It is about time that some guys are buying shells so I figured I would show a comparison between a couple of 3 1/2" loads.
Some people think "speed kills". Others think you need "fast enough" pellets. Here are some differences in a 1 9/16 load of 2s @ 1300 fps and a 1 3/8 ounce load of 3s @ 1550 fps. Both are comparebly loads in most respects.
1 9/16 2s @ 1300 approximately 197 pellets
1 3/8 3s @ 1550 approximately 210 pellets
penetration at 35 yards in ballistic gellatin: Both 1.86"
average energy at 35 yards: 2s- 4.12 ft/lbs 3s- 3.87 ft/lbs
50 yards
penetration 2s-1.40"
3s- 1.37"
energy 2s- 2.76 ft/lbs
3s- 2.48 ft/lbs
-------------------------------------
What about lead? This may blow some peoples mind.
The median speed on a crossing mallard is 70 ft per second. Hence:
20 yards
2s @1300 3.9 ft of lead
3s @ 1550 3.4 ft of lead
30 yards:
2s @1300 6.3 ft of lead
3s @ 1550 5.6 ft of lead
40 yards
2s @ 1300 9.2 ft of lead
3s @ 1550 8.3 ft of lead
50yards
2s @1300 16.3 ft of lead
3s @ 1550 15.0 ft of lead
This is a 90 degree crossing mallard at median speed. As the angle decreases, so does the advantage of speed to decrease the lead needed. I have a feeling the faster load does not decrease the lead required as much as you thought.
-----------------------------------------------------
Lets go to kick.
In a 7.2 lb gun (Super Black Eagle with 26" barrel weight)
the 1 9/16 load at 1300 fps has 54.6 ft lbs of recoil energy
the 1 3/8 ounce load at 1550 has 68.0 ft lbs of recoil energy
--------------------------------------------------------
Patterns
The slower loads are normally going to be easier to get a good pattern with (although guns will differ).
--------------------------------------------------------
My Conclusion
There are so many different setups that will work for different situations. If you just buy a shell and throw it in your gun, it may work okay. If you want the best chance to kill what you shoot at, you need to pattern different loads and remember SPEED DOES NOT KILL when it comes to shotshells. FAST ENOUGH pellets with a pattern density recommended by the CONCEP (Cooperative North American Shotgunning Education Program) is what kills.
