Been shooting 58grs n120 and a 200gr sst in a light blue sabot for 10 plus Yeats. Every year I say I'm going to go sabotless but I always find it hard to walk away from a consistent load. Last year I had a little trouble, but it turned out to be a dirty tungsten bushing in my breach plug. Left it loaded since last year. Fired 1st shot, then another, @80yds then decided I'll pursue a sabotless load next year.
