Once you know about rifles and reloading - you find our really fast (or should) that you have to understand the customer / people.
Take a PRS shooter....
6 Creedmoor is a hotdog that will burn barrels in 1,800 rounds, but if you are a good tactical shooter and want to min. Wind drift - it may be your huckleberry.
6 BR is the opposite end of that spectrum, it lasts for every, is very accurate, but it’s a bit slower... older smart guys who looked at the speed / barrel life trade off oftentimes go this way.
6 Dasher - a good mix, requires fireforming... aka lost of time, and some bad necks help or don’t - but if you are a “efficieny” focused guy you might want that.
So always find out what is going to resonate well with the shooter.
Just say’n... Here we could say
Swift -
22 Creed
22-250
