I don't understand it but I hated the 300 R and really like the feel of the 250. Extra weight on the barrel I guess. Sure is a shooter.
I'm so glad you didn't like your .300 R. The one you sold me is a shooter. First group at 100 yards with an old El Paso Weaver 4x and factory 150 grain corelokts was .68" for 5 shots. Unbelievable accuracy! All I did was shim the front base to fix alignment.
The .300 R has become desirable to me!
