Need more than a guess on barrel weight

Not sure this is the right forum, but the information will be for a possible next build.
I have two Rice barrels in mind, and Rice Co does not list the weights for these two barrels. To my knowledge he does not have that information. Estimating the difference in lengths and outside dimensions in conjunction with caliber difference I can't come up with an appreciable difference. If anyone can calculate the real weights, it would be nice to know. I also realize that equal weights will not be equal on the shooter if one is longer than the other due to leverage. I am interested in weight difference only. You Physics pros can shine here.
The 48" choice is size B in 50 cal


The 46" choice is a 45 cal

I would emai them and have them weigh the barrels as that is not a secret science and a scale will tell better than trying to figure it out.

If they will not weigh them I personally not buy.

Give Jason a call and explain to him why you need an exact weight. He is a good guy and I would not see why he would not provide it.
If not, take your dollars elsewhere.

Jason will let you know. He's done it for me several times.

The weight of steel is .283 pounds per cubic inch. A 1" x 1" by 12" piece of steel weighs 3.4 pounds. Just do the calculation of the volume of steel added or subtracted from the caliber that IS listed for the weight and you will have your answer.
