I've never heard of similar problems with the Metford/Enfield Riflesicon of the same time period.

A few differences at work:

*The .303 Britishicon round, being a rimmed case (which offers a natural seal/vent shield), does not have the same risk for gas venting.
*The M1903 design leaves part of the case rear unsupported, enhancing the potential for a case failure in the event of weak or damaged brass. (Supposedly this was later resolved by a change in the bevel angle to the chamber face on new barrels, slightly lengthening the chamber?)
*The original M1903 design has woefully inadequate ability to vent gases in the event of a case failure. One small vent hole in the right side of the receiver ring, with matching holes in the extractor and one locking lug, all of which are prone to plug up with dirt, grease, and/or cosmolineicon. This caused case failure gases to expand into the receiver ring and bolt body, which were obviously never designed for "outward" expansive stresses. The larger "Hatcher hole" on the left side of the receiver ring, added to very late production of new rifles, and drilled into some older receivers, was a major improvement here.

Contrast that with the Mauser 98, with two nice big vent holes in the bolt body to vent gases out through the left bolt lug channel and thumb clearance of the receiver.
