So like the title says I need a little help ordering the right die from redding. I'm having a 7mm08 built and its ready in three weeks. I would like to get a jump on shooting this thing by getting a bushing die from redding but the bushings are 40 bucks and I want to order the right one. I think 4-5 thou would be just right for neck tension. Any thoughts on that would be appreciated as well.
I think I could fiqure this one out at home but sadly I'm 2000km away from my gear at the moment.
Thanks to anyone that can help.
 
Relax, the Redding bushings that I purchase now and again are $12 ea., the one that works best for my .30 BR. is .327" for a neck that can be .330" max. or it will not chamber, and require neck turning. If you order them from Sinclair Int'l., they are a dollar or two more, but they are experts and can help you with your choice.
 
Seat bullets into 5 empty cases and measure the neck on the loaded rounds. Take off .001 or .002 from the average and go with that number.

Steel Bushings are cheap at (like Ben said) - $12
The TiN bushings run around the $40 mark and are well worth it IMO.

EDIT: Just read the 2000km away from home part. You are best to wait to get the right bushing rather than having to order another 1 or bushings if you guess wrong.
 
Just for quick figuring, if the neck of your brass is .015" you calculate as follows:
.015X2=.03
.03.+.284=.314
.314-.002=.312"

Some brass might be thinner or thicker than .015", but I think a .312" bushing will get you started. Regardless of what you start with, you will have to purchase additional bushings if you wish to experiment with neck tension. If your rifle is chambered with a tight neck that requires you to turn your cases, this all goes out the window because a .015" neck is too thick to chamber. In that case rather than ordering a bushing die, you might be better off getting your gunsmith to make you up a resizing die that matches your chamber, allowing .002 for the neck and bumps the shoulder back .002" each time you resize.
 
Thanks Ben I'll try sinclairs today see what they can do.

Boomer, I was thinking the same way you are about the calculation but seem to remember measuring .308 bullets at .305. I dont know if .284 is the same way or not.

I am planning to neck turn as well so I think If I can get bushings at 12 bucks I may as well shotgun order the whole lot.

Btw this guy sells Redding product and reloading stuffs at a very good price http://x-reload.com/xreload_en_index.asp
 
Midsouth shows the bushings at $10.94 ea. and the Titanium ones at $19.20 ea....just for your comparison/info.....Ben
 
So I narrow it down to choosing .306,.307,.308 bushing sizes. I go online to order them guess what just those three in the .284 group on backorder. I must be on the right track.
 
Don't forget that the bullet will open the mouth up to fit when you seat the bullet, whether you plan for it or not......Ben
 
Oh really I thought the bullet just sat on top of the powder. Thats why we are so finicky with the charge weight right, so we get the same coal everytime? :p
