How does one neck down a .308 case? I am relatively new to reloading. I have a single stage press with FL sizing dies for 7mm-08. 7mm-08 brass is difficult to find, especially now at stores like Bass Pro and other big box stores. But most have .308.

Several post back I provided a link to a recent forum discussion on the subject. You just run the .308 Winchester brass through the 7mm-08 full length sizing die. Set the die up as you normally would. The cases will come out slightly shorter than the 7mm-08 specification but in my case that was never a problem. I never had a need to neck ream either when finished. Make sure you lube the cases and I also lubed the case necks IDs. I happen to have used new factory Remington brass when I did it.

I am not into case forming yet but you have what you need already. You run the 308 brass through your 7mm-08 sizing die. You may need to anneal first, and if the necks end up being thick then you either ream them out from the inside or turn them down from the outside.
You might need more lube on the inside of the case in the area that will be formed compared to regular brass resizing.
At least that is what I gather from my manual of cartridge conversions for this particular conversion.

place an add in the classifieds of this forum for 7mm08 brass "wanted to buy" WTB. 7mm08 is more plentiful than you may think. around here (LA) I never have purchased any 7mm08brass or ammo to get brass. when I first started reloading for 7mm08 I formed about 50-- 308s but never used them cuz I was able to find adequate supply of once fired 7mm08 at local public ranges on the ground!!
you can also trade with guys on this forum, when scrounging save all the brass, sort it then you have trading material . will save you money and help fellow reloaders out. if you find 6.8, or other fad calibers it is more valuable and much sought after and really good trading material. I have traded for calibers I needed and also bought and sold brass.
never had a problem with forum members!

How to :
Lube .308 brass well.
FL size in 7mm-08 die.
Trim to length.
Voila.
The ones that don't split after the first firing will likely last as long as an purpose made 7mm-08 brass.
The ones that do ? Nothing is perfect. Into the recycle bin you go..... You at least got one shot out of it.
If you were very well equipped, I assume you could soften and anneal and all that good jazz, buts it not really necessary for a .62 mm on average reduction.
Your brass will have stout shoulders

I don't know what part of the country you are in but around here in Kansas city. we have some local "craigslist" type websites for guns only. I have access to about anything you want within reason. if you want to pm I can give you a couple sites to check. but finding oncefired 7mm-08 brass is no problem around here usually. I think I have like 20 rounds i accidentally picked up from the range. but if you just post an ad for once fired and leave it up every few weeks someone will contact you with some.. I did that for 243 and I now have a lifetime supply.. I actually stopped taking it and started giving it to my bro for making 260. I understand 243 is much more readily available.. but the concept still applies

If you want me to I can check the local range, I usually find once fired brass there, it is mixed head stamp but really cheap. I use it all the time in most of my rifles.
I actually prefer to use .308 brass to make 7 mm 08. If you do it that way, you might get a thicker neck, which means that it will fit better in the typical oversized hunting throat, and you will have higher accuracy. That's the whole reason that benchrest shooters arrange for only .001 clearance. Tested by seeing if you can chamber the round with your fingers and if it goes, you're fine. I do it this way on purpose.

Thanks for the offer. I shoot my 7mm-08 so little (target practice and hunting only) that I tend to use new brass in it only. This will be my second set of brass for this rifle and the first one lasted me about 5 years (about 4 loadings each before the primer pockets got loose on some).
I totally understand. I can't believe that cartridge hasn't gotten to be even more popular than it has. such a great round! I would encourage you to pick up whatever you can and even if you don't use it for a long time you'll have 500 range brass as a back up in case prices keep going through the roof. in 5 years we're all going to have to be part of the ruling class just to afford this stuff!
