6.5WSM neck diameter???

[txsendero]

Can some one who has necked down the .270WSM Winchester brass to 6.5WSM with Berger 140VLD tell me what their loaded round neck diameter is?
I am trying to figure out what to use for the chamber neck diameter on a build.
Thanks.

The FIRST thing I do when planing for any build for myself, especially a Wildcat is to buy at least 100 pieces of brass. If it is going to be a match rifle, I size them up or down as the case may be, then turn the necks on 10 to 15 to find out what it takes get a 100% clean up. Then load some bullets into 3 or 4 of them and then add .003 to that measurement and then order reamer. If it going to be a hunting rifle and I can use Lapua brass, I bypass the neck turning and maybe add .004, depending on whether it is a repeater or single shot.
This has worked for me, I am sure others have their methods.
Never base your reamer neck diameter on what worked for some one else, you do not what brass he used whether he allowed .003 or .008 clearance etc.

I can give you the size of the bushing I am using with redding dies, when I get near my shop. If I have not posted that up for you in a couple hours send me a reminder PM. I am always well intentioned but often forgetful.

Thanks dirtball & eddybo.
Eddybo, which Redding bushing die are you using? (FL or Neck sizer? and is it a 6.5/300WSM die or what?)

.293 bushing in a 270 WSM neck die. It is working well using Win brass.

I would go with the above quote lightbulb

I also use the .293 bushing with redding dies, Norma brass and Berger 140's. they size and load great!

Thanks for all the info. I was also wondering what I should use as a trim length, same as for 270WSM length?
