Any reason I couldn't load a 30-06 brass with the appropriate amount of powder to match .30 Carbine ballisitics, provided I use a 100 grain round nose (plated) bullet?
I am versed in the phenomenon of underloading certain rounds creating detonations, but since .30 Carbine is a proven round, maybe other than the possible need to stuff a filler in the case, why not?
Simplisitically speaking, as long as the primer ignites the powder, it shouldn't make a difference in how big the case is (within reason). X number grains of H110 (in this case----get it?---case----never mind, I'd starve as a comedian) combined with a 100 grain bullet, should produce the same results whether the combination is contained in a carbine brass or a 30-06 brass, right? ( I do realize the longer barrel will, I mean should--increase muzzle velocity a little, but should still be well within pressures below what a 30-06 produces.)
What say ye? (My web-fu didn't help)
