Never really messed with reloader 17 much just threw a load together yesterday 28in shilen select match bull barrel 8 twist lrp build. 44 grains of reloader 17 muzzle velocity 3030 inch and a half group at 400 yards. 44.5 grains 3070 muzzle velocity same group at 400 I love the powder now. But heard it's hard on throats? Thanks for listening just thought I'd throw that out there. Oh edit 6.5 Creedmoor. 130 grain AR hybrid
