By no means do I claim to be an expert but here's the results I got Monday. Rifle: 1874 Shiloh Sharps, Badger Barrel, 40-65 Winchester chamber, short leade. Brass: Reformed WCC 67 45-70 fully fireformed, annealed and trimmed, etc. Load: 65.2 +/- 0.1 gr Goex Olde Eynsford FF(g) drop tubed, 0.019 card wad, compressed 0.520 below case mouth. Bullet: 420 gr Paul Jones 40001 with half thickness first driving band, cast 30:1. Lube: Emmerts. Bullet was seated against the wad to set the case mouth mid way down the second driving band, leaving the second driving band about 0.050 off the lands. 10 shots were fired with slip fitted bullets, one fouler, wiped with RV antifreeze mix, at one of the ASSRA 200 yard iron sight targets at 200 meters. The barrel was cleaned, the sights lowered 3 minutes to separate the groups, another 10 shots at the same target except these had been neck sized then expanded with a 409-411 plug and seated with the seating die set to just straighten the slight flare in the case mouth. Again, one fouler, then an RV antifreeze wipe between shots. All shots prone off crossed sticks, iron sights. Without neck tension the group was about 8 inches, with neck tension about 2 inches. Certainly not all that impressive for a schuetzen match but I was trying out my new powder and the theory that slip fit bullets might be more accurate in my BPCR rifle. They weren't. Your mileage will vary.
