Nosler 300 WM brass

[bpotter]

Anyone have any problems. Been good in
280 AI but have a batch 300 WM of that needs a big shoulder bump after single firings with moderate loads. Will see how primer pockets are after 3rd firing. Hornady factory reload brass no problem. Have ADG brass I can try but have been hoarding it.

No, I am on 3rd shot and have had no issues

Might have a soft batch/bad run... or something else is wrong. Will see if these are re loadable after 2 shots but suspect many will not.

Found the problem. It was not a shoulder bump issue.
Some cases were swelled above belt. Might have been a pressure issue but that was only sign.

FL without bumping shoulder back seems to have solved it. The offenders have been relegated to fouler loads only.
