The conditions:
All groups were shot at an indoor range using a make-shift bench rest. All groups were shot at 25 yards. I fired 2 groups per target with each gun, alternating between guns - M4, LT, M4, LT. The top and bottom groups on each target with fired with the LT. The left and right targets were fired with the M4. The center target was used with a few rounds from each gun just to see where they would print.
The targets:
The red target dots are 1" in diameter. All groups for record were 5 shots.







I have been trying to get these 2 rifles as equal as possible so that I could determine which one is the most accurate. I was finally able to get both uppers to run with match triggers. I would have bet from some previous range testing that the M4 would have a slight edge, but it would be pretty close to a toss up. Seems I was wrong! In my case, at least, I’d say the LT is clearly the winner. I expected the CCI Green Tag to shoot the best, but both my rifles seem to prefer the Eley Match. On the last target I was shooting the LT with Wolf Match and had a great 4 shot group going on the bottom target spot. I knew the 5th shot was a flier before I looked through the scope. My bench rest skills aren’t what they used to be.
