From a 12” barrel.....

Will it ever make it much ahead of the .401 or .41 GNR’s? Maybe with heavier bullets like that 250 gr it would do a little better. Out of a rifle you could certainly get full burn of proper powders. I suppose it would be neat to plunk in a long straight cartridge kinda like a mini nitro express lol


Certainly would make an interesting study in efficiency........ .401 vs .400 finding where the threshold of barrel length/velocity gains lies
