Cooper Challenge: 20 Shots 20 Seconds 20 Inches 1,000 Yards

The accu-shot is OK for what it was designed for - a rear support that follows the weapon. It is not preferable to a rear bag, though. It tends to bounce some when the rifle is fired, incrementally increasing the followup time between shots. The accu-shot is great for LEO marksmen who must transfer locations quickly, but if you aren't in a hurry jumping from place to place, get yourself a bunny bag.

TechBrute:
Good point on the monopod vs. the sand bag - especially for this purpose.

Raz-O:
Earlier, I included a note about the Portuguese ammo:

I recently read that there are differences between lots. Frankly, I had never noticed. So today I shot from two of the four lots I have: 79-59 and 81-48. Were they different? Yes! One was just over 2" (the picture above) and the other 3". The problem is that I did not notice which magazine I used each time! I loaded each of the two magazines with only one lot type, but when I got done shooting, I realized that I did not know which magazine I had used each time. Sorry - I'll watch it next time.

And you wrote, in part:

I may have been the one to start mentioning differing quality in lots of portugese surplus 308.

I went back to the range this past weekend and was able to duplicate the results, AND noticed which lot was which:
The 2" group was from the 79-59 lot, and the close to 3" group was the 81-48 lot. Now that I say this, I realize that I should have also kept track of the magazines, as it is possible that they may have some effect. Oh well, next time.

I've never believed that different magazines could affect group size in centerfire rifles. Perhaps differing group centers by maybe 3/4 MOA, from some minimal *possible* feeding differences causing tiny meplat dings, but the bullet nose and ogive are far less important to accuracy than the bullet heel...
