I really appreciate people like you, Simple Minded Fella, capandball, etc. (yt channels). I'm constantly looking to learn more about all aspects of firearms and content like this is invaluable in my eyes
*ZINC alloys called ZAMAK 2 or ZAMAK 5 {formerly known as Kirksite} have about 4% aluminum and about 2.5% copper and traces of other metals... "Zink Aluminum Magnesium And Kupher [Copper]" ZAMAK 2 Brinell hardness in excess of 90... Home brew alloy similar to ZAMAK 2 is approximately 96% zinc pennies with copper coating of 2.5%... alloyed with 4% aluminum cans.* Aluminum cans contain small amounts magnesium and other metals...and a vinyl coating which burns off in the melting process... Caster's note: Aluminum will dissolve into hot liquid zinc... at well below the typical melt temp for aluminum. CASTING ZINC IN ALUMINUM MOLDS....IS A VERY BAD IDEA....because aluminum will dissolve in liquid zinc.
These were not casted in aluminum. And according to my test results I had sent for the Zinc Wheel Weights. They did not contain anything you mentioned above. BHN of 78 to 82 on average which is softer than copper bullets
@@EagleEyeShooting I wonder what is would take to make a small scale injection molding machine? Ideally we would use ceramic molds and valves and nozzles.
WOW!!! I think screaming is an understatement!!! 🤯 I think you’d get close to the same effect with a flat nose solid at that speed. I agree that the lead at 900 might stay together. I’ve never had any luck with lead HP in any of my handguns at higher velocities. Great info 👍🏻👍🏻
Thanks Mike Treen! Yup Those zinc bullets are awsome. So much less recoil, fast and devistating. When milliseconds count in a match and fast follow ups Im surprised not many have tried zinc. There really accurate also and no lead issues or barrel wear. Frankly I can't find much negatives
Hey Timothy Robinson. Thanks! I didn't forget your request. Soon as I get an optic for my 6mm Creed ill be stretching that out to 1k along with two others. If I recall I believe you where looking for a cast 380 round for self defense? Are these able to be loaded in 380 being the bullets are .546" long? Would be interesting to find out for 380acp. I was debating on getting a SIG 238
When I get around to it. Im going to try the Sierra MK HP 110gr and also the Hornady ELD Match 108gr BTHP using Varget or IMR 4350. The BCs on these bullets should buck the wind ill need to get around 3100 fps so the load is going to be hot. I converted 243 cases to 6mm using the Hornady Custom Grade die set.
Hey Willie Bulletman! Thanks brother! if your interested ill send you some? Got that thermo coupler you sent and yup it sure is working better thank you. Hope your recovering well bud.
Very interesting results and well done video! My only thing I didn’t agree with is how you weighed the retained weight, I think you should have only weighed the bases and not the parts that broke off, they Bullets did not retain their hollow point so I don’t think the extra pieces should have been included. But it’s your experiment and it was great
Whats up West Desert Shooter! Ha your right hence the word "retained" weight. Ill have to test these out on some clear balastic gel.. So RU-vidd For some reason dubbed the clarity of the video the still shots where alot clearer on the raw footage that was uploaded. Thanks for dropping by!
Awesome Video, A guy I use to shoot pins with would cast an aluminum and I believe it was mixed with a zinc alloy in 357 mag, it was a spire point and weighed about 45gr If I remember right, I do believe it was pushing 2200+ fps out of a 6" 357 mag barrel and he couldnt push it faster without the bullet coming apart in flight, very mean looking projectiles I must say, I am still keeping an eye out for spire point casts
Very interesting test. I’m impressed with the zinc for sure. I didn’t realize how much lighter than lead it was, I’ve just heard it was hard to cast. Do you think it’s harder on the molds? The wheel weights I’ve been collecting have had less and less lead in them and I’m thinking in years to come I may have to find an alternative. So, thanks for the great video! And getting my mind churning:) keep up the great work!
Jeff Huntley, Zinc actually fills your mold a lot better once in the operating temp (750). It is harder on the molds for this reason. And it flashes over very quickly making it difficult to cut the sprue and possibly damage your mold. Ideally a sprue plate with a 100 thou opening will benefit greatly for zinc boolit casting, as well as using a steel mold. Zinc is a differnt ball game and it deffinatly takes some practice to get a method going. Theres a lot of benefits that can outdue traditional lead boolits in accuracy as well. Thanks for watching!
Jeff Huntley it is way harder on aluminium molds. A guys who had a mold partly dissolve in zinc at around 900f. Way under aluminium's melting point. Zinc is very reactive. You basically need all your equipment to be ss and ceramic plus pressure fill to get consistently good results.
I guess ive been lucky lol. Ive casted nearly 1500 rounds of zinc 9mm from a cheap two cavity 124gr FN TL mold. Consistant 95.3gr but it took a while to get a good technic using a laddle
So a lee 4- 20 bottom pour furnace won’t do the trick then? I usually shoot my cast projectiles to save money. Wrinkles don’t bother me too much. Gonna be hard to set up the turkey fryer with the foot of fresh snow in the yard:)
There's more to it than density. Zinc wants to form crystals, and due to it's reactivity, it is extremely prone to form alloys with contaminants. It makes for a brittle bullet that tends to have voids. Aguila and others have commercially manufactured zinc bullets, but I don't think it is ideal for us bullet casters. The copper lead tin alloys have a lot of potential for rifle bullets that need high hardness.
*I would slow those Zinc Bullets down.... OR USE A LEAD Lyman #2 ALLOY {or hardball alloy. I have read or heard that unlubed ZINC does some odd things at or above 1600 fps. Melt, turn into a toxic blue vapour, foul the bore, etc. IF I were to use Zinc for bullets... I would grease them much like I do with lead bullets.... with Lyman Black Super Moly bullet lube (which looks like grease) in a LYMAN LUBE SIZER. Black Super Moly lube is meant for rifle velocities, a bit messy, will work in pistol or rifle, and will flow through sizer at 70 degrees [comfortable room temperature] without a lube heater.*
Interesting. I hope to get more into it soon just moved however Winchester just jumped on board the Zincer train in 45 acp. How about some commercial grade zinc bullets link below. 10mm seems to push over 1600 easily and these are said to work great well close to 2k www.midsouthshooterssupply.com/item/00247p10mmzs100/10mm-point400-diameter-155-grain-lead-free-zinc-solid-bullet-100-count
IWatchedWhat, These are casted from a Turkey fryer at medium high heat. Havn't really checked the temp lol. Its a challenge to ladle pour these and get a good fill
Hey Loads of Bacon, They are proposed wheel weights. I bought the ingots off an ebay seller. I was comparing these to your spread sheet. Since my kids misplaced my lee hardness tester scope im going off my last lead test. What are your thoughts?
I was really surprised by your FPS with the zinc bullets. I haven't found a good alloy/HP design combo yet for this caliber that will mushroom without fracturing at >1,000fps. I'm not done testing yet, but I'm thinking the HP design, and how thick the nose material is, will have a lot to do with it. I have an NOE 9mm HP mold on the shelf that I haven't cast with yet. The testing is fun. Good video!
