Understanding Tungsten Shot

Its benefits come from the fact that it is denser than any other shot material, including lead, steel or bismuth. To understand how the density factors into performance, let’s look at two spheres about the same size, a golf ball and a ping-pong ball. The golf ball is far denser and will fly farther and hit harder. Now reduce that size down to two single No. 4 pellets, one steel and the other a tungsten alloy. Get the picture? The tungsten will fly farther, hit harder and penetrate deeper. That means more birds, farther out, with fewer cripples.

The beauty of tungsten is you also can reduce shot size and retain all the benefits of the larger lead or steel, with a lot more shot in the pattern. If you normally use No. 4 shot, switch to No. 6 in a tungsten load for a bigger pattern, more range and more forgiveness.

A few years ago, I decided to see just how good this stuff was. I took a mallard I killed that morning, tacked it up over a Shoot-N-See target and shot at it with a tungsten load at 70 yards. Every pellet totally penetrated the duck and left a mark on the target. Neither steel nor lead gave me that result — not even close.

Today, all shotshell manufacturers offer tungsten-alloy loads. The original, Hevi-Shot, is irregularly shaped and mixed in size, yet patterns better than it has any right to. Winchester, Federal, Remington and Kent offer tungsten-based loads that are more uniform in size and, like the Hevi, pattern very well.

Choosing the Correct Choke for Tungsten

We can manhandle lead and, to a lesser degree, steel, by simply forcing it through varying choke restrictions until we get it to behave the way we want it to. Not so with tungsten. Tungsten has a mind of its own and doesn’t play by the rules when it comes to choke.

For most tungsten loads I’ve tested (and I’ve put a small fortune into the pattern board), a modified choke delivers the overall best results in most guns, including over/unders and semi-autos. There have been rare instances where a full choke showed some improvement over a modified — one 12-gauge Spartan o/u and one Franchi semi-auto — but I attribute that to barrel quirks. We don’t know why it’s so, but the densest, most uniform patterns with tungsten most commonly come from modified or improved modified chokes. My tungsten guns always are choked that way.

Can you shoot tungsten in a normal barrel?

Tungsten is definitely harder than steel, and as such, there have been a flood of warnings about not shooting it in ultra-high-end guns or through standard chokes. It will leave marks in a choke tube, but as of yet, I’ve not seen any adverse effects in a barrel.

I wasn’t aware of the concern when I first began testing the then-new Hevi-Shot, and ultimately marred some tubes, but, and this is curious, those marred tubes don’t diminish the patterns in any way, even when I go back to lead or steel shot. My guns are tools, not works of art, so a bit of streaking or scratching in the tube doesn’t bother me. If you have concerns, just switch to a hardened choke tube made for tungsten or steel.
