Poor consistency on bore diameters, maybe? .247" is not bad for a .249" groove diameter & likely shoot just fine.
My old 9.3x57 had .370" groove dia. and still shoots all bullets from 225gr. to 300gr. & from .365" to .367" bullets into 1 1/8" or better at 100meters - most weights are under an inch.
Yep, undersized bullets can do just fine. My R.B. Rodda .404 Jeffery (circa 1929, probably by Schüler) has groove to groove diameter of .4285" and shoots just fine with standard .423" Woodleigh's..........
