Nimrod Wrote:Ive got a LBC with a 20 bull barrel. This rifle typically puts five in the same hole at 200 yards. Suddenly the groups have opened up to 1-1.5 with known proven loads. Barrel is clean, no copper. Everything is tight. Ive got probly 3000 rounds through it. Swapped scopes, 3 times. Dont know where else to look. Cant believe Ives shot the barrel out yet. Could it be bolt fatigue? No visible cracks or anything but it does appear to be slightly stretching....if thats even possible. Just looking for advice.
One hole at 200 yards is typical performance?
I imagine the 200 yard bench rest record is something like one hole at 200 yards but it wasn't typical and wasn't shot with a .264 LBC or a 6.5 Grendel or from anyone on this forum.
Most guys who are really good marksmen here admit that half a minute is somewhat a rare occurrence with them and you are complaining that your rifle is poor giving 1/2 to 3/4 minute performance all the time at 200 yards?
A Bench Rest shooter with a lot of competitive experience and knowledge of equipment would say his barrel was shot out.
My bet is that you have a damn good rifle and gear and that it is doing exactly what high quality gas guns and gear do. Hold about a mean of about one minute at 200 yards with an SD of about 1/4 minute.
