Load #4
10 Gauge
Hull: Remington 3.5” (Low Base, the newer design)
Primer : Remington 209p
Powder: 38.5grs. SR 4756
Wad Column: BPD-10 (molly or HBN coated with three petals split 2/3 the length of the wad) – (3) 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.
Shot: 58 pellets lead T-buck
Crimp: Roll crimp with Ballistic products 12ga. frangible plastic over shot disk and seal the edges with a soft silicone (a small syringe works well for this).
Velocity: 1390fps
Pressure: 10.9KPSI
Notes: This load works well in auto loaders and is very temperature stable. This hull/powder/wad combination is reliable in my BP-10 to near zero degrees F. For my gun, this load patterns best with a Browning or Briley Full or X-Full choke.
