Ross Brass neck extension

[CanadianLanBoy]

Hello all,

I recently got to shoot my Ross Model E factory sporter, and I noticed the brass had expanded quite a bit. I understood that this is normal for .303 Ross chambers, but I noticed the internal neck diameter of the brass had expanded a lot more than I expected.

As you can see from the pictures, the dimension increased ~0.020, which is quite a lot.

It's a shame as even with neck sizing case life probably won't be great.

I was wondering if this is normal for these rifles, or if mine was cut particularly large.

Appreciate any responses,

CanadianLanBoy
