OK all of you math and U.S. Gear Wizzards: a Question

[GazzaS]

Hi Guys,

    I have a bunch of Master Barrels .50 cal barrels in 1/48 scale that I'll never use.  And I need 4 .30 cal barrels (in 1/32 scale) that in photographs look identical to the .50 cal barrels.  Mathematically, how far are the two apart?

 

Thanks for your thoughts!

Visually ? To go from 1/48 scale to 1/35-1/32 scale makes quite a difference. Here is a picture demonstrating the size in 1/35 scale.

[1to1scale]

A .30 cal barrel in 1/32 is .009375 internally, a 1/48 .50 internally is .010416.

A .30 cal in 1/35, it’s .008576.

1/32 is pretty close, other than the barrel design, it would be hard to tell.

.50 inches in 1/48 is 0.0104 inches  (0.5/48)

0.0104 inches equates to .333 inches in 1/32 scale (0.0104*32)

Keep in mind that's bore size, not OD. As long as the length is OK, I'd run with it.

A true 30 cal bore in 1/32 would be .009375 inches

Thanks for your help, fellas! 

Alas, I've found a feature on the m1919 .30 cal that doesn't exist on the .50 cal:

The slots at the muzzle end.
