Slug with a polymag tip?

[AirSupply]

Just mucking around and noticed the polymag tip fitted very well in my swagged slugs. It’s not a firm press in fit just sitting there. 
Wonder how it would work? Super high bc projectile?

You could get a die that would except the push in plug of the polymag. Would be fun to experiment with some different shapes. Would a 3D printer be able to make the tips?

Don’t no why that page at the bottom up loaded

I like it. Sacrifice a few poly mags, glue in the tips and give them a go! Actually, you could do 2 test. 1) Your new bullet 2) Polymags without the tips

Awaiting the results!!!!!

Thats a lovely looking projectile, Michael! I wonder could you make a mould that you could inject hot glue into to form a plastic tip? At airgun speeds and pressures I wouldn't imagine it would melt upon firing but I may be wrong.

nice This is just like the ammo for centerfires called ballistic tips or varmint rounds , I bet it should raise the BC , I think what mite be even better is making some out of alum to make them more aerodynamic , I my self like solid slugs but I do Like this better then the Big hollowpoints which are being sold , If I remember correctly isn't their a 35 caliber airgun slug like this?

I like it! Yup, little dab of something sticky and give them a go. You have me wondering if that would work with the Hybrids, they shoot pretty well out of my .22s

My only concern is fitting in the clip, pending the gun one would use.

There is someone on YouTube doing this, but I don't know the name of the channel.

Was hoping to test this today, maybe Friday. I made two of them. Looks promising. FX Hybrid .22.

Good luck! Can you record bc as well as accuracy?

Will get as much data as possible. Would have done today, but mother in law showed up for a visit .

I was thinking if there was a way to easily make different shapes it might be possible to do a push in boat tail. If a 3D printer was able to make them strong and accurate enough it would be much easier to experiment with different designs. Rather than have to have new dies. There might be an advantage in the add on pieces being lighter than the lead. It might be easier to get a good balance.

Well maybe just remind her about covid. A little bit of strategic coughing.

Hi James. I like your idea. There must be a simple way to make different shapes. My nephew has a 3D printer. I will have a chat to him. He could make the pin match the hollow points I already have. 
We could really ramp up in terms of slug design. 
You could have a lead core in the correct diameter and try various tips and tails to find what works. 
You could copy the shapes of the best Centre Fire projectiles and still be able to tweak the balance of the bullet with the plastic add ons.

These are .25 39 grain Griffins HRBT-Low Density Core- Ballistic tip. BC .133 on Hollowpoint’s & that tip adds up to 36% according to Labradar. If you can get them going 1032fps. 
I’m gonna be trying the 39’s, 50’s, 56’s and 72’s. Hopefully as fast as the 28-32 .22’s 1070-1040fps. 
Those Hollow Delrin balls are explosive.

That too is only supposed to cut through the wind for ballistic performance so wouldn't crayons do? Get the Crayola box with built in sharpener. Was should be less weight less wobble in its spiral flight?

 

[Yo]

Put them in a bucket of water and use only the ones that float. Read that the colors make some difference in density but IDK maybe only use certain colors or maybe it's negligible and won't matter?

Back when Rat Sniper was making slugs he had some slugs with plastic and metal balls in the hollow point. He claimed they promoted better expansion. I never tried them . 

 

[AirSupply]

Those Griffin slugs look amazing. He has done a great job with them. Obviously not a new idea. The bc is fantastic. How where they for accuracy?

Thanks for posting this had no idea these existed. I wonder how he made the ballistic tips? 

 

[JamesD.]

Don’t know how any of them make the tips but I need a windless day to test the drop of them against HP’s. 


If Labradar is correct and the tip adds 36% BC I should see at least one less mill of drop while tethered at 200 yards. 

I’m gonna end up casting but don’t want a ton of useless dies. 
I know I love the 2 stroke 28-32 grain RBT .22 Griffin slugs. 
I’m waiting for their short RBT 32 grain .25 to come out
