of different companys to figure out what works.  Bottom line if my arrows shoot straight enough to make me content... Will my set up kill an elk, provided I choose the right broadhead..

[hogslayer]

The speed is ysually measured at 70lbs with a 350 grain arrow.  So you won't ever get that speed. And your numbers are off.  Did you set the chrono up with the right arrow length before shooting through it?  I am shooting a Hoyt at 78lbs with 32" draw and a 515 grain arrow at 295. It is advertised to shoot 340.

I measured the arrows, they are actually 30 inch from the nock to the insert, set at 68, and 472 grain arrow. My friend said he set up the chrono correct. But doesn't mean the chrono isn't screwed up.. So what speed should I have with that?

[D-Rock425]

What's your draw length?

[D-Rock425]

That bow with that arrow I'd say 270's fps maybe.

[The Gobble-stopper]

What's your draw length?

My draw length is 29

[D-Rock425]

Just did some math you should be down around 252fps.

[The Gobble-stopper]

Is that good enough for elk, everything  considered? I guess I have read so much about bows being fast, and when I heard it was slower than I thought, I was in shock, thinking I have a pile of junk. But sounds like eveyones is slow. I know one thing it is so much faster then the first generation compound I used last year, and faster than my recurve. So anything is a bonus.
 Oh And I have the issue about the chrono figured out. Told my body that everyone says that sounds too fast, he went and shot his bow. The same reading, which is set up different than mine. So he shot his kids 35 lb bow and got the same reading, so it is apparently stuck in that mode. I do not know what kind of a computer or whatever it has, but may be time for him to upgrade. Unless there is a place he can take it. He is in Oregon.

[Jonathan_S]

a 470 grain arrow with a sharp broadhead at 250 FPS is going to kill anything on this continent if you place it properly.

[D-Rock425]

Just remember ibo speeds are not hunting speed.  You could shoot a much lighter arrow if you're in need of speed.  You could drop your arrow weight down to 408 and still be hunt legal.

[The Gobble-stopper]

That is what I wanted to hear.. I guess I just need to practice, practice,  oh and pick a good broadhead. Anyone on hear thinking about going to mechanical for elk..Or is it best to stay away from that.

[D-Rock425]

Stay away.

What will more speed do for me? I assume just flatten out my trajectory.. Any other benefits. I have another aroow I thought about, that weighs in at 435 with tip. Havnt shot it a lot yet, but seems to do all right

[The Gobble-stopper]

Stay away.

What broadhead are you fond of. See if it matches everyone else tells me

[SureThing]

Don't get hung up on speed. Having a very stabil arrow that flies well and groups well is much more important. Remember archery is all about trade offs. Yes a faster set up will have better arrow trajectory and maybe more kinetic energy but you may have to give something up for that. Like noise or a less forgiving bow. At this point in the game you are better off staying with the setup you have and get a good broadhead. I personally like shuttle t-locks in 100 gr. make sure you have 9-13% forward of center weight. In archery it's all about shot placement and knowing your effective range. next year join an archery club near you and shoot so 3-D tournaments and you can worry about joining the dark side. Until then practice up, shoot straight and have fun. Your setup today is ten times better than what you had last year and I'm sure you will be successful.

[SureThing]

I forgot one thing. Once you choose a broadhead make sure you sight your bow in for them. If they fly exactly like your field points your bow and arrows are probably perfectly tuned. Be happy. In not you may need to do a little tuning if they are not flying well. If they are flying well and grouping then sight them in and have fun. At some point in the future you will probably benefit from fine tuning the broadheads to have the same impact point as your field points. Depends on how OCD you are. That's the other thing about archery, you will never be done with tinkering and tuning your bow. Anytime you change any little thing with your setup it generally has an impact on POI.

[Crunchy]

Don't get all caught up with the arrow weight thing.  As long as you are legal with arrow weight you are good to go.  There are benefits to shooting both barely legal and a heavier arrow.  As far as the weight difference is concerned, shoot it with your other arrows and see if the impact point is much different.  If yes, then don't use it when you are out hunting. 

[earlmarne]

My arrows are only going 268 fps. I love em slowed down, I have way less issues broad head tuning.

[The Gobble-stopper]

Thanks everyone for your insight... I feel much better and at ease. I was starting to get all confused and shook up with everything I was reading. And forgetting what the bow was telling me.
