Brass resizing question

[lovemylegacy]

I have a bunch of 308 brass, can it be sized down to 7mm or 284?

[Mike D]

You mean to make 7mm-08?

[lovemylegacy]

Yes that is what I was referring to.

[LWD]

Yes, it can. But if it's been shot and resized a few times as .308 you'll want to anneal it first.

Most of my 7-08 brass started life as .308 brass.

Once fired brass.

How do I go about resizing brass?

.308 to .284 is one step, just lube it good and run it into the 7-08 die. Check length and neck thickness and trim as necessary.

Thanx Recently I have been inquiring about reloading and will learn about length and neck thickness + all the ins and outs of reloading. Thanx once again, Calvin

Be careful with "lubing it good" as too much lube can result in dents on the case shoulder. However, once you fire it in the new caliber, the dents will smooth out. As far as a lubricant--get some of the sizing die wax from Sinclair's or Midway--best lubricant around IMO.

I agree. It won't take any more than normal lube. I've accidentally resized 30.06 to .270 a few times. It will just have a little more resistance but it will go right down.

You defiantly need to check the wall neck thickness also. It may need to be turned.
