The longest confirmed kill on ANYTHING was done with a .300 Ultramag by Dan Kinneman over in the Jackson area. He managed to grease a Prarie dog at 2200 somethin yards![]()
I didn't know that. Did Dan move to Jackson? He was living in Green River last i knew. Dan helped me with my STW. He taught me a very rigorous break in regiment for it. I stuck to it religiously and i think it has effectively doubled if not tripled my barrel life. I can shoot 50 rounds at 3500 FPS and will barely see copper fouling on my cleaning patch. That is critical with these over-bore magnums. I have well over 600 rnds through my STW and still can maintain tight groups. Last year while getting ready for hunting I shot a 5 shot group at 300 yards that went .458" center to center!
