270-7 WSM

Did I read onboard here of a 270 WSM necked up to a 7mm WSM?Or am I mistaken.

If so just overlook me [img]/ubbthreads/images/graemlins/smile.gif[/img].
I thought maybe >the 270 provides a better neck or something.Anyway i did a search and it turned up 1 million things. Thanks Mike

Re: 270-7 WSM

Ol' Mike,

I have that reamer and we have talked about it some on LRH. I have built LR handguns and a rifle with this reamer and both have been performing very well.

The reason for the design was to use be able to use the high quality 270 WSM brass but with the bullet selection of the 7mm family of bullets.

Re: 270-7 WSM

Who makes the 270 WSM brass?
What's envolved in necking it up ,?just size the neck?

Also ,what is "es"stand for in ballistics? I'm new to reloading ,and only have a Lee set-up and load manual and don't remember anything ever mentioned about ES.Thanks Mike

Re: 270-7 WSM

I'm not sure about the procedure for necking the brass up, but ES stands for extreme spread in velocity.

Mike,

Norma makes 270 WSM brass.

I believe Redding makes a tapered expander. You would just lube it with Imperial or other good lubricant and size it from .277 to .284. Fire-form and get to the fun part.
