Preventing PVC brittleness in winter

Hey all, well it's winter time, and i can't fire my rifle outdoors, but i still want to shoot it. My house is surrounded by 17 acres of woods, that are owned by us, and i was wondering, to be able to shoot it during the winter, could i just shoot it from inside my house where it's like 70-80 degrees? Shoot it out the window i mean. Would that be okay, because then the PVC would be staying warm?

Thank You

"inside my house where it's like 70-80 degrees?"

Sure, but don't stick it outside your window, espesially your chamber.
Or make a copper/steel cannon so you can use that immense backyard of yours.

Pvc doesn't cool down that quickly.
In fact, shooting every minute or two should keep it fairly warm, even outside.

Edit: is it a pneumatic or combustion? Combustions are generally better for winter use, but you should still be safe shooting from inside.

Umm Fnord, it would probably be both. ANd yea 70-80 degrees, usually it's around 70, but my mom gets cold really easy and turns up the heat a lot. K so just don't stick it outside the window,

Yea I would build a metal one if i wanted too, but I'm happy with my PVC rifle. Maybe someday in the future.

You can also just fuel / pressurize the gun indoors then walk outside to shoot it. Like _Fnord said, PVC doesn't cool down all that fast. Even after a couple minutes outdoors the gun'l still be at the indoor temp.

That's what I do. Works fine. I just feel the propane tank and chamber with my hand, and stop shooting when it feels cool. On a cold day, I usually have time for 3 or 4 shots before I put the gun back inside to warm up again.

Peace,

If you are planning shooting it from inside i wont recommind it if its a combustion.
Though its almost 100% controlled, fire is fire and if something bad happens youre screwed.

Just load and pressurize/fuel inside and shoot outside.

But a pneumatic could be fired from the window yes.

I ussualy shoot my guns downstairs in the basement when the outdoors are unpleasant. It's not as good as outside, but it works, and hey, it's a lot better than having PVC schrapnelize right in your face!

You can make a box out of plywood around the chamber of your cannon and stuff insulation(R-30) in it and that will help keep it warmer. Just keep it in the house at night.

I don't think it's that big of a deal, if you're standing in a doorway, you should be fine

I think we should forget about the whole "fire will keep it warm" thing. This post is posted in the "Pneumatic Cannon Discussion".

Go ahead and just build a metal one. You know you want to. :wink:

By the way: Have you thought about insulating the cannon?

Have your grandma knit a nice woolen clothpiece for your cannon to keep it warm :D
