while the x47 might be extremely easy to tune, there are quite a few variables that sway things in its favor vs the creed if you only look at it on a surface level...the x47 is pretty much a boutique cartridge, very few really new shooters or new to reloading shooters using it, hardly any factory rifles chambered in it so x47 rifles are generally higher quality, one brass source so reamer variations arent an issue....compared to a Creed that any tom, dick, and harry who just started shooting or reloading can run out and get 20 different low quality factory rifles of all sorts of variations in barrel quality...my 22, 6, and 6.5 creeds have all be hassle free...ive been running the same 6.5 load for 3 barrels now cause it shoots in every one of them
