Went to the range today to chrono some loads.    All were 5 shot groups (minimum 3, if the chrono didn't read).  4.25 inch and 5 inch Tisa pistols.  8:15 am, ambient temp around 70 degrees.    Personally, I think Blazer was a secret contender for ball ammo.  Hope this helps someone.   (It's formated properly in desktop view)

Excellent post thanks.

I always liked Blazer ammo and it sure looks the best of that group. Some of those extreme spreads looked awful.

Blazer aluminum always shoots very accurate too and seems to be full power. Also reflected by your chrono data.

The S&B really didn't like the barrel length drop.

Neither did the "service grade."  I wonder what if they were using a different powder or something.

I'm kind of annoyed because I just ordered 2 cases of S&B in 9mm.  Hope it's not as finicky.

But Blazer was kind of the secret winner IMO.  Looks like the Aluminum was probably best 'bang for the buck.'  

I definitely need to do some accuracy tests, but don't have a rest - usually just sandbag it, which isn't super repeatable.
