Forming 9.3x66?

Inläggav Rifletuner » 26 maj 2019, 01:11

Just wondering if any of you guys have formed 9.3x66 from any members of the 30-06 family (eg could also be 35 Whelen, 270, etc)? Or would it be a better option to use 9.3x62 cases? Just looking for recommendations since 9.3x66 cases are not too easily available here.

I don´t have my samples here so I can´t give any measures. But as you probably know the x66 is simply a 4mm longer x62. And you will end up with a very short neck if you try to make x66 of any of the shorter ones. As the case get shorter the more you neck it up, the slightly longer 270 Win and 280 Rem wont, probably, provide too much of a gain in length either.

Thanks for your thoughts. Yes, I understand that necking up the smaller neck diameters will cause the resulting case to be shorter after forming. I also agree that a smaller necked case such as the 270 doesn't seem like a good candidate for forming to the 9.3x66.

I thought the 35 Whelen case might be a good candidate for forming to the 9.3x66, but its nominal case length is 63mm. So by the time it gets necked to 9.3, the Whelen case would probably be as short or shorter than a 9.3x62 case.

So maybe the 9.3x62 case would be as good an option to try form to the 9.3x66 as anything, even though its still going to be pretty short?
