@Jamie a little FOC?
Ranch Fairy Special Field Point Test Pack - .310 (5/16) 2 each of 200, 225, 250, 275, and 300 gn field points, and 2 each 15 gn Point Weight Washersethicsarchery.com
that's alot. I've messed with as much as 200grain add on weights, but there is a diminishing return on weight forward. I got what I needed with 100 grain weights and 125 (225 total up front) grain points on 675-700 gr total wood arrows. heavy hitters even when only going 175 ft/sec.
