Ok, so I have been reloading for about a year and a half. My normal routine for my 300 win mag brass is de-cap, full size resize, trim to length, de-burr, tumble, then reload again. I anneal the brass after two firings. Some of my brass has been loaded 5 times. I finally had a case separation when full sizing. I actually check my brass under a magnifier to look for cracked necks and small case separations at the bottom of the brass. I don't see any issues. Primer pockets are not loose at all yet.

My 7mm08 is done pretty well the same way but I anneal after the third firing. No case issues as of yet. Some brass have been reloaded 7 times.

So how many times can a case be loaded?

I think the belted magnums do that more so than the chamberings that headspace off the shoulders instead of a belt.

I'm going to get in the routine of loading twice, anneal, load twice. But some guys anneal after every firing and before sizing.

You might want to try partial resizing. When I went from full-length resizing to partial on my .300 WM, my case life increased from about 4 to about 12.

Guilty...but I'm looking for a lot more accuracy than most.

Partial resize and case life will increase, Got 10+ loads from Remington 7mm-STW with partial size and aneal after 3 or 4 shots. did have to trim a couple times though. On the partial sizing I do as little as necessary and check for good cycling before it ever goes hunting.

I made an assumption that that is what everyone does since many of us have advised to do so, many times. But my failure to bring it up again has made me appear to having not covered all the bases.

.002" bump on the shoulders, even on belted magnums.
