Arisaka rifling

For one thing, Metford rifling was, for some years, used in all the MOST accurate rifles. Britain adopted it in a 7-groove style and it didn't work out too well, but the Japanese only used it as 4 rounded grooves and it worked well enough for them that they kept it 40 years.
Looking at the muzzle of a Type 38, you see that the bullet is a rounded square by the time it leaves, but the barrel works almost no matter how much it's been eaten out.
The famed H&K rifling is very much a development of the Metford and it works.
If you don't have sharp-cornered lands to GET eaten by flame and pressure, then they DON'T get eaten by flame and pressure; whole thing just washes out from the chamber forward but you usually have SOME rifling, anyway,
All I can think of. SMLE or Number 4 STILL beats H&K for accuracy from what I've seen.
