I am unsure of the case measurements of the 338 Excalibur and was just interested in comparing its extra volume to my 338-416 imp and was shocked to find the same case volume Kirby was talking about for his new 338 Excalibur so that is why I asked the question. Dose anyone know the base, shoulder and length measurements of the 338 Excalibur?
One sight on the internet said you can make 338 Excalibur case from a 338-378 ?? which doesn't sound any bigger than what I've already got, dose anyone now the truth be interesting to know.
It is possible that I have measured my case to the wrong height with ball powder as I just filled the case, hopefuly someone can put some light on all this gray area
