I just got a new Viper S400 and notice like my R10 I had the arrows stick out farther than I like so I was going to cut them down to 19" to get broadhead clearance. anyone else down that yet and how did it shoot?
If a -10.28 gn change (20" to 19") made a 1" POI change at 20 yards then the arrow flight was impacted. It may very well hit that same spot each shot but it should have hit higher vs lower with a weight drop, right?I have shot it several more times and compared it to the 20" ones and I cannot tell any difference. in accuracy Point of impact about an inch low and left on the 20" ones.
That was at 40yds not 20- and the shorter arrows flew higher. weight now on the shorter ones is 435grsIf a -10.28 gn change (20" to 19") made a 1" POI change at 20 yards then the arrow flight was impacted.

Re-read the post CBH. The uncut 20" arrows had the spread group (right group) and the tight ground on the left are the 19".I don't understand why 20" arrows would open up that much more than the 19" arrows? I too have the Viper and considered possibly cutting them down just because, I don't like to see much arrow hanging out past my rail end. I always shoot 125 Grain broad heads for various reasons. Just surprised that 1" cut off made that much difference. If I knew this was a little more refined testing, I'd cut mine down in a heart beat. PLEASE don't think I'm questioning you, just trying to learn as most of us are. Too hot for me to get out and play with mine yet - Maryland, 90+ degs. & 90% humidity!
Don;t know why they would and it could be my shooting- but from the groups I shot the shorter ones definitely did not fly worse. As soon as it cools down I'm going to do some extended bench shooting. I really like shooting this thing- it's a shooter and fun to shoot.WAIT! That's what I said. I wondered why the group on the right, 20" were that much wider group than the 19" group on the left? I apologized before looking back. Anyway, I know what I got out of this so, I'm good.
