Arrow weight..

[zeus1gdsm]

In light of my recent sighting issues. I figure I should ask the collective about arrow weight.

I am shooting a 2006-7 Matthews switchback solo cam. Set at 50lbs. With a 30inch draw.

I have standard prefab carbon express stl hunter 200 arrows. With nocturnal and 100grain broadheads.

My buddy came over to shoot and he is shooting 400 grain arrows. On a way more basic browning/walmart type compound. He even has some 500s he shoots....

With all the random flight paths I'm experiencing with these arrows is it possible they aren't heavy enough for the bow?

Should I jump up in arrow weight? I'm down to only 7 arrows so it's time to buy new ones.

Easton has a calculator online that I used and seems to work

Thanks. Super helpful...

Lookalike I should be in the range of 380-420.

Down to 7 arrows? That's 7 deer you can shoot.

Just remember weight and spine are different even tho the values are really similar I had a hard time with that

being that long of a draw you're border line between a .340 and .400 ish spine.  carbon express doesn't make a 200 model arrow I think you've got PSE/Carbon Force STL Hunter arrows.  if that's the case your spine would be .424 I believe.  based on what you said you'd be a .400 or so spined arrow as long as it was tuned well enough and your arrow length is less than 29.5".  otherwise your arrows are too weak and you should bump up to an arrow around a .340" spine.  at 50lbs I'd shoot for a finished arrow weight that's 325 grains or preferably more (6.5 grains/lb of draw weight).  the weight will help you with penetration shooting the lower poundage draw weight.

I shoot the same lbs almost same draw and ran a ton of numbers through a bunch of calculators and thought 400 grain is fine. At 30 and below distances 300 grain doesn't shoot massively flatter, not enough to matter while hunting, I don't think.

Thanks all.

Yes your right. I checked them they are pse.

I ordered some carbon express whitetail 350s. Per their chart I'm right on the line of 350/250 of that particular arrow. Other arrows in their other lines said 350 recommended.

I'm going to stick with my 100g 1-1/16 diameter. Muzzies. Unless I should bump up to 125s?

Interesting thread. I just got measured and have a new DL. Used to shoot 31" arrows, now, 28". With vanes, incerts, and nocks I am just about at 300. New FP's and BH's are 100, putting me at 400 total. 55#DW. I was thinking of going back up to the 125 tips and heads, but 400 total should be good for my set up.

 

The big thing is like already mentioned, making sure the spine is on par, and the arrow will shoot the DW you use. A 5060 arrow from a 70# bow might not be a good idea.
