Thanks Marco.https://www.starlinebrass.com/7mm-08-remington
It is on back order at Starline. That means you can order it and it will generally ship within one week. They pay shipping.
I am probably going to go with Starline. The 7mm-08 will probably be saved as a later project, as I am working loads on other rifles after deer and duck season are done.You can form 308 brass to 7mm-08. Simple one pull on a f/l sizer.
As mentioned, the neck may be thick. And it may end up with a "donut" inside the base of the neck.
Another option to look for, for quality inexpensive brass is PVRI Partizen (PPU).
Good info. No, I am not OCD or a precision shooter. If I get a bang, good velocity and acceptable accuracy, I am good.In resizing 308 Win brass, if all the brass went into neck thickness and none into neck length, going from 0.308" to 0.284" will increase wall thickness by 0.00107", and diameter by twice that. Most 308 Win cases run about 0.014" wall thickness. If you have that, increasing it to 0.01507" and seating a 0.284" bullet still won't exceed the SAAMI maximum for the 7mm-08 cartridge neck. So you may not need to turn anything off. That said, some 308 Win brass can be extra thick to start, so what you actually want to do is to try a few cases and seat a bullet and measure the OD of the neck over the top of the bullet. As long as it does not exceed SAAMI's limit of 0.3150" anywhere, you don't have to do anything about turning necks unless you want to for OCD reasons or to try to increase accuracy.
Ah yes, thanks for reminding me UN. I really have no plans on actually loading these since I have plenty of factory brass in 6.5CM. It was merely an exercise to see if I could do it. I’m going to check on it though out of curiosity just for the learning experience.Going to 6.5 CM is different in that its shorter head-to-shoulder dimension means you wind up moving part of the 308 win brass shoulder up into the neck. If you do that, you need to check to be sure that move hasn't formed an internal donut thick enough to interfere with your seated bullet. If you seat a bullet down into such a thickened place, it can fatten the neck enough to have no clearance in the chamber neck, making normal bullet release impossible and greatly raising pressure. You then need either to ream the donut out or be sure you don't seat your bullets deeply enough to get their bearing surface in contact with the thick place.
Much appreciated. I have 308 brass coming out my ears. I got 100 Starline new brass from Gunbroker as well, so I should be set up. Just need to get the right bullet and make sure i don't mix loads up with my 308.It should be just a simple pass through the sizing die and maybe a trim to length, but that's all. When I first got back into 270 Winchester I had a lot of 30-'06 brass and very little 270. It was one pass through the die and good to go. I've shot hundreds of them without the slightest problem. 308 sized to 7mm is even less of a change. Having proper headstamps is well and good, but it means little or nothing to a wildcatter, and those of us who are avid reloaders shouldn't let it bother us either, especially in times of shortages. Sure would be nice to see better availability and prices on primers.....
