So if I shoot a a.)400 gr(total arrow weight) vs b.)600 gr(total arrow weight), same razor sharp broadhead at say, 30 yds, except one bow is shooting this arrow a. at 320fps and b. at 250 fps, which one has more penetration and why?
5 years ago I tested this theory with my recurve against a compound with an over draw. My recurve shoots about 210 fps, his compound was 260 fps. My arrows weighed in at about 600 grains, his on the compound were 400 I think it was. Whatever they were they were much lighter arrows. Both arrows were tipped with a bear razor COC broadhead. For the test we used a 5 gallon pail full of sand. My recurve smoked this compound for penetration at 10 yards. I had 2 holes, the compound only had 1. Thats momentum!!
