Seen that myself with a marlin XL7, I handloaded several types of 130's and was getting decent accuracy but not exactly what I was looking for. One day while at the range trying loads , (i was about done), I had a box of Winchester Supremes (something like the mrx) in 150gr shot 3 at the target and presto 3/4" group. Its done better since with a clean barrel, sold it to a buddy and hes happy with the little tack driver.
