I used to be obsessed by sub-MOA and if a bolt or single shot rifle could not perform as such, it was sent down the road. When I suffered from that obsession, I was fully capable of such performance, shot A LOT, and was OCD at the reloading bench. Our "He Man Woman Hater's Club" had all gone through a "practice wife" and decided a passionate relationship with firearms was safer. My garage had been converted into a gunsmithing/reloading/alcohol paradise. We had multiple reloading presses from Dillon, RCBS, Redding, Forster, Ponsness Warren, a ton of accessories and gadgets, all the tools to build and customize firearms, and a bar stocked with the finest spirits that were on sale at the PX. It was a paradise!
Now days, I am not always capable of sub-MOA even though some of my kit is. Multiple surgeries and my morning liter of coffee habit are not always conducive to 5 round+ MOA. Also, time and experience has proven to me that sub-2MOA is more than good enough for all of my hunting situations. 3 shot sub-MOA is easy enough but 5 shot plus requires a level of dedication and concentration that I do not possess most days.
However, pursuit of sub-MOA accuracy is an interesting, (at times frustrating) and fun endeavor!
