I employed the 6.five×forty seven Lapua muzzle velocities with the Berger 140gr Hybrid from our check, and even used the Custom Drag Curves for that bullet (which in my knowledge make the predicted ballistics align Pretty carefully to the real-globe outcomes). I’m unsure what focus on distance you shoot at, but we’ll presume an even one thousand yards to essentially make any variations in muzzle velocity stand out. Listed below are the final results:
That was enlightening for me at the very least. I wager this can vary with the large amount of primers you will get … regretably. So I’m not sure how universal my effects are.
Very appealing. I’m not a benchrest man, so it’s good to really know what Individuals guys are executing. That appears to healthy what I’ve read, as well. It’s an interesting little Activity!

I do shoot at temperatures that happen to be various than I zeroed, Despite the fact that I Look at my zero really often … so I assume that boundaries that to a degree. I mainly shoot at fifty five-95 degrees 90% of enough time, but when I’m looking which could be as low as 10 degrees or at a summer-time match, I might shoot in temps as high as a hundred and five.

That’s a terrific issue, Kasper! In the barrel test I executed just lately, I measured chamber temperatures around a twenty spherical rapid-fireplace string (all fired inside 1 minute) plus a fifty round gradual-fire string (fired over 20 minutes). imr 7977 in stock The temperatures I recorded weren’t as substantial as you might think they'd are actually. Even within the swift-hearth exam, the highest chamber temperature I discovered was 149° File. Now semi-automatics would likely get Significantly greater, but this was all performed for bolt-motion rifles and twenty rounds per minute is a fairly rapid fee of fireplace.
So I imr 7977 in stock loaded some 270WIN with IMR 7977 according to a conservative H1000 demand and took them out and shot them.
