I have 2x 6.5 saum, and soon to have a 257 saum. I like its efficiency and performance adg brass is a big plus. Here's what the 6.5 prc has going for it, 6.5x284 and almost 6.5 saum performance in a saami standardized short action layout that has quality CHEAP ammo available over the counter. I personally think it will succeed, not creedmoor takeover but it'll do well enough with Hornady, Ruger, GAP, and the internet/TV/gunwerks commandos saying it's the best thing ever. A friend of mine picked up a sauer 100 in 6.5 prc, swapped out bolt stops and.mags ala Tikka style, and can now load as long as he wants, but guess what, the eld-m and eld-x ammo both shoot ---- near half moa, sometimes better, with acceptable ES for 800y which is where a 6.5 bullet in 6.5# gun should probably draw the line anyway. Hate all you want, but there is no mass commercially loaded round that pushes the performance thise case does. Yes the 264wm beats it by a bit, but how often do you see quality ammo for that? 6.5x284 runs with it, but nosler ammo for it is 60$ a box. 6.5 rem mag is gone, 6.5x68S nowhere, 6.5 saum, SS, SST, all wild cats, can't get ammo but from say maybe copper creek MAYBE. It fills a nitch and does it fairly well. The 300prc however is trying to fill a nitch that isn't there. 300wm,300wby,30Nosler,300Rum,300 norma all do it, or better and ammo is all over the place. That cartridge will fail quickly I feel, or at least it should.
