I was thinking of using my POF P308 for the next ELK hunt - but consider the velocity marginal at best for the long 250 - 350 yd shots that might be required.
I am getting 2578 with the 20 in barrel with factory Hornady ELD-X 178 which surprised me as it is only 22fps slower than the factory specs in a barrel that is 24 inches (it should be about 100fps slower)
I ran across the load data on the Federal Website for the new Edge TLR 175 that lists Max velocity at 2803 - if that is accurate I would be getting in range of a 300 WSM. Problem solved.
I have searched here and seen all sorts of conflicting opinions on the temperature stability - Alliant says it is stable and other posts have it at .5ps per degree. The temperature swings a lot here in Colorado so the indoor range I shoot at for load development is about 70 F, while the shot in second season could be anywhere from 10 - 50 F. Also other powders like the factory Hornady which is unknown might have similar variations - (I imagine besides the Alliant the Hornady Factory recipe will be hard to beat) - Also POF advises against Hornady SST ammo in the piston gun for some reason related to the location of the gas port and I am not sure whether this is a factor here.
I cannot solve this mystery now as there is not powder and am starting to think we may never see powder and ammo abundant again.
Is there a downside I am not seeing or is this a case of a free lunch on the extra velocity?
