Choosing Shot Size
Spring gobbler hunters always seem to be tweaking something, whether it’s their various call lineup, to camo patterns and, especially, shotgun loads to deliver the best pattern possible when the moment of truth arrives.
In recent years technology has taken shotgun loads and choke tubes to the next level, and longbeard chasers have literally bought into it and outfitted their shotguns with shotgun shell and choke tube combos that send a swarm of shot downrange toward an unsuspecting gobbler.
It’s gotten to the point where you wonder what will be next.
Well, wonder no more.
There’s a hardcore fraternity of turkey hunters and reloaders who have taken that next step, hand-loading TSS – Tungsten Super Shot – shotgun shells with incredible results. I’ll stop short of talking about the extended range these loads offer because I’m an old-school – maybe just plain old – turkey hunter who feels it’s a 40-yard game, or should be.
But the patterns and power these loads deliver is nothing short or amazing.
There’s a reason. TSS is the heaviest shot available today, weighing about 18 g/cc. Its hardness requires shotgunners to take extra precautions to ensure it doesn’t damage your gun or choke tube. But if loaded properly, there’s no problem.
Hand-loaders and turkey hunters are reporting devastating patterns to 40 yards and, if you insist, well beyond – even from 20 gauges and .410s. Because of its weight, you can use small shot sizes – 9 shot is commonly used – and send a deadly swarm of pellets downrange into that 10-inch circle gobbler getters typically use to gauge their pattern’s effectiveness.
That’s the good news. The bad news it’s expensive; most estimates from hunters who are loading TSS say over $7 a shell. At that price and given the relatively small market target, it’s highly unlikely you’ll see it on any shelves anytime soon.
Too, it could accurately be described as overkill. Let’s be honest: lead shotgun loads will kill turkeys. And with the variety of Hevi-Shot and other specialized turkey loads available, there are plenty of excellent options available on the market today.
But for the guy who wants to kick it up a notch, TSS has a core group of followers.
It’s all part of the advance in technology today, in turkey hunting and virtually everything in society. You don’t have to embrace it all, but it’s available. And some spring gobbler hunters who load their own shells are now dedicated followers of TSS.
A question that always comes up with TSS, is what shot size to use.
Given that the whole reason TSS is so much better is due to the high density of the pellet material - which enables one to go down in shot size in order to increase pellet count and pattern density, without losing any individual pellet penetration energy or to actually increase that penetration energy - the question of optimal pellet size of how far down in size to go, is a good one to consider.
The good news is, with the available ballistics software, it's easy to come up with what the optimum pellet size for a given situation is. Here's how I look at it - using turkeys as the game for illustration purposes.
You have basically two things to think about - pellet penetration and pattern density. You need both to kill turkeys consistently and cleanly. And there is a trade-off of those two things with each shot size and payload. For pattern density, I have a minimum standard of 100 in a 10" circle. For pellet penetration - 1.25" in ballistics gelatin. (These standards will be obviously different for other game birds and waterfowl.) Both these minimum standards must be met in order to know you will have a dead turkey 100% of the time you put the core of the pattern on him, at whatever range within those limits. The ideal shot size is the one where you max out on both those minimums at about the same time. Then you aren't dealing in overkill on one, at the expense of the other - since a shortage of either will hurt you. That's why I generally prefer smaller shot sizes in the smaller bores, and larger in the larger bores - to match up the pattern density and pellet penetration - thereby maximizing the efficiency of your rig and ammo.
For illustration, let's say I have a 1-5/8 oz 20 ga load that goes 1150 fps MV. What's the optimum pellet size?
With number 8s, I know I can get 220 in a 10" circle at 40 yds. Using the .7 rule, that means I can get 100 in a 10" circle out to a little over 60 yds. And the 8s give 1.25" penetration out to 92 yds. So, I have a gap between the pellet penetration and the pattern viability of about 30 yds.
With number 8-1/2s, I know I can get 270 in a 10" circle at 40 yds. Using the .7 rule, that means I can get 100 in a 10" circle out to almost 70 yds. And the 8-1/2s give 1.25" penetration out to 82 yds. So, I have a gap between the pellet penetration and the pattern viability of about 15 yds. We're getting closer to the optimal size for the 20 ga.
With number 9s, I can get 310 in a 10" at 40 yds, so the numbers are 70+ for the pattern viability, and 72 yds for the pellet penetration energy. Those match up almost perfectly, with no gap between the pattern viability and pellet penetration. So, that's why I choose #9s for the 20 ga, for turkeys.
You can do that same exercise with any pellet size, payload, and game, to figure out the optimal pellet size for what you're trying to do.
