This .270 stuff is interesting to me, as I just got a Model 70 in a trade and it is a great shooter, even with an old Bushnell scope on it and shooting Hornady Whitetail factory loads.
Regarding the 140TSX/Ramshot Hunter load I referenced above. Excellent accuracy in 2 M70 SS Classic FWT's, 2 M70 factory FWT Winlights, a blued/wood M70 FWT Pushfeed, a 1st Gen Rem 700 Titanium, and a M70 Extreme Weather.
