10mm 220gr Hard Cast vs 22 Water Jugs

[@jimseaman2558]

Thank you for taking the time to do this test and video. I have recently purchase the Underwood 10mm 220 hardcast for woods carry. You have saved me some time and expense in the way of testing. Enjoyed the video!

[@boxerwagon]

Just ordered 2 boxes for my fiancees son who is working in Wyoming on a cattle ranch. They have been seeing several grizzles lately. His father got him a Glock 20 and i got him some bear stoppers. Hoping he never has to use them but if he does looks like it will do the job. I have been using Underwood for years out of my Sig Sauer P220 and love it.

[@newtestamentchristianacts2316]

Did he ever have to use them?

[@yellowjacket7134]

I live in Alaska and when I'm hiking, camping, fishing etc my go to is the XDm 10mm loaded with 200 to 220 grain hardcast from Underwood.

[@freedomlover425]

If you ever need to use it I hope it serves you well!

[@yellowjacket7134]

I just hope i will never need to use them..

[@achav012]

So, I’m curious about why you’d go with 200gr over 220gr. I’m having this dilemma right now on what bullets to buy and load for my XDm10.

[@yellowjacket7134]

@@achav012 I will use both. The 220 grain will just give a little bit more recoil due to the heavier weight but both will do a great job. My preferred choice would be the 220 grain hardcast for larger animal protection.

[@boogerdog5247]

@@yellowjacket7134 That is some awesome, I do mean awesome stopping power, penetration. I'm eastern U.S., don't shoot 10mm, but recently purchased Underwood ammo for the 50 Beowulf. 420 extreem penetrators, and some flat nosed. After reading their bullet designs and terminals, I must say, Underwood has to be the best kept secret in the industry! Btw, their customer service is A+, and they go well beyond the norm to accomodate. Currently, they have 10mm IN STOCK. These days, you just about have to buy the ammo, then find the platform to send it. Impressive, (10mm hard cast) doesn't do justice to the description.

[@Bigtrain1]

Enjoyed the video, that's my hiking and protection round when bow hunting in the Rockies. Looks like it works.

[@freedomlover425]

I'd say it does, thanks for watching!

[@wyattblessing7078]

Great video. Seen all your Underwood 10mm videos. A great bunch of ammo and I appreciate your testing.

[@freedomlover425]

Thanks a lot for watching!

[@Alienz117]

I use the same round. It definitely has more recoil than my old brand of 180 grainers! I liked your video!

[@jackmclane1826]

Ah... those keyboard scientists that get a hickup about the shape of jugs^^.

[@WilbertRamos777]

I purchased a box of 220gr UW ammo haven't shot any yet

[@jpg_sig10]

Awesome! This has been my wilderness trail hiking / biking and camping bear defense round, along with my anti-bear spray. Hope I never have to use it / them, but still, they're insurance. Thanks for you videos. Good things! 👍

[@tristantimothy1004]

JPG, Bad news, in a REAL bear attack spray is completely worthless & you'll never have time to use both. Shoot em in the FACE where they're brains at. Most folks don't know bears real anatomy. Skull Slopes sharply down behind the eyes & a center mass head shot is only jaw muscles which just pisses them off more. Even with their heart/ lungs shot clean out they can still live for minutes running on pure rage adrenalin & muscle memory & mess you up. A shot about 1/3 of the way down from the back sideways will shatter both shoulder plates crippling them so they can't still chase you. These rounds WILL go through both plates on even a normal grizzly. Bears ALWAYS die with their eyes OPEN. If they're close they're just trying to bluff you to getting closer so they can finish their attack.

[@tatumtactical5671]

What brand of bullet do they use so I can reload

[@davidsomerset8411]

Thank you great 👍 review I always wondered after it went thru 14 jugs... now we know...its an awesome round. Next shoot those 22 with the Buffalo Bore 44magnum 340 +P+ that would be extremely interesting 🤔 Buffalo Bore claims 100 fps more muzzle velocity than the Underwood 340 +P+ is why I chose it over Underwood.

[@jacobsobell4751]

Great video/test. Would love to see a similar barrel length .44mag hardcast comparison

[@freedomlover425]

So would I!

[@edwinrivera4869]

what pistol did you use? with original polygonal barrel?

[@paulhomsy2751]

I also have the same question, whether it's a stock or aftermarket barrel. The stock barrel doesn't always stabilize the 220 grains hard cast.

[@edwinrivera4869]

I purchase the Underwood 220 grain hardcast black cherry coated ammo. I shot one whole magazine of 15 rounds at a distance of 50 ft and all 15 shots were circular holes on paper Target and not a single tumble with my Glock 20 all original parts and polygonal barrel. I do not know or think that I would have had the same results with Buffalo bore or double tap ammo. Hope this helps.

[@justinpanizo1614]

Damn that’s some penetration I love the 10 mm. I remember when if u didn’t have at least a .44 mag for grizzly bears Alaskan’s would laugh at u.

[@O.E.M.MOE76]

Was that a stock Glock 20 you used in this video

[@freedomlover425]

It has a Lonewolf barrel. I haven't tried shooting the hard cast through the stock Glock barrel.

[@texasbeast239]

Since it didn't penetrate 14 jugs this time, this cartridge may have been loaded slightly less hot than last time. Or the polyethylene plastic of the big jugs may have actually been a little thicker and harder than that of the small jugs, after all. Either way, I'm gonna call this a good 13-14 jug round.

[@richardmarler8637]

Or the total mass difference between the different sizes of jugs made a difference.

[@texasbeast239]

@@richardmarler8637 - Perhaps the greater volume of water in the larger jugs also meant more internal water pressure. The big jugs are taller, and therefore have more water located higher within them than do 1 gal jugs, with their narrower throats at the top. This definitely means that at any given height off the table, there is even more water still above that in the big jugs than in the small jugs. And that means that the bullet had to go through a greater amount of water pressure resistance in the big jugs.

[@happytrails5342]

@@texasbeast239 as a scientist, ide say thats probably negligible.

[@matthall6974]

Great video! Have a Glock 20 and those rounds but haven't shot any yet.

It’s actually 215gr in actual weight and has 8.4 of Longshot in it ! Underwood Hardcast compared to Grizzly Ammo at 8.5 of LS with 200gr.

[@freedomlover425]

Any idea what pressure it's running at?

[@redteam9881]

Actual Velocity In underwood 220gr in 4.6” KKM G20 is 1134 FPS at 628 FPE as advertised at 1200 FPS @ 700 FPE. I reload 8.6 of LS to get the 700 FPE with 220gr in my G20 for Bear Load in Alaska. The Underwood and Buffalo Bore 220gr same velocity level. Only the Grizzly Ammo with 220gr Hard Cast has a closer velocity to the 1200 FPS advertised. Chronograph at 500 ft at 45 deg F in 4.6” KKM G20. Conclusion don’t believe published velocity on Ammo boxes until actually tested on chronograph. In 4.6” KKM G20 I can only get the 1200fps /220 and 1256 / 200 by reloading . 8.6 of Long Shot with 220 and WLP primer 14.0 of AA9 and CCI 350 with 200gr My best 700 FPE loads for Alaska Trail 30 year love affair with 10mm !

[@Finn-yg6zx]

Great videos on the 10mm underwood rounds. FreedomLover what will you be carrying in your G20 in grizzly country for personal protection? 140 grain xtreme penetrator or the 220 hard cast?

[@freedomlover425]

Thanks! It's a tough call. I actually was really impressed by the 115 Xtreme Defender compared to the Xtreme Penetrator. The 220 lead was amazing in the water jugs but not very impressive in the cinder blocks. I know cinder blocks aren't realistic to any bear parts, but it gave me the impression that the Xtreme Defender might break through bones better than the cast lead. Maybe I'd alternate those two. And pray!

[@redteam9881]

200/220 Hardcast is what we use in Alaska .

Good job !

[@freedomlover425]

Thanks for watching!

[@rodwspoon304]

Does anybody know if you can shoot these rounds though a glock stock barrel since there coated

[@texasbeast239]

Underwood claims yes. They say the coating prevents lead-fouling, so it's safe in a stock Glock barrel. Instead, it just causes red-coating-fouling! 🤣

[@rodwspoon304]

@@texasbeast239 hell yeah thanks for the info brother

[@Wildwestwrangler]

​@@texasbeast239underwood, buffalo bore and doubletap are all fine. You can't shoot lead rounds out of a stock Glock, but hard cast is a whole other animal!!! Anything with a brinel hardness 18 or higher will be fine as those three companies run theirs at 21.

[@Wildwestwrangler]

Regular cast lead rounds have a brinel hardness of about 11 and should not be shot in stock Glock barrels, but the Underwood's are fine.

[@texasbeast239]

@@Wildwestwrangler Much obliged. I remember reading a very informative website that talked about not going with too high of a hardness rating, but most commercial hardcast is fine. Can't find it again now, though.

[@Ty-tie_FTW]

That spot looks familiar. I'm in north idaho just a mile north of hayden lake.. cool videos, I use an xdm 10mm with 4.5 inch barrel. Curious to see how it does with these same cartridges. Also, I agree that this is a legitimate test. I shot a hydrashok 180gr into a 1gal jug of water with a 2x6 behind it and it went into the jug, expanded, and bounced off the 2x6 and hit the ground about 10 feet away from me

[@freedomlover425]

You have probably been to this spot! How do you like the XDM?

I test fired 2 rounds of the grizzly 220gr hard cast out of my xdm and it severely leaded my barrel. I really wish I could get some underwood right now...

Sorry if I didn't catch it but I was wondering if that was a Glock 20 you were using?

[@freedomlover425]

Yes it is. G20sf gen3 with lone wolf barrel. Thanks for watching!

[@josephmccabe4298]

People have been telling me I can’t shoot these rounds out of the stock barrel. Is this true or just total bullshit?

[@dsavv]

Completely depends on the gun you have. The Rock island armory 1911 in 10mm was built to handle full power loads, which is what I own so I dont have to worry about it. I heard that the glock 20/29 might need a better recoil spring.

[@nirv]

I have a Glock 20 and have shot some of these rounds (less than 10) at the gun range. When I was done I cleaned the barrel and it was fine. They say that the lead of the hard cast gets caught up in the polygonal rifling inside the stock barrels, and the KKM barrels don't have that polygonal rifling. The solution is either buy XTreme Penetrator 140g from Underwood which are fine to shoot unlimited out of the stock barrel and have comparable penetration results, or pay extra for another barrel and use hard cast. People say hard cast is SLIGHTLY better but they say the XTreme Penetrator rounds are about as good, but they're a little more expensive. I go with the 140g XTreme Penetrator even though I have 4 boxes of hard cast. I don't really want to buy a new barrel. I think it'd be fine to shoot a few hard cast out of the stock barrels but don't make a habit out of it.

[@texasbeast239]

My understanding is that when the Glock manuals tell you not to use lead rounds, they are referring to unjacketed, uncoated, bare lead rounds. Miniscule amounts of lead get scraped off the surface of naked rounds and then get deposited behind (as "leading") inside the rifling. Supposedly the polygonal rifling of Glocks fits closer against the sides of the bullet than standard button rifling, so when that minuscule amount of lead gets left behind, it doesn't take long to clog up the minimal gappage and build up pressure to the point of overpressure and kabooms. But UW works around that by coating their hardcast lead rounds with a bright red layer of lubricant. And supposedly this prevents the lead from ever coming into direct contact with the rifling, thereby preventing overpressure kabooms. Allegedly.

[@trumpie5399]

Hard cast bullets leave less residue than soft lead bullets. The best bullet is from Straight Shooter 200gr 22 BHN hardness and Cherry coated same bullet Underwood uses with BE-89 powder.

[@russhayes4882]

Heck yeah

[@davidortiz9859]

Is it true that hard cast bullets loose their tensile strength after some time? It would be great to find out I carry a 40 with 200 gr hard-cast from double tap at 950 ft at the muzzle, that’s my deep woods carry I hate to one day need them & the bullets fail to penetrate because they lost their ability to stay as a solid as they were intended to do so

[@freedomlover425]

That's an interesting question, I haven't heard that idea before. I'll send that question to Underwood and post what they say.

[@freedomlover425]

No response from Underwood, but I did some other digging. I have to admit I had never heard of the hardness changing over time, but from the papers I read it appears Lead-Tin alloys soften over time but Lead-Antimony alloys actually harden over time. Here's an interesting read: www.lasc.us/HeatTreat.htm Hope that helps, thank you for watching!

[@richardmarler8637]

Everything deteriorates over time, it'd probably be a good idea to change out your "life or death" ammo every year; why take the chance? This will also give you a great opportunity to shoot this hot ammo and stay familiar with it.

[@JohnB-dr8sk]

@@richardmarler8637 Unless you have money to burn, changing out every year is expensive and completely unnecessary. Every 5-10 years is more realistic. Modern nickel plated brass ammo is good for 40-50 years provided it's not submerged or stored openly in a high humidity environment.

@Tripleblade 82 I know the 220gr Buffalo Bore has a lot of cycling issues with a stock Glock barrel if you search for reviews of it on KZbin. That might also be the case with their 200gr. My recommendation is to go with Underwood 200gr Hardcast or Penetrators, or get a bonded heavy FMJ round from Buffalo Bore.
