A real eye opener on the differences in shot types and sizes.

6 posts in this topic

I have seen guys on Duck Hunting Chat and Gobbler Nation Forums show the different ballistics with the different shot sizes and different shot densities.

It is a real mind blower to see just how much difference there is between the ballistics in steel shot, lead shot, 12g/cc shot 15g/cc shot and 18g/cc TSS shot.

I just bought the KPY Shotshell Ballistics Program and it is pretty cool to play with entering different shot sizes, types, speeds and the amount of gel penetration wanted.

The KPY Shotshell Ballistics say you need 1.5" of gel penetration to kill ducks and 2.5" of gel penetration to kill geese at a minimum of 600 fps with steel shot.

My guess is you would want at least 3.50" of gel penetration to reliably kill coyotes.

Look at the shot type and the speed of the shot. The amount of gel penetration is on the far right. The target distance is how far away you will get the gel penetration that you enter into the program.

The rows that I wrote Led on are lead shot, RHD is Remington Wingmaster HD shot that is 12g/cc, TSS is Tungsten Super Shot that is 18g/cc.

The TSS "Tungsten Super Shot" is unreal! It is really heavy for it's size and it is very hard so it doesn't slow down much and it penetrates like crazy. TSS is very expensive but many hunters are using it for turkey hunting and in 410s and 28 gauges for ducks and geese.


Look at the steel shot at 1500 fps it doesn't penetrate worth a darn compared to lead shot that is going 1300 fps. Make sure you look at target distance.

I have always wondered why no ammo manufacturers made any lead BBB shot or T shot loads. Look at the difference in target distance between the lead BB, BBB and T shot loads.

Look at the TSS #9 shot and the lead #5 shot and the target distances. I lowered the gel penetration to 1.5" so it would be more like shooting a turkey in the head. Check out the difference in TSS #9 shot and lead #9 shot.
I have shot a few coyotes with TSS #4 shot and it is unbelievable!

Thanks for the info . When I used to den hunt coyotes with dogs it was all shotgun work and our load of choice was copper plated BB 3". Then #4 buckshot was second choice. I might revisit the shotgun as this new dog gets up to speed . He's not of the mindset to be a decoy ,he's going to be a den crasher / blood trailer . I might even invest in a new shotgun ,as I traded my Benelli for a 700 Remington lvsf223 a few years ago.

I did some patterning today with my Benelli pump and a 24" barrel.

shot size was #4 buckshot, copper BB, and dead coyote t shot

chokes ranged from a tight dead dog primos .670, full, mod, impr.

ranged distance , 42 yards and 60 

the # 4 buckshot shot the best with modified choke. The tighter choke created an open hole in the middle pattern

Bb also did ok with the modified , tighter chokes not good. 

Dead coyote did very good with the tightest choke ,a great pattern

in the 60 yard range the BB and # 4 was dismal, as it was a real roll of the dice,however the dead coyote load with the tight choke produced a consistent 6 pellets in an 6" circle. Plenty to kill a coyote. 

Summary, my first choice is the t shot in my gun ,with a toss up between the other two . Those patterns were not great. And limit your shots to 40 yds. Which load has better knock down I don't know. Hopefully Dabob will chine in . Eric

I got some 3-1/2" heavy shot" b", 1-3/4 oz shot . I patterned it at 60 yards and it's a heck of a load. According to the sheet Bob it should be a good load.
