Hm, ok.....well, here are some real world numbers for you.....This is from my set up, nothing changed except the arrow. Draw weight and length remained static....
355 grain arrow flying 318 = 79.7 ft pounds
490 grain arrow flying 282 = 84.8 ft pounds
That's over 5 pounds, which is a significant increease.
Here's some numbers from my Guardian Same Draw weight and length. Same grain scale and Chrono.
326 grain arrow 280 fps 56.77# KE
497 grain arrow 232 fps 59.41# KE
171 grain heavier arrow lost 48fps and gained 2.64# KE If I use the heavy arrow Iwillbe pretty sure my shoots are gonna be close range.
