Barrels effected by temperature?

Re: Barrels effected by temperature?

I have done something very usefull today.

I measured one of my old barrels this morning at basement room temperature, poss arround 1 -2 deg, it is brass and measured 6.08 with a digi caliper.

I then put it out side the basement door in two inches of snow buried for three or so hours then measured it again....

Low and behold....6.05mm

So that will do for me.

Just to conclude.

Laid the same brass barrel on the radiator in the dining room for an hour or so 6.10mm

That will be proof enough for me.

i agree,

and if you still think the bore of the barrel will get bigger during cooling..well, your just wrong

Midas youve just proved what we told these scientist's a few posts up, they went all on about aeroplanes and shit but all it took was a simple test like you did and prove what we all knew. Settled lol. Fet came today thankyou also, will post results soon.

This post should have been concluded about 19 posts ago.

When metal gets hot it "expands" and when it get cold it "contracts" SIMPLE

The only issue i have experianced in the cold is issues with my hop rubber causing jams because it had got colder, harder and slightly tighter due to the temperature. Not my barrle size changing by 10mm + or - and not it warping either. (I can only imagin this to happen if the barrle was really hot 100+ deg and then subjected to - temps)

I cant believe people struggle with this.

Obviously it helps people who do. That and there was some pretty persuasive maths given. I started to doubt myself....Obviously I didn't need to.
