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?

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.

I would leave it as a practice arrow...

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 ?

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.?

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

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..

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?
