I own several .243's. They have served me well over the years, one since 1969, a Remington 700 ADL.

Shooting the BAR's I feel the groupings are fairly loose, perhaps the heat and bore cleanliness having something to do with it. I always shoot new ammunition. Generally speaking the colder the weather it seems the tighter the groups.

Anyone have any general comments on working with/sighting in the Browing rifling? Thanks in advance, especially the RedNeck Prof who at one time was extremely helpful in this forum.
