The 270 is my all time favorite. It was my first gun and it’s on its second, almost third barrel. It’s the one that feels the best with everything. Everything like reloading, walking, shooting, getting past fences, & in and out of the truck. I bet I have over 10,000 rounds shot in 40 years and I’m putting much more through it lately. I try the usual powders like H4831&SC, R22, R19, IMR 4350, MRP, & 7828. I usually use 130 grainSPBT and 140 TSX. I haven’t tried the newer powder like Stabill, Big Game, Superformance, or others. I want to, but never tried the Vhitavorhi powders. The best yet is H 4831 or IMR 4350 and they do so well that I may not ever try the others. If a 270 does poorly with 4831, it’s probably a bad 270 and needs to go away.
