So I’ll start from the beginning, I bought this gun off my uncle it’s a late 90s model. It came with a unbrand scope so I changed to a RedField, I had laying around, took it shooting three weeks ago. Got it dead on at 25 yards moved out to a 100 and I could not get a group tighter then 3.5-4 inches. I was all over the place so I checked all action screws that secure the rifle to the stock and action. Still shooting 3-3.5 inch groups. So I figured it was the scope as it was used off a gun I bought. I order a Leopold VX-3 mounted it With new rings and bases and went out to sight it in. Same thing at 25 yards I was dead on putting 3 shots almost touching. Moved out to a 100 yards and guess what same group(3-3.5 inches). I honestly don’t know what going on? I also took my SAKO 243 and put three shot at a 100 yards with in .5 inche. So I know it is not me. FYI there was cleaning( Boresnake) every few rounds and cooling of the barrel to.
