My neighbor gave me a Mosin and a Brit 303 SMLE. He’s a great guy! I want to shoot the 303 in the near future. My serviceability inspection went well. I slugged the Brit 303 SMLE bore with cerrosafe and measured the case, case neck, bullet, etc. with my digital calipers of the internal bore of the barrel.
My numbers are displayed in the attachment. I would like to build a few loads since buying ammunition for this gun is outrageously priced right now.
What do you recommend for a bullet size based on my barrel chamber measurements?
