Title: Arrow and broadhead weight
Post by: hoyt77 on October 26, 2012, 07:55:42 PM: Its been a couple years since I've done any archery. I working on getting back into it for a white tail hunt next Oct in PA at my families cabin. I have hunted WA with no luck but have learn a lot and met many goof people to help me. Anyway I'm trying to remember what I learn years ago about arrows and broadhead weights. Can I get some help relearning this info? I need to purchase some new arrows and broadheads not only for hunting WA but also for my PA trip next year.

Post by: Button Nubbs on October 27, 2012, 08:14:04 AM: Total arrow weight needs to be 420gr @ 70lbs. Not just the shaft, its including the broadhead.

Post by: Button Nubbs on October 28, 2012, 12:41:13 PM: Yes, 450 grain total arrow weight. Not broadhead :chuckle:

Post by: Kc_Kracker on October 28, 2012, 01:44:08 PM: ok i was thinking what the... my arrows have no weight stamped on them, how do i find out?

Post by: Button Nubbs on October 28, 2012, 02:31:23 PM: You have to weigh them on a grain scale.

Post by: Instinct on October 28, 2012, 07:36:13 PM: Also the side of ur shafts will have numbers and a gpi (grain per inch). Meaning for every inch that arrow shaft it weighs that much. Ex 8.6gpi.. so you can roughly figure out if you have a heavy arrow shaft to meet the requirements.

Post by: Kc_Kracker on October 28, 2012, 09:04:48 PM: mine are 31" and all it says is 50-75#... nothing else , oh well thats what i get for being broke that week and buying at wally world :chuckle: oh well i planned them being for practice anyways.

Post by: Button Nubbs on October 28, 2012, 09:53:26 PM: I am pretty certain you are severely underspined with 50/75's at 31" and 75lbs. I'd be willing to bet your actually pretty close to flirting with disaster. You arrows must weigh at least 375 to be safe, any less and its almost like dry firing your bow. Ever see those pics of guys with arrows stuck through their hand? Don't be that guy.

I agree with B. Nubbs. I have been trying to ignore these threads, but Oh My! It's time to get this nipped in the bud. KC - I'm sending you a PM with my cell number. Give me a call and we can get you on the right track in just a few minutes over the phone.

Hoyt77 - try and give us as much information about your bow and your arrow as you can. I can not give you any educated advise unless we have all the details like draw weight, draw length, arrow length, spine, brand and model, size and brand of fletching, etc, etc, etc... The more input the more accuracy of responses can be.

Perfect :tup: Some variables with arrow length, inserts and fletching. But all should fall into the optimal catagory with that set-up. Well done.

Post by: Archer45 on November 01, 2012, 07:01:46 PM: Spline is the strength of your arrow!! It has to do with the density and thickness of the arrows sidewalls!. At a 31" draw you should be shooting 75# -95# or a 300 spline carbon arrow.
Also to the main post! At a 29" draw you should used a 340 spline or a 300 spline. Either will work just fine but if you want less arrow bend go with the 300. Also with a 70# draw I would recomend at least a 100gr broadhead. My draw is 30in and I use easton epic 300 and 125gr muzzy three blade broadheads and they shoot just like my field tips(Practice tips). Everything is up to your own preference but spline is crutial! Good luck, practice a lot and have fun!
