Headspace gauges

[72 usmc]

can I use the same headspace gauges for both

Yes, and use .074 gauge. You may also have an oversize chamber, read the brass after it is fired. Shoot the first round in the sled or set of tires if unsure of the rifle, away from your face
Let us know how it checks out, most Enfield with matching bolts pass a FIELD (.074) American terminology or the British No Go (.074) terminology. See Alans remarks in the links. Buy one gauge =.074

A really nice but expensive set: https://www.tectal.at/en/lee-enfield...sh/lee-enfield
