HOW TO SWITCH - SHOTGUN

The Basics:

Wing Shooting
  1. Know what your shotgun can and cannot shoot, i.e. is it a lead only barrel? Is your barrel rifled or smooth? etc…

  2. Pattern your shotgun.

  3. Familiarize yourself with the lead-free alternatives and best applications for each.

Shotgun Patterning

No matter how long you have been shooting, patterning your shotgun is as important as sighting in your rifle.

“Our downright insistence is that everyone pattern their shotguns. It’s true woodcraft, a win for you and a win for the birds, really. Not only do we encourage patterning to understand exactly what you and your shotgun are capable of at a chosen distance, it’s one of many intelligent ways to lower the staggering number of birds lost to crippling each year.”

— Lee Kjos, SLF Advisory Council Member

 

Step-by-Step Guide to Patterning:

 

STEP 1:

  • Cut paper or cardboard into roughly 48” x 48” targets.

  • In the middle of the target, draw a large dot to aim at.

  • This gives you enough room to see your pattern even if your point-of-aim is off a bit. If it’s off, it’s no big deal. It’s normal.

 
 

STEP 2:

  • Start at 30 yards. It’s a good starting point.

  • Shoot off-hand, NOT on a bench. Nobody shoots game off a bench.

  • Shoot the target.

  • Shoot another target at 40 yards or whatever distance fits your style of hunting.

STEP 3:

  • Draw a 30” circle around the densest part of the pattern and mark the hits with a marker. Now do the math (we promise you can do it).

  • Divide the number of pellets in the shell (check with your manufacturer if it’s not listed on the box) by the total number of hits in the 30” circle.

  • Move the decimal point two places and that’s your percentage of pellets in the “kill zone”.

  • This will change as you try your different chokes at different distances.

 

Shotgun Pellet Alternatives

Many hunters have been skeptical about the effectiveness of lead-free shot for hunting/shooting purposes and compliance, when measured, is often poor. However, where field trials comparing lead and steel shot have been conducted, no differences were found in a number of measures, including the number of birds killed per shot or wounded per shot (Pierce et al., 2014). 

All shotguns can shoot lead-free alternatives to lead, but certain shotguns can only shoot certain alternatives, and it’s important to know which works with your firearm. Shotguns with a “lead only” barrel CANNOT shoot steel shot loads. They can, however, shoot bismuth and copper-plated bismuth. So, if your grandparent gifted you their vintage “lead only” shotgun you can still hunt lead-free! If you are ever unsure about the safety of lead-free ammunition in a particular shotgun, contact the manufacturer or a gunsmith. We’ll go through each lead-free alternative and any necessary adjustments when switching.

  • STEEL

    Steel is less dense than lead, so to use it most effectively you need to go up by at least two shot sizes. For example, if you would use a lead #5 for shooting ducks, you should use a steel #3. Current guidance when using standard steel shot is to shoot no tighter than half choke. Using tighter than half choke risks damaging the barrel. Modified and Improved Cylinder chokes are the most recommended choke constrictions when hunting upland game with lead-free ammunition.

    Most shotgun shell manufacturers have a steel shotshell line.

  • BISMUTH/COPPER-PLATED BISMUTH

    Bismuth is as soft as lead, but 86% as dense, so it is advised that you increase your shot size by at least one. Due to its softness, bismuth tends to pattern much the same as lead and therefore no action is needed when choosing choke constrictions.

    Manufacturers of bismuth shotshells include: Boss Shotshells, HEVI-Shot, Kent, Browning, Federal Premium, Fiocchi, and Rio.

    ATTENTION: Many manufacturers now make copper-plated lead. These are NOT lead-free!

  • TUNGSTEN

    Tungsten is more dense than lead, because of this, loads can be smaller than lead shot. Please check your state’s turkey hunting regulations for minimum and maximum shot size restrictions. Tungsten is often more expensive than lead, steel, and bismuth ammunition. Tungsten is a great alternative for turkey, predator, and pig hunters because these game animals often offer limited shooting opportunities, making the price a little easier to swallow compared to using tungsten for upland or waterfowl hunting.

    Manufacturers of tungsten shotshells include: Boss Shotshells, HEVI-Shot, Kent, Federal Premium, Rio, Fiocchi, Apex Ammunition, Salt Creek Ammo.

Wounded Birds

It is estimated that between 1020% of gamebirds are wounded and unretrieved and can have embedded lead pellets in their body.

Wounded birds become easier prey for eagles and other raptors. As a raptor consumes their prey, they can unintentionally eat the lead embedded in the wounded gamebird.


Grit Pickers

Many birds use grit to aid in digestion. Grit can be stones, sand, gravel, pebbles, and unfortunately, spent lead shot.

One study determined that 1,900–2,400 metric tons of lead shot is potentially deposited across North America annually from dove hunting alone (Haig et al. 2014).

Birds that ingest lead become weakened and are the first to get picked off by hawks, eagles, and owls.

Raptors can easily consume the entire lead-filled gamebird gizzard.

WHY MAKE THE SWITCH?

Slugs

Generally, for slugs and shotguns, either the barrel needs rifling, or the slug needs rifling. Sabot slugs (pronounced “say-bo”) are best for rifled barrels, and there are plenty of lead-free copper sabot slug options. Although it’s possible, the options are limited with slugs for smoothbore barrels (where the slug should be rifled). Slugs for smoothbore barrels are called “Full Bore slugs”, or “Rifled slugs”. Rifled slugs can be broken down further into “Brenneke” and “Foster” slugs with the difference being that Brenneke has a finned tailpiece and Foster does not. Pump action shotguns are a very popular firearm for slug shooting, and a scope could be added too.

Benefits to Lead-Free Copper Sabot Slugs:

  1. More aerodynamic and accurate

  2. Flatter trajectory with better range

  3. Better expansion and weight retention

HOW TO SWITCH:

Many major manufacturers have copper, polymer-tipped sabot shotgun slugs on the market. These slugs easily outperform traditional lead rifled/foster slugs. Compared to lead sabot slugs, they are just as effective, but with better expansion and weight retention. Remington Accutips are arguably the most popular lead (bonded) sabot slugs on the market. However, there are many premium copper sabot slugs options that are cheaper. There are also sabot slug specific rifles too (e.g. Savage 212/220). Compared to rifled barrel shotguns, these rifles perform much better, with faster twist rates for greater accuracy and range. 

Lead-free options are limited for rifled/foster slugs for smoothbore shotguns. However, there are some lead-free slugs where the manufacturer states that they work for both smoothbore and rifled barrels (see below). If you can change out the barrel of your shotgun, you could buy a compatible rifled barrel to use copper sabot slugs.

A few last things, shooting sabot slugs with a smoothbore barrel will not be very accurate. Imagine throwing a football without a spiral! In terms of smoothbore barrel constrictions, it is highly recommended to shoot slugs though a cylinder or improved cylinder choke, anything tighter can create safety issues.
