7rem mag fast twist vs 7 PRC

[OpsMan]

I am looking at a Seekins Havak PH3. I can grab a 7 rem mag for roughly $250 cheaper than the PRC model since it’s been discontinued. The 7 REM mag is fast twist (1:8) and the mag length is long enough to load out to 3.5”. Anyone have any experience loading a fast twist 7 rem mag and any experiences that anyone has that would be pro/con of going that route vs the PRC. I’m worried about clickers also with the PRC. Is the belt that big of a deal? I have seen some videos of Reloading Weatherby on YouTube getting some high velocities out of a fast twist REM Mag with N565/570 and a fast twist barrel. I do reload.

I have a Seekins PH2 7 rem mag , 1-8” 26 inch barrel that pushes 180 eldms 2925 around .5 MOA with H1000. No issues at all with brass or pressure. Using Petersons brass. With my 7 PRC, Gunwerks Nexus, I only get 2875 with a 24 inch barrel and reloads. It’s a tad bit more accurate.
