This chart is several years old, so not all the different ammo brands are listed. Just thought someone might be interested.

Randy, where did you find this chart? If you can recall, I'll go there. My old eyes can't read the fine print.

I'm guessing the speeds listed must have been shot at high altitude. As I recall, speed of sound at sea level is about 1080fps.

Larry, dont feel bad, I cant read it either. What I do is 'right click', 'save image as' and put it on my desktop. When I open that copy on the desktop, I can enlarge it and get it big enough to read.

Sorry, I dont remember where I got the chart. I've had it on my desktop for several years and just thought this morning that someone might be interested in it.

Here’s some...

And here some from different barrel lengths, and firearms.

That's a good one. Thanks

Webster, ya got it a bit skewed and mebbe backards....... Sea Level w/ISA conditions is 1116 fps for Mach 1.

More than a bit it seems. Open mouth, insert foot.

Ol' Chuck Yeager fast but not as fast as some think.

Looked over that link you sent me and had the same thought about Yeager.

For whatever it might be worth, I've been running some LR stuff over the Chrono of late with barrels 18-26" long. Most of the advertised velocities for the ammo I've been shooting are consistent with what I see on the speed-o-meter, roughly +/- 10 fps with but a single exception, Norma Tac .22. It claims 1100 fps but shows an average of 1005 fps for three different rifles to include a 10/22, and two Rem 513s

This includes:

CCI SVHP
CCI SV
Wolf MT
Wolf ME
SK Standard (same as Wolf MT)
Fed Auto Match
W-W Power Point
