270wsm brass life

How many loads are you guys getting on 270wsm brass? I have a batch that have been loaded 4 times and I'm wondering if I should discard them and go to a new lot.
 
It's also very important to take into consideration how much your loads are stretching your cases. In addition to the number of firings I also track and consider how may times I've trimmed my brass.

Somewhere along my 50 years of reloading, I picked up a rule of thumb to discard casings after 4 trimmings. I don't know how valid this is or how it was determined...but I adhere to it in addition to other factors that I consider during my case examination process.

I also routinely discard cases with 10 firings.
 
If you setup your die to just bump the shoulder .001-.002 you shouldn't be stretching your cases very much from firing. Cases become longer mostly from resizing.
Also book trim length is just a guideline. Your chamber and neck may be much longer than book max. You can measure it with a caliber specific plug and trim a piece of brass way down. Then chamber the brass and measure the length. Trim .010 shorter than your measurement.
Also I recommend using imperial sizing wax. It's by far the best I've tried.
 
How many times you've loaded brass means almost nothing.

Inspection results are the only factor I use to discard brass.

I have chucked brass after 19 loads and some brand new never fired. Check for cracks or bad rims or wore out primer pockets or anything else safety related.

If it's good, then it's good.
Annealing helps but I rarely anneal and only full length resize if necessary.

Brass life will vary. Just keep up with inspections.
 
I second doing the inspections regularly... rather than basing on a specific number of times.

Enjoy,
