The second part is mostly true but not the first. If I recall correctly the 6.5 Creedmoor sat dormant in sales/popularity for a few years before it caused a brushfire of fans and equal hate.Very valid because for some reason any and every mention of rifles in the last 6 months to a year, somebody gotta pipe up with “ackley improved”. Kinda like when the 6.5 first came out, somebody always had to pop up saying their 6.5 CM was better.
This is all somewhat satire, but truth is most (not all) mouths piping up about ackley improved, don’t shoot or know enough about it for what little little they gain to ever make a difference in the performance of whatever gun they think needs to be AI’d……………
