The fixation on stock fit, LOP, drop, etc seems to be a British thing carried over from shotgunning, where it is important.
English Sporting Rifles from 1810 or 1820 seem to look pretty much like their fowlers. Flat buttplates, single triggers, similar lines, etc. As though snap shooting was the purpose of a rifle.
American rifles from 1810 or 1820 have wicked crescent plates, double set triggers, long sight radius. As though precision were the point of a rifle at the expense of snap shooting.
And it’s funny how that remains true. London rifles emphasize stock fit and being tailored to mount quickly, I guess to face tigers and elephants from 10 yards. That’s all that matters. Americans are fine adapting to an off-the-shelf stock but want tech features to hit an elk’s ear-hole at 600yds. Completely different priorities.
