Gawd I hate no trace, no splash shots. May as well take a bullet and throw it in the trash can lol. What brand barrel is shooting them well?I have had very good luck with it I have a few posts in this thread with load data for it using RL26. My barrel was not chambered specifically for the flatline, I am actually jumping a long ways, need to look but its the most jump I have ever had. My die stays set the same for 230 smk at .015 jump and gets me exact OAL that Warner recommends 3.765" and shoots very well probably luck but worked out well.
Have not shot many flatlines as spotting was more than a challenge especially early this spring when it was wet. I could probably get a bullet splash now to kick up some dust but if it wasn't on steel first round it was a guess where it went most of the time.
