Re: Who's stretching it out with a 270 WSM?

The Norma is .002 thinner at the neck than Rem brass. I have a reamer set up to turn .003 on Rem and skim the necks on Norma, Norma is also softer brass. I FL size everything and get much more consistency that way but I'm set up so it just bumps the shoulder and sizes just enough to chamber nice. Far sub MOA past a thousand so that good enough for me to hunt with.

    Nothing is softer than Remington brass. Remington is the cheapest brass they can put on the sale table in September just before hunting season. I works at the minimum level for handloading. Look at this metalurgy report. Remington is using the basic copper/zinc alloy it did a century ago. The handloaders market is dominated by alloys that contain iron or silicon or both to increase the case life and allow higher pressures. A friend of mine just went through a series of case separations with Remington brass in his .375 H&H on the second or third firing. This stuff was clearly not made for handloading.

    I need a good load charge for a 270wsm shooting the 175 matrix bullet.

    I'd start looking at around 63ish grains of Retumbo, and work up from there.
