.38" at 50 yards is .76 MOA.
Remember - 1" (1.047 technically) at 100Y = 1MOA .5" at 50Y = 1 MOA
That's still excellent. These rifles put factory ammo sub-moa. When you get a load right for it, look out baby. I tell people that the SPR and my FS2000 are made by Santa's expert chocolatier elves, stationed in Belgium. When they're not making chocolates for Santa, they go across the street and work for FN Herstal.
As far as the DBM, no issues at all. I can slap mags in and run the bolt as agressively as I want to. The followers have a lip in it that suits single loading as well. Just drop it in there, and it's automatically guided so that the controlled round feed picks it up every time. You don't even have to watch.
The only time I had feeding issues was when I loaded some 175's extra long in search of the lands. They went into the magazine, but didn't have enough clearance. That was my bad, not the rifle's.
In competitions, I'm trouncing people with very expensive custom rigs with an off the shelf rifle. This has been unquestionably one of the best firearms purchases I have ever made.
