Well,I just fired a group this morning with 120gr Hornadys that was fantastic. 3 in a bug hole nd a wide flyer that was most likely the opperator. All from a semi custom 284 Winchester long action on a trued 700 Remington. 24" Shilen stainless pipe,B&C Medalist, Holland lug and Leupold 6X-18X. The charge was 50.5gr of 4320 in a Winny case and Fed primer. I don't have the pic in this computer so I'll have to post it later. This rifle was built around the 150/160gr bullets. With the base of a 150gr nosler flush with the base of the neck you are in love with the lands. I was VERY surprised these shorter slugs shot so durn good. If I make it pronghorn hunting anytime soon this will e the combination.
