Shooting into duct seal

[jim 44-40]

Does shooting into duct seal tell me anything about a bullets performance? 44 mag with 210 gr JHC221803221804[/AT[ATTACH=CONFIG]221804 @ 1600 fps

Tells you if the bullet opens in Duct Seal. Put the bullet where it needs to go and don't worry about it.

[JimB..]

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

[smilie=1: 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!


:roll:

^^^:2_high5:^^^ Sorry I don't have any thing but a smart mouth answer, but it looks like you got good expansion.

I forgot it was duct deer I shot into221814

[jim 44-40]

I know it is a small rack,but it was my first deer I shot when I got out of the Army in 78

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?

[jim 44-40]

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

[bedbugbilly]

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

[MUSTANG]

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

[bangerjim]

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!

Go south and shoot a hog for the best comparison with a human.

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.

[Mal Paso]

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.

[Lloyd Smale]

ill try anything. im flexsealable

[Bookworm]

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.

The Sierra 170gr JHC .41 bullet has been called tough, I put one through a small deer at the diaphragm. Didn't blow a big exit hole, but it didn't expand and stop in whatever amount of fluids it met. 14.5gr of 800x gets that bullet 1550-1600fps in handguns with 6.5-7" barrels, I did not check the load in the 10" T/C Contender barrel I used for that deer, but it had to be moving pretty quick. I also shot a somewhat larger doe with that bullet, but the angle from my tree stand was steeper than I allowed and she ran off a short distance and laid down. I had to creep up and shoot her in the neck to finish that one. The original shot raked the ribs low behind her foreleg, I don't think any bullet would have been a good killer with that shot. If the light .44 version of that bullet is constructed similarly I'd use it.


I've used .41's from Sierra, Speer and Hornady on deer, will carry cast until I get another chance with a handgun.

I’ve seen duct tape used on vehicles dented fenders. Maybe duct seal could be used to patch boolit holes in cars. Ar! Ar! Ar!

[Mac118]

I wasn't familiar with duct seal so I had to look it up. At the retail prices I saw ($24/lb) it seems pricey to make decent size block. Maybe an HVAC supply house for a bulk price?

Bigger than the rack on my first deer, Jim44-40

Great advice, Fred. I've used our swimming pool over the years (when my wife isn't home) to test various bullets in an 'equal' medium. Rod

I think doing it when the wife isn't present shows good common sense and a lot of discretion........:D

If it doesn't deform in duct seal, it won't in water or deer. The bullets seem to be more supported in duct seal than in other media- the weight retention might be better then in reality.

I like duct seal for the first impression of handgun rounds up to 44 Mag.


Never shot a rifle into it, bunt want to give it a try. Any experiences?

One of the advantages of duct seal was the bullets wound channel didn't close up it was visible and retained it shape. Wet newsprint had this to an extent also. Water nd gels close up quickly and may re seal to the point the wound channel is hard to see. Suposedly duct seal wasn't as tmp sensitive as gels were also for good results also.

Gallery Load testing with the 30-06. Left was at 1066 fps, the one on the right 381 fps. I'm shure in wet paper they would have looked the same...
