Barrel Wet From Rain

The forecast is for rain on the first day of my Montana deer hunt. Does a barrel wet from water throw a bullet significantly off-target? I shot a Coues deer at 666 yards in the rain a few years ago. We were moving around in pickup trucks, though, and I can't remember whether my barrel was wet. Certainly I would expect a barrel wet from cleaning and before firing fouling shots to print to a different spot but I never tested one wet from water.

And, on a cold day, if you use a barrel condom or a balloon to keep the inside dry...will you end up with condensation making the inside wet anyway?

Inquiring minds want to know!!!

Re: Barrel Wet From Rain

I kind of grew up in Oregon where rain was normal. I have hunted packing a rifle that had a plastic bag wrapped around the scope and action area. Held in place by a small piece of duct tape so it could be pulled off in seconds.

I always walked with the barrel down. I guess that if your barrel was straight up and a rain guage collected one inch of rain your barrel if you had a bullet in it might collect some water

Re: Barrel Wet From Rain

Len,

I would say that a small amount of water would not make a huge difference at common hunting ranges.

That said, if you are stretching things out past 500 yards, I would expect some change in impact.

Most of the serious hunters in my area of Montana will put a small piece of electrical tape over the bore to keep any moisture out of the bore in the rain.

At the shot, the air trapped in front of the bullet will blow the tape off before the bullet reaches the muzzle.

I have heard this is a common practice in Canada and Alaska as well in wet climates.

Good Luck here in Montana!

Len--just put a piece of tape over the muzzle, or a rubber glove finger--then you wont have to wonder [img]images/icons/wink.gif[/img]

Re: Barrel Wet From Rain

Kirby and JB, thanks.

I have used the tape before but I wonder if I end up with condensation inside?

I agree that it won't matter much before 500 yards but that's just the range where my preferred shot opportunities seem to start. [img]images/icons/cool.gif[/img]

Re: Barrel Wet From Rain

Len (Don't you hate if when I start like that.)

How about not having a round chambered, mag loaded but no round in the chamber.

Get some of those dental cotton plugs (like Sinclair sells for cleaning an action) and thread a piece of Pink Andy or other heavy fishing line through it... make a big knot. Have the line long enough to extend the full length of the barrel. Pre load the chamber with the cotton plug and have the line hanging out the end of the barrel. Tape the barrel as folks suggested to hold the line in place and keep the barrel relatively dry. When you're doing your setup, pull the cotton plug through the barrel to remove it, check the barrel clear (damn cotton), chamber and fire the round. You may be able to use two cotton plugs in that big 7mm Magnum Thingy you shoot.

P. S. If the string breaks or this doesn't work I will state I never suggested it!

Re: Barrel Wet From Rain

I doubt if you are going to get cold enough temps for condensation inside the bore to be significant. Taping is essential if you are crawling around in snow or muck.

I like to make an X on the muzzle, then one ring around those pieces to keep them on good. Then spin about six or eight revolutions of tape at the midpoint of your barrel so you have some spare tape to replace if you fire a shot.

Your biggest concern should be the effect of each water droplet hitting the bullet on differing axis - understand that needs a lot of research and was going to ask Dave King if he would help me do a study - maybe we could get some serious grant money and do the work this winter in Florida or on a tropical island somewhere [img]images/icons/wink.gif[/img]

Worries the hell out of me, does the nose tip downward if a water droplet hits the top tip of the bullet, how many droplets would it take hitting one particular spot on the bullet to start it leaning to that side, would water droplets hitting the rear of a bullet have a different effect on flat-base bullets compared to boat-tails. We need answers here... Big problem with the tests might be repeatability - could get expensive if we have to while away the sunny days fishing etc. Might need some help here if anyone is interested [img]images/icons/grin.gif[/img]
