Would the cases be damaged when extracted if I left it as is?
Not terribly, certainly the ejection cycle is pretty rough, but the bigger issue is finding all of the cases or at least enough to make reloading them economical.
Why would doing this cause hard extraction of brass cases? So hard that a soft faced hammer would be necessary to drive the bolt open?
During firing, the cases will expand and thus becoming very tight in the chamber. On a bolt action, you've got a large surface area to tug and pull from(the bolt handle), the sks is quite small for large hands and from my experience, it is much harder than hands can handle to extract. I've never done it with any other sks, but my particular sks is rather hard to pull in this case.
Steel cases?
If the SKS isn't for you, then maybe buy a bolt action? If you want a safe single shot, then put in only one bullet at a time. I don't want to assume too much, but judging by your question and the way that is was worded, I think your over your head with this. This rifle is not made to operate without either the gas rod or a hammerI don't think that I am over my head with this thanks. Handloading is a hobby of mine as I have done so for all my rifles. I want to make some 150grn soft points and use the sks for hunting next year, and was merely looking for a solution to a potential problem of overly damaged cases from extraction. I'm sure you meant no disrespect so I won't take it as such.
