I lost the old posting, but I found the results saved in Word, so here they are a year later and with a few edits.
These were 5 shot groups at 50 yards with iron sights. The flyers may have been me, the rifles, or the ammo.
After these types of results I gave up on 5 shot groups at 50 yards as being a reliable indication of accuracy and went to 10 shot groups at 100 yards with a scope for more reliable results. I still need to reshoot these at 100 yards. Some of you may remember the Arsenal M5 was replaced after a later test led to its demise and me taking up pistol shooting for a while.
Now here's what I got last year:
Federal XM193 Lot 032
VEPR – 1" group.
Arsenal – 1" inch group if one flyer is disregarded, 3 1/3" if flyer included. I fired two more targets. A 2 ½" group and a 3 ¾" group resulted, with no identifiable flyers.
WinchesterQ3131A, Lot T632
VEPR – 1 ½" group if flyer disregarded, 2 ¾ if included.
Arsenal – 2 ½" group if flyer disregarded, 2 ¾ if included.
Federal American Eagle 55gr FMJ Boat Tail. Box dated 1996.
VEPR – 1" group if two flyers disregarded. 1 ¾ group if one flyer included, 3" if both included.
Arsenal – ¾" group if two flyers (?) disregarded. 1 ¾" group if one flyer included, 3 1/2" if both included.
Hornady 75gr BTHP Lot 030092
VEPR – 1 ½" group if flyer disregarded, 2 ¼" group if one flyer included.
Arsenal – 1 ¾" group if flyer disregarded, 2" group if one flyer included.
Here is the best target from the test. I need to check if this is reproducible on demand:
