arrow weight and being legal ?

[nw_bowhunter]

To be legal arrows must be at least 6 grains per pound of draw weight with a minimum weight of 300 grains. I'm at 70 pounds draw weight so I would need 420 grains. I was shopping for arrows yesterday and ended up not buying them as I was unsure I would be making the correct weight. My current arrow is 10.3 grains and draw length is 29.5 which should roughly weigh 303.85. I use 100 grain broadhead so I'm assuming my arrow should weight close to 450 (assuming aluminuminsert and blazers vanes equal 50 grains). Several arrows I looked at were around 9 to 9.5 grains per inch. Based on my minimum of 420 these arrows would not be legal or do I just need to be a minimum of 300 grains? I might be over complicating this.

You're correct in trying to get above 420 to be legal.  It's not all that easy with the arrow choices available.  Nocks are around 9-15 grains, inserts 12-20, regular Blazers are 6 grains each.

Always try to get extra weight for hunting.  Heavy arrows go through critters.  Light and fast gets the standard 12" of penetration that you see so often on tv.

You do need 420 at 70#.  You could add brass inserts to your arrows.

The 300grn rule is for people hunting with less than 50lb bows. Beyond that you need 6grns per pound of draw. So yes, 420 minimum for your 70lb bow. There are lots of ways to make weight but if you must use a 100grn head and aluminum insert then a 10+gpi shaft is what you'll need at your length. You can also go to gold tips site and build your own virtual arrow to get a good estimate of different setups.

Ok thanks guys. So I guess I need do the brass inserts or goto heavier broadhead, or stay with the 10+ gpi

Correct. However, if you use a brass insert (100grns I believe) you may need to jump up a spine to .300.

I am tagging this.  I was shooting Carbon Express Crush with Nockturnals and 100gr broad head, which weighed out to 450gr, at 73 lbs on my old bow.  Now I am going the GT Hunter Pro's 7595's with Nockturnals and I might bump it up to a 125gr broad head also and different bow set to 63lbs.  Total weight I need is 378gr if I figured it right.  GT Hunter Pro's7595's weight at 29" is 258.1 gr.  I think I am going to be fine even if I stick with the 100gr broadhead.

A 7595@63# may be a little stiff for you. Especially with a nocturnal and 100grn head.

What do you think?  I am still learning.

Well russ, my opinion may be a little convoluded due to my never ending quest for extreme FOC. I also shoot and recomend a heavy arrow especially for those who hunt elk with bows under 70lbs. That being said, a 340 spine arrow (7595) will work just fine from your bow but you might consider ditching the nocturnal and switching to a 125 head. While weight in the front will decrease spine weight in back will increase spine. You could probably even get away with a brass insert with that setup at 63lbs. It all depends on what your trying to achieve,  light and fast or heavy with more momentum. But that's just my either way I suggest playing with the "build your own arrow" tool on gt's site.

Ya i have been debating on going to a 125 gr. head instead of my 100. I shoot 425 @ 70 Pounds. Plenty of KE but arrows are long. I use the CE. might cut them down an little and go to 125s?

[jstone]

also thats out of a 29.5" draw Z7

Its one thing I love about my gold tips. I use their insert weight to get the foc where I want it and make legal weight.
Im shooting prohunters 300spine cut at 30" with a 100gr head, nockternal, and 50gr weight. Which puts me at 470grs, 13 foc and they fly great and penetrate so much I have a hard time not going through targets.

For the record, your standard shaft size should be a .400 but if you can tune a .340 at 63lbs then do it.

All I want to do is put meat in the freezer but I did just join the Cedar River Bowmen club so I going to learn even more.  Thanks for the input.
