A few years ago, my buddy and I were out in Iowa turkey hunting and scouting for deer. We stopped by Roger Rothhaar's place for dinner and some shooting. In the process of our little shooting session, Roger found, buried in the grass for a few years a 2216 with a big ol' 160g Snuffer on it. The feathers were gone. He said, "Watch this".
He proceeded to shoot that bare shafted Snuffer tipped arrow about 45 yards right into the heart of his deer target.
I think if you are tuned properly, you don't need any fletching to shoot a big Snuffer!
