Yes, the 160 Matrix in a 1-8" twist McGowen. The 160 is the only bullet that's been shot in this barrel and I've been very happy with it and I'm up to 495 shots through the barrel with the 160 Matrix at 3430 fps.
I already had a pretty good idea what load would work so I just went straight to a heavy charge of US 869 and adjusted until I got roughly .5 MOA groups. That took about 20 shots to get dialed in and I haven't changed anything (including seating depth) since. It's still holding .75 MOA out to around 1500 yards which is well beyond the practical hunting range of this combo. Groups would probably shrink a bit if I adjusted seating depth to make up for throat erosion.
