At a launch velocity of fps, #2 steel retains fps strike velocity at 40 yards. At a launch velocity of fps, #4 lead (actually a lighter pellet) retains fps strike velocity at 40 yards. The #4 lead pellet is more lethal due to both higher strike velocity and better penetration.
May 04, · The biggest factor is the shooter, not the pellet penetration, choke, pellet size, pattern density, bore size, velocity, etc and on and on. Mark aka Mr. Tactful.
The fps rule-of-thumb gives distances for that are too far for pellet sizes smaller than #3 and too close for the pellets larger than #3. Note also that the velocity required for inches penetration in ballistic gelatin varies greatly for the different diameter shot from fps at the smallest size shown to fps for B shot. -the penetration of”, and” round ball shotgun loads -the effect of increased muzzle velocities on target lead for steel shot (sizes BBB-#6), at 40 yards Below each table the range which the pellets would penetrate ”, ”, and ”, (given the muzzle velocity for the pellets in that table) are listed.
No. 5 lead shot, fired at the same velocity, is dramatically better than steel, giving more penetration at 45 yards than the same size steel pellet can manage at 20 yards. No wonder #5 lead has been a solid pheasant and duck pellet for so long.
