Took the RTI Mora in 25 cal out to shoot 100 yards today with AEA 29.6 grain pellets. After having only marginal success with the 33.9 grains, I decided to jump to a different pellet weight. Well, you gotta love it when a plan comes together. I decided to use the same basic settings as I had been playing with for the 33.9 grain pellets. The problem I had with the 33s is that they would randomly throw a flyer or two out of about every 10 shots. When I say flyer, I mean they would drift off my POA by anywhere from 1/2 MOA to 1 MOA which in 100 yd benchrest is as much as a 2 point drop in score. This happened consistently regardless of the speeds I tried. Every tune I tried from 900 to 970 fps would throw these random flyers and they were truly random without any consistent pattern. These are the same 33.9s that produce incredible consistency when shot out of my Skout Epoch .25. But, for whatever reason, the Mora simply doesn't seem to get along with them, so I jumped down to 29.6s not particularly hopeful that anything would change. Boy, was I wrong. The Mora and these 29.6 apparently have a love affair that I couldn't have guessed at. Although I'm not particulary impressed with my standard deviation numbers, I really can't complain considering the POI results.
It appears that the 975 tune was the optimal number in all aspects
All of these use the same 120 reg pressure and the differences were tuned via the dwell valve adjuster.
Target #1 scored as a 238 @ 8X @ 975.3 fps 3.2 sd
Target #2 scored as a 235 @ 2X @ 978.7 fps 3.6 sd
Target #3 scored as a 231 @ 6X @ 981.2 fps 4.5 sd
*** It's important to remember that although I'm considered a decent shooter, I'm not anything special so my results can pretty much be expected by anyone who shoots with any regularity.
