You know what? VV N140 is lights out again, and so is the Precision Rifle load. Both are top loads with both guns.
This is a consistent pattern. Generally, what is a good load in another Match rifle, is also good in pretty much "any" similar rifle, especially match rifles with same barrel length.
This RRA NM has a different chamber than the WOA Shilen, and is generally ~20 FPS slower with same load, even though its 20" barrel.
Notice how good the Accurate 2230 22 grain load is. This is one of the best loads using ball powder, you can do in an AR15, period. It just consistently performs, over and over, out of many AR15's.
Benchmark 22 grains also consistently performs. That 1 flyer hurt group, but look at the stacking.
This was all in variable 6-9 MPH wind, during on and off rain storm. And these groups are great
