I took my 243 Ultra bull barrel out this morning along with my Marlin XL7 3006 to a range in the area. My 2 best groups were on the same target. The larger (H414 46.5 grains and 58 grain V-Max bullet) of the two was 1.125" @ 80 yards and the smaller (H414 47 grains and 58 grain V-Max bullet) one was .69 @80 yards. The range says 100 yards on the NRA sight but I walked it off several times and came up with 80 yards every time. I am happy with the smaller group and think I will load up some and use that as my varmit load in my 243.
