I now prefer Magnum to any powder used previously.

Ruger #1 with 26-inch barrel. Win. cases, 215 primers, 3.50" overall length.

180 TSX - 86 gn for about 3100 fps.
200 AccuBond - 83 gn for 3000 fps.
200 Partition - 82 gn for 3000.

Reducing the OL to 3.34" reduces the velocity by about 50 fps. The accuracy of the 180 TXS seems unaffected. Groups with the 200 gn bullets opened up to around 1.25" at 100 yd.

Cheers
