Ok fellas I was able to sneak out to the ranch yesterday for some more load development.
: Norma 270WSM
: Fed 210M
: CEB 130 MTH_G05 LD-HPBT-MAX
5-shot velocity was right under 3400fps with zero pressure signs & a SD of 15fps. Not the best but this is with VIRGIN cases, I would expect that to shrink some with once fired cases. I know I can get more speed, but will it be as accurate?
I think we have a winner so far!
I was finally able to play with my new Magento-Speed as well... What a kick butt little unit! WAY easier to set up & use than a traditional chrony with the wires & sky screens.... I was worried that it might not pick up the Monometal bullets but am happy to report it worked just fine with the CEB's & TTSX's out of my father's 300Winmag. I'm sure someone will get all bent out of shape seeing something clamped to the barrel.... This is the second time I've shot this load, accuracy didn't change but there seems to be a 1/4moa shift in impact if memory recalls correctly.
