• Length: 1.290 inches
• Cavity depth: 0.550 inches
• Cavity diameter: 0.429 inches
• Weight: 60 grains

The 20 Gauge SPW can be loaded with a pure lead .44 caliber factory bullet or one of your own casting.
Bullets that are jacketed or coated will not be effective due to their inability to set back in the splines for grip to get the full rotational spin.

  • Lead Hammerhead cast slug:        350 grains
  • SPW weight:                               60 grains
  • Total Projectile Weight:                410 grains
  • Expansion                                   1.10 inch or better
  • Weight Retention                         100%


 

Sabot Pressure Wad Specifications - 12 Gauge

  • Outside Dia.:         0.727 cal. solid wall sabot w/double chevrons
  • Total Length:         1.55 inches
  • Cavity Depth:        0.620 inches
  • Cavity Dia:            0.50 inches
  • Weight:                 77 grains

 The 12 Gauge SPW can be loaded with a pure lead .50 caliber factory bullet or one of your own casting.

Bullets that are jacketed or coated will not be effective due to their inability to set back in the splines for grip to get the full rotational spin.

Notes on Loading the SPW

  • SPWs are to be finished with a ROLL CRIMP
  • Best accuracy will be achieved if all loaded shells (of same powder charge) are of equal finished length
  • The nose of the slug must not protrude beyond the roll crimp of the hull.
  • Use straight wall hulls
  • Roll crimp on slow speed
  • Cheddite hulls with 16mm - 25mm brass are recommended and were used in load development.
  • Some muzzle brakes can decrease accuracy

 


Questions & Answers

Q: What do I do if the nose of the slug sticks out beyond my roll crimp?

A: The reason for this occurrence is different powder charges allow for making the sabot set at different heights in the shotgun shell.

  1. Shoot the loaded round in a single shot shotgun.
  2. For pump or automatic guns, load only one loaded round in the chamber and only one in the magazine tube, making it a two shot gun.
