When looking at the 270 WCF, 270 WSM and the 6.8 Western, I see no advantage from one to the other. If all run an 8 rpm, what’s the gain. With 24” barrels, the WSM is approximately 100 fps faster than the 270 WCF with 130-150 gr loads. The Western produces even less velocity than the WSM. All that’s needed is a comparable barrel twist rate and none is really any better than the 270 WCF. In fact with its std long action length you can use the longest high BC .277 projectiles (175 gr) on the market thereby utilizing case capacity more efficiently with less muzzle blast than a hindered 3.00” COAL SA magnum. Another benefit is the 270 WCF’s ability to create impressive velocities with a 22” barrel and a 6lbs rifle which makes for a better alpine/mountain carry firearm. Lastly, the WSM cartridges are slowly dying on the vine, the Western was never really popular to begin with and is already dead in my opinion. The 6.5 PRC is extensively more popular than both magnums are. If .277 is your thing, rebarrel to an 8 rpm and go for it in a 270 WCF. Even with a 10 rpm neither .277 SA magnums comes close to the 270 WCF reputation on killing game, it’s been out there doing it for 100 years. Only one man’s opinion.
