In general, its best for any milsurps to be kept to rounds that are around original spec or lower. 1903A3's are 70+ years old now and you don't necessarilly need to keep pushing the envelope.
With that said the 1903's are based on the Mauser 98 action (though not quite as strong), meaning it is one very tough cookie. I do know several people that shoot high powered rounds and have no problems, I just choose to proceed with caution. Just my two cents

The ammo chosen to be fired in a M-1 Garand has to take into account its gas action characteristics. The operating rod WILL be bent with powders too slow for its action. The gun WILL blow sky high if a too sensitive primer is chosen for its ammo, due to premature detonation of said primer. Uncle Sam knew of these two problems and designed his G.I. Ball ammo to allow his Garand to shoot well, often and with safety.

I still feed my M-1 Garand carefully crafted handloads that produce accuracy as well as avoiding the above two issues.

I am not particularly concerned with running modern U.S. SAAMI-spec in an .03-A3 that's in excellent condition.
