Full disclosure: I am NOT an expert when it comes to shotguns, shotgun ammo, ballistics and the art of wing shooting. I shoot a few rounds of clays every summer and pattern my guns and chokes once in a blue moon. Beyond that, I just take the same guns to the field every year and feed them the best ammo I can afford. So the following review of Kent's new Bismuth cartridges is the opinion of a hunter who just wants his gun to go boom! when he pulls the trigger so that delicious game will end up on his dinner plate... nothing more, nothing less.
A while ago I wrote about my desire to go completely lead free for all my hunting and my journey down the rabbit hole of trying to find lead-free, non-steel ammo for my beloved Darne shotguns. I then updated one of the posts with the following great news: Owners of vintage guns rejoice! ... Kent Cartridge recently announced "the rebirth of an old favorite" by introducing their new Bismuth Premium Shotshells.
Here is a video from Kent Cartridge that explains the development of Bismuth shot shells and the improvements that have been made in the new loads.
Just before the 2017 season opened, I managed to get my hands on a good supply of the new Kent ammo in 12 and 20 gauge loads. Since then, my wife and I have been using it exclusively. We've taken snipe, woodcock, ruffed grouse, sharptailed grouse and a few ducks and geese. My wife even shot a scotch double* ON GEESE with her 20 gauge loaded with #5s! I wrote about that amazing shot and posted some photos here. (*two birds with one shot).
In terms of performance, I could not tell the difference between Bismuth loads and lead loads. Now before you get your bloomers in a bunch and start rattling off newtonian physics equations let me qualify my statement by saying it applies to me, to my guns, in the areas I hunt, on the game I pursue. As with all things related to shotguns and shotgun ammo, your mileage, as they say, may vary.
My hit/miss/crumple/wound ratio was nearly identical this year compared to last. For example, on a trip to North Dakota in 2015, I shot 14 pheasants with 16 shots (lead #5s). All but two dropped stone dead. This year, in the same general area under the same basic conditions and with the same gun I shot 15 roosters with 17 shots (bismuth). All but one crumpled, and that one did not go far. (note: the above stats make me seem like some kind of superhero wing shooter. I am not. I am a terrible trap shooter, useless at skeet and barely on the scoreboard at 5-stand. The reason I bag a decent number of roosters with so few shots is because I am a very patient pheasant hunter with decent dogs. I pass up all birds that are not pointed, all birds beyond about 35 yards and only pull the trigger on birds I am pretty confident I will kill outright.
In terms of actual ballistics, as mentioned above, I can only confirm that the shells did indeed go boom! when I pulled the trigger and that birds did indeed crumple when my aim was true. If you want an expert opinion on the witchcraft of shotgun ballistics as they apply to Kent Bismuth loads look no further than gun guru Randy Wakeman to see what he has to say about them:
As a practical matter, assume that you want a minimum of 1.75 inches of ballistic gelatin penetration for pheasant. This cannot be exact, for gel penetration does not consider feathers, much less breaking bones. It is a comparative simulant for soft tissue only. If you are using #2 steel shot at 1400 fps, you are out of gas at 35 yards. With the lower recoil 1350 fps Kent Bismuth #4 load, you are good past 41 yards. #4 bismuth has better penetration at all ranges than #2 steel. In addition, a 1-1/4 ounce load of #4 bismuth has 24.5% more pellets than 1-1/4 ounces of #2 steel. If you are sick of the poor ballistic performance of steel (why wouldn't you be?) and can afford to pay twice the price for your shotgun shells, the new Kent Bismuth loads just made steel shot obsolete. (full article here).
Kent Bismuth shot sizes are apparently true American sizing and not one size smaller like some other loads from Europe. Kent Bismuth #4s are the same size as any other American #4s. The other maker of bismuth ammo, Rio, apparently uses European shot sizes. So Rio's #4 shot is actually closer to American (and Kent's) #5 shot. Kent shells are clearly marked and seem to be made of high quality materials. Word on the web is that the hulls are Cheddites. UPDATE: Kent now sells their new Bismuth loads in boxes of 25.
Bottom line: I will go one further than Randy Wakeman and say that for me, the new Kent Bismuth loads have made steel AND LEAD shot obsolete.
Furthermore, shooting bismuth shells allows me to focus more on the actual hunt. With a few boxes of #5s and #6s, I can use any gun I own to shoot any gamebird I pursue on private or public land no matter what the regulations are. No more swapping out ammo when going from lead-allowed to non-tox areas, no more sorting through different brands, sizes, and loads trying to get the perfect combination for geese in the morning, snipe in the afternoon and ducks at dusk. I am now lead-free in the field and thanks to Kent, when it comes to ammo, I am also worry-free.
