Can I have the heaviest bullet possible loaded to 310ms (subsonic) in a std .22lr case please? COL will obviously be longer than std .22lr but that is no problem in the current multicaliber rifles. Just need a barrel with faster twist. This would be perfect with a suppressor and shooting in the wind. I had a lot of success with the old Lapua Scormax 46gr ammo.

You may reference some of Saaed’s extensive tunnel testing of rimfire ammo.

I hope they test the FEDERAL AUTO MATCH. That’s always been, in my experience, the surprising budget .22LR ammo that performs way above it’s weight class, both in terms of reliability and accuracy.

I bought a Sheperd 22 scope twenty plus years ago. I routinely make 300 yard shots. Shooting a 200 yard match for 22LR I was accused of shooting center fire. My Winchester Power Points were still super sonic at 200-yards.

This is nothing more than an advertisement for his new book, all the links I clicked on went to a site selling his book.

Editor: Well… as the article explains, all this testing is being done to provide data for the upcoming second edition of Bryan’s book. That’s stated pretty clearly. It only seems logical to link to the current book.

Perhaps he should just read this?

Plus, calculating BC using two short base-length commercial chronographs? That’s a bit crude. So, no industry standard quality chronograph systems (skyscreens and time measuring systems), no skyscreens set out in a ladder formation, no Doppler radar? Are you making corrections (geometric or otherwise) to the velocities for the position of skyscreens and rifle, the angle of the rifle barrel and the projectiles trajectory?

Editor: Neil, thanks for the citation. I do believe at least one of Bryan’s Oehler units is set up with extended length. Bryan does have a LabRadar Doppler radar unit, but I don’t think it was used for this test.

If you guys get tired of all that testing, I’d offer to volunteer my time to help out. You know, for science and all.

Bc for 22 LR ammo? Why would the manufacturers themselves not write the BC on the box of there ammo? Does is actually matter to know BC for 22LR? From 800 fps to 1640 FPS + . Drop chart seems to me like the only usable knowledge for the use of a 22 or is it?. Are the 22 LR bullet similar enough from round to round to be even able to measure BC? All kinds of questions we will get answers for.
Thanks to the researchers.

This is fantastic news! I’ve been wanting to true up my BC guesstimate in my 22LR entry in AB Mobile, but I wasn’t sure how to do it. I can’t wait to get my hands on those numbers!
