    Was thinking about 80 grains of BP behind a 71 cal 550gr round ball down a smooth bore. Would this be ok for hunting?

    I have fired .715 patched round balls in my 12 SxS shotguns. I did not attempt a shot at deer beyond 50 yards due to decreasing accuracy. The load would surely be adequate for deer if they were hit in a vital spot. I used 85 gr. of 2F.

    I don't understand the "209 muzzleloading adapter" part. The ignition system should make no difference if you are using real black powder.

    There's at least 2 makers of 209 primer adapters, Pedersoli and Mag-Spark.

    1. https://www.cabelas.com/product/Dav...ple-Conversion-Kit/1608590.uts#tabsCollection

    2. https://warrencustomoutdoor.com/mag-spark.html

    There's some common reasons mentioned by users of both.

    One is personal safety due to the adapter system being enclosed, it can prevent cap fragments from striking a person, especially if they're not wearing safety glasses while hunting.
    I've heard of people being injured by cap fragments so can sympathize with their concern.

    Another reason mentioned is that they hunt in the Everglades which I take to mean that they hunt in wet weather or a wet environment.
    It helps to promote more certain ignition despite the elements, with less chance of a hang fire or misfire which some people may experience whether they're using a substitute powder or not.
    Sometimes hang fires can be caused by dirty barrels or even as a result of swabbing [black] powder fouling into the breech.
    It could be considered to be an ounce of prevention for when trying to make a critical shot.

    Another reason that I've read about and have seen happen to others is that a regular [musket] nipple can expel enough hot gases to actually burn or char the wood and finish of a gun stock.
    By containing the hot gas, blow back damage to the gun stock can be prevented.

    There's other reasons including the use of substitute powders or simply to have an alternative ignition system as a back up.
    It's not always about whether a person needs an item for shooting their muzzle loader with black powder, but whether someone has another preference that they want to try out for any number of reasons.
    Just trying to help shed some light on the subject to help promote a better understanding of some other reasons why people might choose to use a 209 primer adaptor.

    Well it doesn't make sense, but you need to check with your local DNR to see if the state allows such an adapter. Now one of the inlines on the market from H&R used such an arrangement, then went to a screw in plug, so as I said, it should be OK.

    You could use a slug. You should NOT be using any sort of choke, so what you are looking for is either an old school slug barrel or "police" barrel which would be cylinder bore, and rifle type sights would be handy. IF what you are using is difficult to fit with an old style slug barrel then you might find a used barrel that at a reasonable price with a vented rib, and have it cut back about 4 inches to remove the choke. Then you can mount sights on the rib. The directions against slugs are pretty much to cover the maker in case you shoot stuff through a choked barrel. After all you could be where they use buckshot, and they have not idea how many pellets you'd use, so it's not a "weight" problem.

    Lyman makes slug molds for these:

    Lee makes the "drive key" slug

    But the 12 gauge round ball has plenty of umph, and has killed a lot of deer. If you keep the shots in at 50 yards, you should have no worries. OH a .710 ball is 539 grains of pure lead, and 519 grains if you use wheel weights or bullet alloy, give or take a few grains. The deer won't know the difference.

    It's worth noting that when using those chamber adapters, the powder charge may not always fill the entire chamber which can allow some of the shot charge to also fall into the shot shell adapter chamber which may be below where the bore starts.
    If loading a round ball, I don't know if it would be seated on top of the powder charge or not because I don't know its powder capacity or internal diameter.
    Maybe it does or maybe it doesn't.
    That may be another reason why it's not recommended to use it with rounds balls or slugs.

    A load of shot may be able to be seated on top of the powder charge below the bore line in the chamber, but I don't know about a slug or ball.

    If you buy one then perhaps you will be able to figure out how much powder it holds and whether the ball is being rammed past the bore and into the shot shell chamber or not.

    I'm pretty sure that Florida does not allow any gun that can be loaded from the breech to be used during muzzleloading season.

    I use a Mag-spark in a Hawken because I shoot BH 209 powder in it. A 209 primer is necessary to ignite it. I fail to see an advantage for an insertable adapter in a break-open shotgun.

    Just don't follow Canterbury's loading instructions which call for priming first....then loading from the front. Another article in Backwoodsman which I had to call out for safety violations. You never "cap" or prime a ml before loading the powder/wads/shot/ball/etc. At least not if you value your hands, face, life.
