[QUOTE="RockyMtnMT, post: 2192822, member: 7999"] My guess is you have a tight bore. This has always been the problem for copper bullets. They are harder than lead so they will show high pressure in tight guns and poor accuracy in loose guns. We designed our patented PDR drive band bullets to solve this issue. Because our drive bands are on a radius the outside diameter of the band is very finite resulting in very little bullet material making contact in the barrel groves. Being a radius as the rifling engraves deeper it gets more material to engage. Between drive bands the valley is deeper than bore dia leaving space to deposit engraved cooper. This allows us to cut our bullets at .0005" over caliber without increasing pressure tight bores but still sealing loose bores and producing superior accuracy in all. For your wsm our go to has been the 166g Hammer Hunter. They will fit nicely in the short action and run about 3200 fps. They will handle the job on the African animal very well. Brian just took a gemsbok at a bit over 200y with his 270 Sherman Short running our 140 Hammer Hunter one shot no tracking. We will guarantee our bullets to do everything you expect or your money back. We look forward to being part of your hunt. [/QUOTE]
