I agree with the thought that your going to have to do your homework and start shooting some different bullets through your gun to see what shootsbest through it. Even different weight core lokts could shoot better than the 130's you have tried. It is trial and error until you find the right load and brand.
+1.
I tried tons of different ammo in all my rifles, with varied results. Finally, I started paying attention, & realized that each of my rifles seemed to prefer a particular
weight of bullets, regardless of brand:
.30-'06 = 165 grain
7x57 = 174 grain
.243 = 85 grain
.223 = 64 grain
I used to obsess that if I wasn't shooting 220g bullets out of my '06, I wouldn't get the John. C. Holmes-like penetration that I wanted on my elk hunt. Still, with 2½" groups, I wasn't comfortable using 220's on my trip. So, I went with 165's, & the elk got just as dead.
Just from the Remington site, I see they have 100, 115, 130, 140, & 150 grain offerings in .270 Win. I'd check the 150's first, 'cause they'll be cheaper than the premium bullets in the 140 range. Once you find a weight that your rifle seems to like, then you can check different brands. FWIW, none of my rifles seem to prefer one brand over another in their "favored" range of bullet weight.
Good Luck,
