Older bows-lighter arrows?

[Mitch H]

Got a question concerning the arrow I am currently using for 3-D shoots out of a 1960 Grizzly.

My 3-D arrows weigh in @ 490 grains, and they fly great……even out to 80 yards.

The bad part is that even though I have a bow scale hanging here and a draw length arrow, I never measured the actual draw weight of this bow…..until today.

The bow says it is 48# @ 28", and I figured I was drawing it to 50# @ my 28 3/4" draw length…..

Well, I put several bows on the scale today, and this one is actually pulling 53# @ 28", and 55# @ 28 3/4", for 8.9 grains per lb.

The bow is quiet, and seems to be fine with these arrows, but I sure would hate to harm this old gal.

What do you guys think about using an 8.9gpi arrow out of this setup?

Thanks…….

Your fine with your setup, don't worry.

No worries at all. I have been shooting 8.5 grain per pound out of 99% of my bows even the oldies! Shawn

Well, went to a 3-D on saturday, and when our group came out of the timber there were about 10 guys launching arrows across a field at a wolf target. We could not pass up the opportunity to look silly trying that shot.  

Surprisingly, once we launched 8-10 arrows to get the range, two of us were hitting that wolf 2 out of every 5 arrow volley, and 3 out of five a few times.

Big fun!   :D
