I haven’t played around much with 130 gr. bullets in my .270 Win, just because I started reloading for it during the pandemic and I bought what bullets I could find. Like my .270 WSM, I get great accuracy out of 140 gr bullets in it. I have some 130 and 150 gr BT’s but I haven’t loaded them as I o my have a single box. 140’s I have plenty. My best load to date though is with Berger 140 VLD Hunting ulcers and Magpro. I get ragged 5 shot groups with it. I worked up a load with 150 gr. NOS ABLR last year that I haunted with using IMR 4831, but I only got 1.25” at 100 yards on a good day. I passed on the line caribou I could have shot with it. I may play around with seating depths to see if I can get it to at least a 1” group. The 140 gr. Nothing bigger than 3/4” though and I like that.
