My At-one is a 24". For two reasons (1) it was available and (2) its easy to cut it shorter than stretch it longer.Of course the premise of the test was to see what effect barrel length had on 22lr performance. It was not set up as an ammo test per se. I thought that as the testing was done over a week results may not be repeatable (one of the tenets of scientific method) and should have ideally been done in a controlled environment (indoor range). This authors testing suggests the 20.5” barrel may be the ideal but not for every ammo.
I just thought it interesting that during his testing the Blazer significantly outperformed everything else he used.
I was looking for objective data to decide between 16”, 20.5” or 24” barrels which I don’t think he definitively answered but I an leaning towards 20.5” for my 22lr (as long as Mrs B2V doesn't find out).
When I order a Kidd barrel for a tac-sol, I went with a 16.5" to keep it a little more mobile. It is now a part of Kidd build.
While a 22lr seems to have pretty much burned out its powder and pressure around 16", the
Like everything 22, the conclusion is Yes, No and/or Maybe....
