I gotta say you made a good decision going with a RRA trigger. I find mine to be really good, a great trigger that is light and consistent with a clean break. I am sure there are better triggers out there, but I am happy with mine and can easily stay under an inch at 100, with factory ammo.
Now, if you want to really feel great about your rifle run two boxes of federal gold medal match 168 grain sierra matchking BTHP through it. not very pricey, but you might be down to .5-.75 inch at 100, or better. If your gun likes it, FGMM is great ammo with vicious terminal performance on whitetails or hogs. The xm80 is great ammo for longer range days, and stockpiling. I was surprised by how accurate it is for a FMJ.
Happy shooting sir!
