4198 can be a "great" powder.IME,and am using right now in my 7-08,.....it has a narrow'ish band for accuracy.Find the node through testing and it's mucho joy.Let the weather change,or change something in the rifle,or otherwise disturb the tune and you're looking at the powder with that cockhead dog look.
I found it gives VG accuracy in .223,and 22-250.The recoil pulse is a little "snappy",vs a much more gentle push/shove if say,4895.Meaning,have a lite rig shooting off too tight of fr bag,and you have your hands full.BUT,shot from field positions,things can be different.
Just goes downhill from there,because we all have different styles and methods of testing.I've got a CB tackdriver 700V 6mm that doesn't like 4198....on the heavy rest.Does better off Bud's bags.
30-06 = 4895 here.These are sporting rifles with big loads and need the softer pulse to manage recoil.
