    Tells you if the bullet opens in Duct Seal. Put the bullet where it needs to go and don't worry about it.
    To paraphrase Ronald Reagan, the trouble with many shooting experts is not that they're ignorant; its just that they know so much that isn't so.

    I’ve never hunted a duct seal, or any other seal for that matter, but those bullets sure look good.

    Now someone is cross-breading ducks with seals? OMG.............what next!

    Better be careful......the enviro-greenies will declare ductseal an endangered flock/gaggle/hoard/mob/species!

    Over the years numerous mediums have been used to test bullet expansion. I remember when modeling clay was the hot item, then it was water soaked newspapers, water bottles, gel, etc. Some people even test by shooting into logs.

    If you shoot different bullets into the same medium, it will give you an idea of what each bullet will do when it encounters the same resistance, elasticity, hydrostatic effect, etc. Whether that translates to real world performance on a living target is still up for debate, even by the professionals.

    The bottom line is, it's fun to shoot stuff and compare the results, so have at it...!!

    Hope this helps.

    That's interesting, how deep did it penetrate?
    It did show you that the bullet held together well...did you weigh them after they expanded to see their weight retention?

    At 10 yds it penetrated 4 inches and had no weight loss ,the block of duct seal was a little soft from heat outside, sorry bullet weighed 210gr going in and 200.6 after I removed it

    I certainly hope you got your Federal "Duct Stamp" before you killed any of those Duct Seals.

    Is it mandatory to use Duct Tape to repair holes in Duct Seal?

    I cannot use duct seals of any kind around my place. They all seem to want to live in the swimming pool in the back yard! And the noise.....Noise......NOISE! Of those seals!

    Sorry, I just can’t let this die! HA......ha!

    Bullets which expand in Ductseal may not in game or gelatin. For the redneck poor boy's test medium water jugs are as good as you can get for the money. Penetration in water is about 1.7 times greater than clear gel, but milk jugs are easily accumulated and stacked and if you test a well proven factory load, you have a good benchmark. I figure any load which expands and penetrates 25-30" of water is a "good" load.

    Great Idea! Except we call it Duck Sh** due to the color. I've always had the noses blow off hollow points in water not so in more viscous substances. Wet newspaper was never that much fun.

    I bought a case of duct seal 25 years ago as a medium to test bullets. I still heave the case of duct seal. Thanks for this thread, now I remember why I bought the case of duct seal.

    I've read articles from gun rags of the 60s and 70s, in which Duct Seal is used as a testing medium. I think it was used for a few reasons, mostly because it is reusable.
    It's also relatively inexpensive, at least when compared to one-use ballistic gel.

    Come to think, I'm not certain if ballistic gel was available then.
