I bought a Ruger American Predator in 6.5 Creedmore about two years ago. After about a year, I succumbed to the temptation of buying a really nice laminated wood stock for it, hoping to make things better. Well, besides spending half again as much for the new stock, my rifle really doesn't shoot much better than it does with the ugly OEM stock, and guess what, it's heavier now. The new stock does have a higher comb that allows a bit better cheek weld when looking through the scope I have mounted, but I still don't shoot it any better!
My experience with this rifle has been entirely positive. I'm not a really great shooter, and I don't normally shoot at things beyond 300 yards. I do have the rifle sighted for zero at 200 yards which pretty much allows me to shoot out to 300 with little if any sighting adjustments at animal sized targets. I really like this rifle! For me, pretty is as pretty does, and I'm seriously thinking of putting the OEM stock back on the rifle. I have more confidence in this rifle and it's caliber than any other rifle I have ever owned!
I had the opportunity to shoot at a 400 yard steel target for the first time in my life while the rifle was still pretty new to me. I made a slight sighting calculation based on my understanding of the trajectory of the round fired and barely missed the gong my first attempt. I made a second small adjustment allowing for a bit more windage adjustment and hit that gong on my second shot! I was very pleased! I was not shooting from a very stable position at the time either, nor was the weather very good, so who knows? But I still tagged that piece of steel. For what I need this rifle for, it's all I need. And for the money, all I can say is WOW! I know this is just a sample of one, and only one shooters experience, but having many years of rifle experience, I think it's valid, at least for me. Both the rifle and the caliber has been an eye opening experience for me.
