Thread: 303 Query

In recent post on same subject there is great photo of two .303brit fired cases. It shows how vastly different chambers can be.this was wartime construction and as long as a std sized factory round chambered n fired it was near enough. Some chambers vastly larger than others.thus you keep cases for your rifle,for your rifle and if get others that have been fired elsewhere,check them in chamber before you start,check again after resizing,if they still won't fit.....ask someone cleverer than me how you can get them smaller lol.
