|...however not closing the bolt completely will DEFINITELY cause a weak strike on primer,at least on modern cock on opening bolt guns like the model 700,77,or 70 to name a few. If the bolt handle is not lowered completely, upon firing the cocking piece will slam into the camming cut on the bolt body instead of traveling forward unimpeded. The striker will have to finish closing the bolt before the firing pin ever touches the primer taking away much of its force.|
I had never thought about that before, but you are right. Aren't we talking about two separate things that are part of the same action, though? "Short stroking" is cycling the bolt too little to pick up a new round and chamber it, but isn't not fully closing the bolt called being "not fully in battery"?
It is very likely that NFIB occurred during the stressful situation you found yourself in, resulting in the conditions you described, and not ammo or any flaw in the gun... except for the second try you gave the round. That is puzzling.
Then the question raised its head: In the older, cock on closing actions, and I'm not sure which those were, was the camming surface set up opposite of what modern actions are? If so, with a failure to completely close the bolt, it seems that the striker assembly hitting the camming surface would knock the bolt open, and if the round fired, the bolt, brass, and gas would be blown out of the action, back into the shooter's face.
It has been 50+ years, but I faintly remember ads for kits to convert the old bolt actions to cock on opening, and new guns advertising the fact that they had the feature. I can remember thinking "I want that. " Maybe this is a safety feature that was/is not widely known? The gun makers quietly fixing a rare, but serious problem?
What do you guys think?
