Keep It in Balance

Keep It in Balance
For sub-gauge shooters using light guns, heavy loads are OK for most upland pursuits, but they are "out of balance" for high-volume shooting.

A huge counterproductive trend in factory shotshells has been the history of developing ever-heavier shot charges and velocities in a given gauge and shell length. For example, it didn’t take long before the 20-gauge 2¾" shell was lengthened to 3" by US manufacturers, to better protect and propel 11⁄8-oz lead shot charges. That was a good move! But this soon was followed by butchering this nice “magnum” loading by throwing out vital shot-charge protection and jacking up load weight to 1¼ oz. The result: an out-of-balance, poor-patterning, heavy-recoiling shoulder buster (for older shooters especially).

In today’s shotgunning world there is an ever-increasing trend of shooting 28 gauge for sporting clays and skeet. And in hunting, 1-oz 28-gauge loads are now abundantly available and have contributed to an increase in the 28 gauge being used for upland hunting. But, judging from correspondence I’ve received, many 28-gauge shooters are starting to get carried away—or confused, as the case may be—as to what 28-gauge loads they should be shooting.

I am speaking specifically about questions regarding shooting 1-oz 28-gauge loads in 12-gauge shooting events or, where there are no restrictions on shot-charge weight, shooting 1-oz 28-gauge loads in 28-gauge events. The reasoning: “Wouldn’t a 1-oz shot charge help break more targets?” My answer is that the 1-oz load likely would pick up a couple more targets per round of 25, especially at longer distances, but only in any bore larger than 28. This is because, first, cramming 1 oz of lead shot into a 2¾" 28-gauge shell is basically the same sin as cramming 11⁄8 oz in a 2¾" 20 or 1¼ oz in a 3" 20. It simply takes more room than is available in a 2¾" 28-gauge hull to allow the wad column necessary to protect the pellets.

You will never shoot well with an out-of-balance, too-heavy load for the gun you’re carrying.

But what is of greater concern is the negative consequences of firing such loads in the typical fixed-breech over/under or side-by-side 28 for multiple shots. I’m speaking of the fact that, as the 28-gauge evolved, the idea was that light shot charges of ¾ oz or less would be shot in light guns carried over hill and dale for bird hunting. Thus were born 28-gauge shotguns commonly weighing less than 7 pounds. Even with today’s 1-oz 28-gauge loads, if all you’re doing is firing a couple of rounds during, say, a ruffed grouse or pheasant hunt, they can be shot comfortably in a less-than-7-pound gun. But what if you’re shooting this gun for doves, skeet or sporting clays, where 25 to 50-plus shells are commonly fired in a day? That is quite another matter. The cumulative recoil generated by such relatively heavy loads in a lighter gun becomes a big minus and begins to contribute to lifelong problems with flinching. In short, you are shooting an out-of-balance load, given the very light gun involved.

Let’s look at the recoil realities. As a benchmark, the typical 11⁄8-oz 1,200-fps load fired in an 8-pound trap gun generates approximately 21 foot-pounds of recoil. But trap shooters quickly learn to shoot such loads in guns approaching 9 pounds. This gets the recoil down closer to 17 foot-pounds. Bottom line: Typical target shooters weighing up to about 200 pounds cannot long tolerate shooting gun/load combinations generating 21 foot-pounds of recoil without at least going to 8-plus-pound gas-operated autoloaders.

For the sub-gauge shooter, a ¾-oz, 1,200-fps load in a 6½-pound gun generates a quite-comfortable recoil of about 11.5 foot-pounds. But increase the shot-charge weight to 1 oz, and now that 6½-pound gun will be transferring about 21 foot-pounds—the same experienced by our recoil-suffering trap shooter above. If you’re going to shoot a lot of 1-oz shells, then, regardless of gauge, you’re going to need a shotgun approaching 8 pounds to get the recoil down to around 16 foot-pounds. When it comes to 28- and 20-gauge shotguns, I shoot an O/U no lighter than 7¼ pounds for hunting with up to 7⁄8-oz and occasionally 1-oz loads and a gun no lighter than 7¾ pounds for target shooting with ¾-oz loads or for hunting with up to 11⁄8-oz loads. Both keep the recoil in the range that I can comfortably handle all day.

It’s a fact that you will never shoot well with an out-of-balance, too-heavy load for the gun you’re carrying. Best results always seem to come from shooting the lightest load that will get the job done relative to your gun’s weight.

    Explain how you cannot get a wad column to protect the shot in a 1-oz. 28-gauge shell. B&P’s wad goes all the way up to the crimp. I have killed many a pheasant with a 1-oz. Winchester 28-gauge. Maybe they didn’t know they were not supposed to die.
