Never good enough

We are constantly working on improving existing slugs. Working on expansion at lower velocities, which is critical for successfully LR hunting. Expansion test in clay at 750fps with 33 grain slug.

ZAN,

thank you for serving US airgunners during the pellet drought! 👍🏼 You are a great option for JSB pellets: With a large enough order the international shipping costs are reduced, and I keep hearing that you deliver very quickly. 👍🏼



🔶 Tip: To help airgunners order from you, maybe post a weight-to-shipping-cost table on your website. Something like this:

Weight | Cost

up to 1.3lbs $15.50
up to 2.0lbs $28.30
up to 5.5lbs $35.00
up to 12.8lbs $42.40



That way we can calculate how many pellets we can order without going over the weight limit for the next higher shipping price.





🔶 Very impressive photo of the slug expansion in clay. Looks cool! 😄

What most of us are concerned, of course, is with hollowpoint slug expansion in FLESH (and the resulting permanent wound cavity, the latter being very difficult to measure, as flesh/gel is elastic and behaves totally different from clay).

Since most of us are lacking the desire to mess with bloody cadavers, a close equivalent would be to measure the expansion in flesh-like material — like BALLISTIC GEL 10%.

(Because clay is much more dense than flesh, it results in huge HP expansions and "wound cavities" that will be much much better than in real flesh/ ballistic gel.)

If your testing provided shooters with a list of minimum impact velocities off different slugs at which they will still expand significantly — that would be totally awesome!! 👍🏼 Something like this (yeah, I like tables, thanks for asking):

ZAN slug .22cal, 33gr

Impact Velocity | Expanded Diameter

733fps 0.231"
752fps 0.260"
812fps 0.375"
905fps 0.388"
945fps 0.404"



Here are some examples of actual slug expansion tests, with all the data that would interest a shooter:

Keep up the good work, ZAN! 😊

Yes, shure agree about shooting it in the clay. But clay gives you actual size of wound chanel after the shoot, and it is homogenic material and does act the same when comparing with other projectiles. Animal flesh is the most similar to gel but stil it has bones and more/less dense areas. So for testing/comparing purposes you need to get same time same material properties, animal flesh doesn't gives you any comparison to other projectile.

Qball polytip story is little harder then it sounds "just adding tip on" it doesnt work that way.



Kind regards,

No.

Clay DOES NOT give you actual size of wound channel. 

Granted, clay is relatively homogeneous...but that's irrelevant.

Modeling clay is inelastic and essentially powdered rock.

It is useless for trying to predict how a projectile will act in an animal.

Trust me.

I'm an avid hunter and projectile tester.

The most accurate testing I've done, meaning the result of the test was reflective of wounds observed and projectiles recovered from animals, was in meat.

The second most accurate is 10% ballistic gel.

The LEAST accurate was clay.

Just trying to help.

Hi Donnie,

Misunderstanding, we dont want to predict size of the wound chanel in the animal but we are looking which slug shape will make the biggest. That will be different in the animal, but more or less parallel with the clay result. Clay or ballistic gel is homogenous so you can get same environment every time to make true comparison. Every slug in animal will act depending many things so this doesn't give us true comparison feed back. 

Every material is perfect for specific data you need, but shure not all.

Slug on the picture was shoot in ballistic gel

Completely understand your testing process. Your using the exact same material to test different materials and shapes of slugs/pellets to see which one yields the greatest expansion. I think a few users mistook your pictures as a representation of a wound cavity. A wound cavity would be done in ballistics gel for a proper comparison to flesh. Using clay as a testing medium for comparing projectiles is scientifically sound as long as you control the test environment. Meaning weight, density, moisture, shape, room temperature, humidity, etc. It's also cost effective and let's you spend more on research. Keep it scientific and your results reproducible. I look forward to hearing more from you.
 
But how well do these slugs perform on the world famous Paul Harrell "Meat Target"?

What is a "meat target" you ask?
It's a leather jacket skin, followed by pork chop pectorals, a layer of pork ribs, a bag of oranges to simulate lung tissue, more pork ribs on the back, four layers of tee shirts, followed by the new-and-improved high-tech fleece bullet stop. --Paul Harrell
