Fieldcraft light primer strike: 6.5 CM

[Mike Islander]

First ever light primer strike from any rifle.

Loaded 4 rounds with one in the chamber for a Monday evening hunt. No deer, and I kept the rifle loaded on safety on this solo trip. Camped out and was back in the stand in the morning. No deer, so went to the 300 yard range for a few shots. Temps never dropped below 57F.

All along, original round was in the rifle. Lined up for first shot, pushed safety forward and squeezed the trigger..."dink". Obvious light primer strike and no BANG. Chambered another round. First one had a light dimple on the primer. Shot the next three without issue. Reloaded the first round again and it shot without issue.

Main question is whether having round chambered overnight had an effect on the bolt spring. My physics background says there's no way this could have affected it, especially in the moderate weather. But I'm not a gunsmith. Any ideas? My best guess is just that my boat is a little bit dirty and I need to clean it. This gun has probably 100 rounds on it total.

It was not leaving the spring compressed overnight.

Likely cause is firing pin friction or poorly seated primers.

If you hadn’t cleaned the bolt, sometimes they ship with a heavier oil/grease or too much.

can’t say that I’d ever see a single reason to have a round chambered until it’s “go time” on a hunt but that also shouldn’t cause a light strike and it’s another issue entirely…

are they handloads or factory?
