hi klarkon verry interesting i have 2 cassings lenght is 137 R in my
book it is marked 37x137 R 1 pounder us navy . another is mentioned
37x 119 R WINCHESTER ? your picture show the 119 R casing . do you
think that my head can add to my casings ?

[klarkon]

Your projectile was intended ONLY for 37 x 120R casings.

A shorter projectiles were used for 37 x 137R cassings.

[RED LION]

yes you are right this round must have the winchester casing . here are my bulets
from my casings .

So why do you ask when you know it ?..................................and you have the proper projectiles..

[RED LION]

Klarkon i saw it not before you have explain
It. Now after your answer i saw it 😉

[RED LION]

The proper bulets are on casing since i have it 🙄
I would put the winchester bulet on my casing but you said that is not corect so i saw it that i must look for a 37x120R casing
