Tormented Souls 2 - Dealing with Spider guys

im still in the beginning areas. and generally the enemies haven't been too crazy. but i am wondering is it smart or manageable to fight the spider guys with the nail gun or should i continue to use the shotgun? i am at a point where i have about 20 something nail ammo and 6 shotgun. im in the other side for the first time and i figured instead of using shotty for every spider enemy, id use my nail gun just to save some shotgun ammo.

of course the only reason im asking this is because nail gun seems to be significantly harder challenge compared to just one shotting with the shotgun then finishing with hammer. i need a good deal of space to use the nailgun so i can stagger them before they reach me.
