Ok. So I recently started reloading for my Yugo M48 Mauser, and am looking for the opinion of the learned folk here at THR. I'm a bit concerned about possible high pressure signs in this brass.
First, here is the load I'm using:
Rem Brass
Hornady 150GR SP bullet
47 gr of Accurate 2015 (max load per manual, happens to be most accurate)
CCI 250 primers (large rifle magnum)
Seated slightly long at 2.950" (instead of the min 2.940" listed)
This is the load listed in the Accurate 2004 loading manual.
Here's what I'm seeing on the brass that causes concerns. Vertical lines appear on the brass after firing. Some of them are apparently being caused by the bolt moving across the top of the brass, others may be due to burrs in the chamber. Included are a couple of pictures of the brass.
Also, ALL my primers are flattened. No primer flow, no cratering around the firing pin impression, but I've also heard that the chambers on these rifles can be a little loose, maybe contributing to the flattened primer?
Finally, the brass were all trimmed to 2.230". Not much stretching going on, many only 1-2 thousandths, a few as far as 5 thousandths, but no more than that.
Am I good with this load, or do I need to try to find a combination that has lower pressure while maintaining accuracy?
