Good to hear from ya Doug! A couple of points.
I've also settled on Varget for my handloads. I own a chronograph and my loads with Varget have given really decent velocities with modest pressure. Regarding factory loads there are several loads other than the Remington load pictured that have also given less than MOA. Federal's Premium loading of the 85 grain Sierra BTHP was a fine shooter. As was the Federal load featuring the 70 grain TNT hollowpoint. Any of these was less than MOA from my rifle, they just couldn't outshoot that particular Remington load.
Regarding maintenance, I know an old fellow who has a Belgium BAR .243 and has killed a train load of game of all sorts with it. He never cleans his rifle! A wipe down on the outside with an oily rag, once every couple of years he runs an oily patch down the bore. That's about it. Craig Boddington once wrote of a guy he knows who hunted the world with a BAR .30-06. This guy claimed to Boddington that he had never cleaned his BAR at all! I'm not that bad, but once a year I do a detail cleaning, after that I shoot the darn thing until coyote season is over here at the end of March.
The trigger isn't crisp and clean like a finely tuned bolt action. But there are plenty of bolt guns with crappy triggers too. I think it's more a matter of what you get used to shooting. Put some range time in and you'll be surprised how well you can shoot an otherwise accurate rifle, if it's a bolt, semi, pump, or lever action, it's what you get used to.
