I recommend...
that you honorably retire the rifle.
My experience with the Spanish '93-type actions is that they are not suitable for rebarreling to any modern cartridge at all.
They are all soft (many years ago, I watched an old gunsmith squash one in simply tightening his action wrench onto it. When he noticed that the barrel shank wouldn't thread back into the action, and realized why, he simply took the receiver out of the wrench, laid it on his bench and smacked it with a big brass hammer until he could screw the barrel back in).
With pressures higher than about 40 KPSI (virtually all modern CF rifle cartridges), the locking lugs will set-back into their seats very quickly, increasing headspace until the bolt becomes hard to open and case heads separate. Several years ago, a customer (and friend) decided he'd like to make up a 7.62x39 rifle on just such a '93 Spanish action. I couldn't talk him out of it, so made and fitted a barrel for him. In shooting about 200 rounds of Wolf ammunition, it battered itself into just the state I described above.
Just my recommendation, but not based on hearsay.
