Before I would answer that question would want to look at the bedding job. If the 1922 stock is not well bedded a single full power 30/06 round could crack it. If it's bedded well may handle factory ammo fine.

My pratice is never shoot full modern loads in any old gun, due to the wood not the metal. Lot of guys shoot modern cheap Promo shot shells in nice old SxS's and crack stocks doing it. I load low pressure moderate loads for old guns. Never cracked a stock.
