Anyone had this work? Been tinkering with n150 as alternative to varget. I know some have made it work well with 109s, but I am struggling with 105 hybrids and 107 smks. SD is 2-3x varget for range of loads anywhere from 30gr (2880-ish) to 31gr (2980+), on the order of 15-20SD. Case fill issue? CCI450 with Alpha brass, ATV4 powder trickler, 266 die bushing. Tried in 2 Dashers (both with 700-ish rounds) and both didn't have good SDs, but shot pretty well (<.5MOA). Tried cleaning, scoped to make sure no carbon ring, etc. Thoughts?

105 hybrids and N150 is my preferred combo, however both my barrels are waaaayy slower than yours, as my 26” CRBs 1/7.5 chambered by TS customs with alpha legacy .154 fb reamer are giving me single digit SD over a 30 shots sample and 2820 fps muzzle velocity. I would start checking your scale first, 105 and n150 gave me half moa at any load between 30 and 31.5 tbh.

One of my barrels (bartlein 1:7.5) is more like 2780. But if I run varget loaded ammo through the same barrels, they both have good SDs. If I run n150, the SDs are no good for either barrel (one at 2880 (Hart 1:7), one at 2780) - if there was a scale issue, I'd see problems in both loads. Both chambered with alpha reamer .120 FB - could be more jump is needed? Jumping .60 today. I'll double check everything because others have great experience like you. Thanks for feedback!
