Mosin-nagant heavy bolt lift
I've got a bunch of mosins, and am trying to make at least one of them into a decent shooter. Seems that the best looking one has the heaviest bolt lift, and the biggest dog cocks like a well-tuned model 70. Tried the obvious, swapping out mainsprings, which had no effect, swapped bolts and the easy-cocking one stayed that way, and vice-versa. So the difference is in the bolt, which makes sense. But not the mainspring? I hesitate to swap bolts around, assuming that the importer fitted the correct headspace bolt when they were assembled. Maybe not.
So-any ideas on how to reduce the (sometimes excessive) heavy cocking effort?
