Load #7
10 Gauge
Hull: Federal 3.5”
Primer : Fed. 209A
Powder: 3.0grs. 700-X And 65.0grs IMR-4227
Wad Column: Precision Reloading TUFW105 (molly or HBN coated pre-split) – (1) 1/4” felt or wool wads in the bottom of the cup
Buffer: Ground polyethylene (Ballistic products SD-C works well - add about 2 grams of molybdenum disulfide to 1 pound of buffer) – add buffer with gentle tapping till all interstitial sites are filled and the buffer is level with the top of the shot column (about 25 grains).
Shot: 40 pellets lead 4-buck
Crimp: Fold crimp with a Precision Reloading tyvek over shot wad on top of shot column. Seal the crimp with soft silicone
Velocity: 1275fps
Pressure: 10.4KPSI
Notes: This load was derived by Tom Roster a couple decades ago. It is a duplex powder charge load and must be loaded such that the 700-X sits directly above the primer and the IMR-4227 sits on top of the IMR-4227. There should be sufficient wad/crimp pressure to hold the powder column in this arrangement. I don’t recommend this load to anyone. The only reason I included it was because it generates some phenomenal patterns. The pressure is also fairly consistent over a wide range of temperatures. It is a fairly dirty burning load.
