need help fast.....(arrow weight question)

[orrbull48]

bought some new arrows for my elk hunt coming up and they sent me the wrong shaft size. the ones they sent me are axis nano's 340's @ 9.5 grains per inch, and the ones i wanted were like 10.3 or 10.5 or something. so my question is should i keep the ones they sent or get the others? i just want my arrows to be heavy enough for elk. i think its 455.5 compared to 487+/- on the two arrows. setup is a 29" mathews dren 72lbs.....hope someone can help....
thanks!!!!!!

I'll be throwin' 9.8 gpi arrows at elk this year. I'm shooting a Switchback at 27", and I don't think mine will even total 400 grains. I think you will be fine, as long as the spine is right.

I am guessing you got 400 FMJ's I would trade them out....your spine wont work...You have to have the 340's

[DrenalinJunkie]

Like Chance said as long as the spine is right, you should be ok.

[orrbull48]

i should have been more specific.....they are the easton axis nano's 340's.....thanks so far!!!

[rrebel83]

Well then they should work great....I would just make sure your pin gaps dont change much...30grains can make a difference.

thanks!

I think you'll be fine, but if you want more weight, add some weight tubes from Three Rivers archery.

Don't worry your arrows are heavy enough. It's shot placement with a SHARP broadhead first and foremost that's most important. Good luck on your hunt!

If that was my setup....I'd be shooting the 300's

[orrbull48]

should i shoot 125's or 100's on those 340's?
