Scott, Both of these rifles should produce similar accuracy, it's just that one has stainless/fluted, and one carbon steel, the stocks are a bit different in that the P model has a palm swell, but nice wide forend, which sits really nice in the bags, I've got the stock on my 6mmRem and it feels a bit different than a conventional varmint stock like the SF model, you might want to look at the Sendero in 300WM also, conventional stock and no fluted barrel, buddies got one of them and says it shoots 1/2" at 100yds. If you have a chance to hold each model at the same time, that'll be the tie breaker, If you need trigger adjustment help with the rifle you get, let me know. Jay

GA - A few years I picked up a 7mm mag Sendero - I've been very pleased with the accuracy with some factory ammo and with several handloads.

The barrel does tend to foul quickly, and when it fouls, accuracy goes out the window. Have only shot the rifle to 600 yards, but it performs well at that range.

I'd pick whichever one has the stock that you prefer most. Regards, Guy
