I've got an Ishy where upon firing, the bolt rides up enough (about 1/3 to 1/2 up from from closed battery to reaching the angle cut on the reciever that springs the bolt open the vertical) to raise concern about the bolt coming unlocked and flying back.

The bolt lockup is tight, no headspace problem signs with factory and handloads, but I noticed the engagement surfaces of rear of bolt handle and front of receiver are highly polished. I think that's my only problem.

Ideas I had were:

1.) Replace extractor spring with new one.
2.) roughing up both surfaces with matching horizontal coarse sandpaper serrations for better 'purchase' when in battery,

Any other suggestions or advice?

I'd like to keep the gun, as I've worked up a load that does just over 1" at 100 yrds repeatedly, but the prospect of having the bolt ripping my face open isn't an inspiring thought.
