What did you think of the 153.5's. I found they were accurate, but a little slow. Went to the 140's with a similar charge, same accuracy, better velocity, and slightly smaller ES and SD. I worry about the lower velocity impacting the heavier round when pushing out past 1,000 ... but I'm still testing and pondering. Trying not to waste too much in supplies early in that process. Hoping to settle on "the perfect 6.5-CM cartridge" prior to heading to Utah for a long range clinic in a few months. Also deciding on the right ELR rifle (300-WM or 300-PRC) and the right load for either/both of them to stretch to 2,000-ish during that clinic. There's a milk jug in Utah at 2,000 yards waiting to be murdered soon.
Any chance you'd share your favorite 153.5 load data?
