Consider wet fletch.

[RaybowTx]

I've seen so much in the years on these forums about tunning arrows.  Its great to see the detail of arrow flight desired.  But, there is not much on arrow flight with wet and layed down fethers.  Most of us do not desire to hunt in the rain.  But we find ourselves in the rain many times while in the stand.  It is perfect weather  sometimes though undesireable.  All dry weather arrow tunning is out of the window when arrows are soaking wet.  ya, I know this first hand and do try to avoid hunting when there is a good chance of a soaking.  With rain comes the inportance of a well made shot as blood trails do fade.  Bare shaft testing is good but still does not replicate a soaking wet arrow. The wet arrows/fletching is not taken into consideration when tunning for good arrow flite.  I, when on stand during a rain try the best that I can to protect my feathers.  And arrow covers are a pain not to mention that the arrows your protecting are not the arrow that your shooting.  And there is no rotating of arrows when on stand when you notice the movement of a deer 30 yards away comming in your direction.  I'm curious of how others deal with the rain.

I have heard of people using baby bottle liners. It falls off at the shot from what I understand...?

My experience here in WA, is that a properly tuned hunting arrow will not be affected by the rain or moisture .

My Mommy taught me to come in out of the rain.  I love gun hunting in the rain, but I lost a deer back in my compounding days due to a washed out blood trail, so when it starts to rain I go home.  FWIW, I was shooting off a rest with plastic vanes.  Evan wet, I got great flight, the problem was thick brush and no line of sight longer than about 75 yards.  When she hit the brush, I lost sight of her.  She didn't go but 100 yards, but I didn't find her for two days.  She was bloated badly.  So, when it rains, I go home, and I really think hard about hunting when rain is forcast.  Bill

Been thinking about this myself the last two days,sitting in the rain watching my fletching get soaked..... Will be watching this thread.... BTW, I tried the fletch dry stuff and it made the arrow squeek so bad on the nock and rest I  quit using it.

FWIW, I have had decent results with No Snow...it is a weatherproofing for whisker biscuit c-c-compound rests.
Think I may throw a bottle liner in the quiver though...

Why not wet your fletching when fine tuning. Should solve the problem.

Put the BB liner on from the nock end. Pull it till the nock sticks out the bottom of the liner. Shoot. No noise. Liner will fall to the ground. Hap

in heavy rain i do not hunt due to possibly losing blood trails . in inclement weather i tend to use a cat quiver . having said that , as i hunt with a back quiver most of the time , i always carry a sandwhich bag [ plastic ] to cover my arrows just in case am caught out .

A light rain I will stay and hunt, a downpour forget it blood trail would be gone in minutes. A combo of a pop up umbrella, low profile fletch, great tune and black magic tire wet on feathers helps.

Ray, Here is how I tune. I bare shaft out to thirty yards to get me close, then I bare shaft with my broadheads on out to 15 yards to fine tune. When my feathers lay down I still get very good flight, I also use a silicone spray on them. Hope this helps.
