Any one running heavy for cal bullets in there 270 WSM, I have A couple boxes of Matrix 165 gr I want to try, and looking at the 160 partion less a couple grains as a starting point,
Before any one asks, if it won't shoot heavy cal bullets, I am dumping it, as have several others in the 120-140 bracket, (7x57, .264 win, .260) if it wasn't a M70 EW I would likely not bother, but M70 fit me well.
Any one loading this cal heavy,
 
I don't have a lot of experience with heavy bullets in the .270 WSM, but I did try the 160 Partitions in my Kimber Montana. It was sort of a whim thing, I had the bullets sitting there and a tiny nagging apprehension of what might happen to a 130 Ballistic tip launched at 3400 if it ran into some unlucky critter at 50 yards. A dual loading didn't seem out of the question.

Since I have a lot of Retumbo I started with that. A quick and dirty workup from the bottom with 1 cartridge per grain from the bottom to a grain or two over the Hodgdons max and shot them all on the same target. The top half of the sequence printed together, and the 2 overloads did suggest that the manual had put maximum in the right spot. Going to the book max I loaded 9 and shot those for group and velocity. 3008 fps average, and a bit under MOA. As luck would have it my rifle sighted for 300 with the 130s printed the 160s bang on at 200. After renaming the crosshairs I took it out to 500 and it holds MOA out to that distance. Since it was only supposed to be a short range bush load in the first place I don't think I'll be working on it any more. I can't think of anything that I wouldn't shoot with it that I would use a 7mm 160 PT out of a Rem Mag with, which would be just about anything really.

Since you're loading at 165 Matrix I'll assume that you are more long range oriented so none of this is likely to be much help to you. I'd still consider Retumbo though.
