I had one heck of a time hitting anything last year, and I consider myself a fair shot. And on my final day of hunting last year it took half a box of shells to get 1 duck - and I had to shoot that one twice. After hunting season ended, I did a pattern test and found that my gun’s pattern was really bad. My gunsmith identified a bulge in the barrel that I hadn’t noticed, right about where my built-in choke started.

Above: pattern of shot at about 20 yards with my 12ga. having a bulged barrel.

Overview
I attribute the bulge to the steel shot I was using, and even though my gun isn’t a vintage or antique - I believe that dad bought it for me around 1976 - it couldn’t handle steel shot. I also experienced problems adapting to steel shot a few years ago when I resumed bird hunting after about a 12 year hiatus. Steel shot doesn’t have the penetrating power as lead, due to the lighter weight of steel shot the range is greatly reduced and the pattern is not as compact, and one needs to adapt to larger shot size for the same effect.
More and more hunting areas require non-toxic shot. If you have older guns that you like to hunt with, the choice is either to use non-toxic alloys, or steel shot that can ruin a gun as it did mine.
After doing a little research, I selected HEVI*SHOT® Classic Doubles for vintage guns. Manufactured by Environ Metal the shot is made of Iron, Nickel, Tungsten, and two additional alloys. I received a box each of 16 gauge 4 and 6 shot, 1 oz. loads, 2 ¾ inch shells. These shells are non-toxic and designed to use in older and vintage shotguns; I tested them on a Sears & Roebuck Ranger shotgun manufactured by Harrington Richardson between 1912 and 1932.
Criteria and Review
Criteria 1-4 are from a Cabela’s web site advertisement. Criteria 5-7 are from information found on the boxes of HEVI*SHOT® shells.
Criteria 1- A safe, nontoxic alternative for older shotguns, this low-pressure, low-recoil ammo has 44% more energy than comparable steel loads, yet it’s as soft as lead for the protection of barrels and fixed chokes. HEVI*SHOT® was not compared to steel shot due to the age of the gun in which it was tested, but it was compared to lead shot. The gun on which it was tested contains a fixed choke. A casual observation of the wood on which the targets were placed, appeared to have about the same number of HEVI*SHOT® imbedded in the wood as the lead shot, indicating that it has about the same penetrating power as lead.
Criteria 2- Buffered loads and sealed hulls ensure optimum all-weather performance.
The hulls are sealed in the same manner as older shells that I have been shooting. Some shells that I still use are over 30 years old, have been used in all types of weather, and have not been properly cared for (ie. left in hunting vests, vehicles, etc.), yet they still perform as new.
Criteria 3- For use in any firearm that can safely fire modern lead trap loads. The shells normally used in my shotgun are high power 2 ¾ inch, containing 4, 5, 6 and 8-shot.
Criteria 4 -The shells are loaded for the specific needs of waterfowl hunts. Lead shot is banned in hunting waterfowl as well as many hunting reserves and wildlife management areas. The non-toxic shot used in HEVI*SHOT® shells are similar to shooting lead shot, and from experience, is much more effective than steel shot. In older guns such as my 16ga. steel shot is simply not an option.
Criteria 5- This ammunition maintains down range energy, resists cross-wind effects and delivers devastating lethality. The pattern tests of both lead and HEVI*SHOT® were conducted in a 20-plus mph tail wind at 40 yards. Both lead and HEVI*SHOT® shells used were 2 ¾ inch, 4-shot. The wind conditions are attributed to elevating the lead shot, while it appeared to have little if any effect on HEVI*SHOT®.

Above: pattern of shot at about 40 yards in a 20mph tail wind with my 16ga. using 4-shot lead.

Above: pattern of shot at about 40 yards in a 20mph tail wind with my 16ga. using 4-shot HEVI*SHOT®.
The HEVI*SHOT® resulted in approximately 81 bb’s within the target area (the wind tore out a small section of the target containing several holes). That same area for lead shot resulted in 62 bb’s.
Weight and velocity are the greatest factors in lethality. I did not conduct specific gravity tests on HEVI*SHOT®, lead or steel shot but as a general comparison, Steel has the specific gravity of 7.8; lead has a specific gravity of 11.35; each of the alloys used in HEVI*SHOT® have specific gravities of: (cast) iron, 7.85; nickel, 8.9; and tungsten, 19.
Criteria 6-HEVI*SHOT® shells create a remarkably tighter pattern and group. Compared to lead, the HEVI*SHOT® produced a tighter pattern when tested in an approximate 20mph tail wind. HEVI*SHOT® was not compared to steel shot since it was tested on a vintage gun and experience with my 12ga. made it clear that steel shot could not be used in the vintage 16ga.
Criteria 7- This uniform pattern and group allows fewer misses and less crippling.
The uniform pattern does allow fewer misses and less crippling since the tighter pattern puts more shot in a smaller area, but the biggest part of the equation is your shooting style. The shot won’t improve your shooting if you are a bad shot or take chances, but will certainly improve your chances for a kill if you hit what you shoot at.
Disclaimer and Safety Information
There is always some risk in shooting older and vintage guns due to the wear and tear over the years, how well the gun was maintained, and the quality of manufacture. Before shooting vintage guns, it is always a good idea to have them checked out by a reputable gunsmith.
Summary
In summary, I recommend the HEVI*SHOT® shotgun shells not only for older and vintage guns but wherever nontoxic shot is required. The shells average in the neighborhood of $2.30-$2.60 each but knocking down your birds with fewer misses and wounds may make them more cost-effective; with steel shot I oftentimes had to shoot ducks twice or 3 times, which I resented having to do since I make every attempt to make my first shot a kill.
Response from Environ Metal
The pattern shot looks like it was high on impact- nice review- Non-tox and steel are in same category– and non tox is required on all waterfowl nationwide! Nice review!
