A couple of threads are going regarding ammo loads, speeds, energies, etc. Thought I'd share...

A while ago, I began compiling factory performance data on .270 ammo. Now, I've only used Winchester, Hornady, Remington, and Federal...but I have 33 different .270 rounds I've charted: velocity, energy, short range drop, and long range. It was a simple cut-n-paste from manufacturer's websites, then reformatting to standardize. The results are interesting, because they provide side-by-side visuals. Now, I know these are factory results and much depends on barrel length, weather, etc. But for those of us who use factory loads, it's good to start somewhere!

I've attached just the final chart for energies. The whole thing is done in Excel, which is nice, because you can easily manipulate the source data to chart different groups, grains, distances, manufacturers, etc. You can also use different chart types to view the same data from different perspectives.

Obviously, there are other makes out there (Black Hills, Fusion, etc) that I did not include. These can be added easily. Also, with 15 min. on the internet, you can substitute any caliber data into the template.

If anyone is remotely interested, I can pass along the whole .xls file. This pic had to be reduced to fit the size limit.

Anywho, here it is...
