Pulling the bullets on a factory case, bit more risky but should work for that ammo. Using a proper headspace gauge ensures SAAMI spec on headspace so that any factory ammo should chamber.
Using factory, or sized brass, could limit the ability of other ammo to chamber properly.
When using brass to set headspace be sure to completely strip the bolt so there is no resistance. Unlike a hardened steel gauge, it's easy to deform a brass shoulder by a few thousandths with too much pressure and cause an inaccurate reading.
JMO, YMMV.
