I also think the GPR is a very good rifle. I have one in .50 that I bought new twenty years ago and learned to hunt with it. For something made by Investarms, they're pretty good. I would rank them high for a production gun. I also use the pillow ticking only - .018" thick. I lube with Wonder Lube but I used to use Lube 109 - in my opinion, the best stuff there ever was. As far as accuracy goes, I get about a 4" group at 100 yards. Some will do better but since I usually won't hunt that far, it doesn't matter. My hunting range has usually been under 80 yards and I've been very successful wirth that rifle. I use BP only as Pyrodex gives hangfires. 80 grns with a .490 ball. I have alot more to tell you if you need more info....
