I use the Waters in the Super 14" barrel...
I started using it in about 1988 or thereabout and the first bullet I used and stayed with until it was discontinured, was the Hornady 120 SSPSP and 32.5 grains of H-335...
(I still have a full box--100--and about 30 of them left in an opened box)
Since that bullet has been discontinued, I tried the Hornady V-Max in 120 grain...
Might actually shoot a bit better than the original SSPSP bullet...
Still use the H-335 powder and a CCI-200 primer.
Most always 0.75" groups or less at 100 yards and mostly at or near 1.25" at 150 yards...
Shot several deer, all less than 75 yards and both bullets performed well...
That's my choice and I ain't gonna try anything else...
Good-luck...BCB
