I have two recurves that I bowhunt deer with and one of them is a 37# bow.
Last year, I shot a very heavy 535 grain 2114 aluminum arrow out of it and this year, I'm trying a lighter 2212 aluminum arrow that will weigh somewhere between 471-481 grains after I tweak it a little more. This will give me a heavy 12.72-13.00 GPP arrow.
I plan on bowhunting deer with this lighter arrow setup with my 37# recurve.
