Let me start by saying I don't take shots over 20 yards at live game. The vast majority of my shots have been taken at around 15 yards.
I also like the deep penetration very heavy arrows provide. This past season I was shooting a 602 grain 2117 aluminum arrow out of my 42# recurve. This is a 14.33 GPP (grains per pound) arrow and it was moving along at 157 fps. My 37# recurve was shooting a 535 grain 2114 arrow. This is a 14.45 GPP (grains per pound) arrow and it was moving along at 155 fps.
Since the wind outside hasn't been blowing like a gale for the last two days, I decided to see if I could shoot a lighter arrow out of both bows. I got lucky. I found I could shoot the same arrow out of both bows, but with different point weights.
The 42# bow can shoot a 476 grain 2212 arrow. This is a 11.33 GPP (grains per pound) arrow and it's moving along at 174 fps. The 37# bow can shoot a 496 grain 2212 arrow. This is a 13.40 GPP (grains per pound) arrow moving along at 160 fps.
I did have to put a pair of yarn puffs on the bowstring of the 42# bow since the 2212 arrow was loud upon arrow release. With the yarn puffs, almost silent.
I'm going to test the 2212 arrow out, shot out of both bows, on small feral hogs weighing 150 pounds and under.
