Microscope pictures of FX 30 Cal 44.8 Gr and AEA 30 Cal 45 Gr

Just got a new microscope I've been wanting to play with.

On the left is:

On the right is:
AEA 30 Cal 45 Grain

It's interesting to see how different they are.

Hello @agn75433

That is neat ! The FX looks corroded up next to the AEA, that has to make some if only a little in better accuracy. Hope you do some JSB. Thanks for sharing.

Thanks!
I think that's a first on AGN — microscope photos of pellets!

Thanks for sharing. I have been very pleased with the AEA 45 grain pellets. With these pictures I can understand better why they shoot so well. Thanks again

 

[IMADMAN]

Any chance can you measure the head and skirt of each.
Just by looking at the pics, this is what I think I see-
JSB-larger head and smaller skirt
ARA- Smaller head and larger skirt
Does one of these shoot better than the other in your guns?

Don't we all?

Seriously, though, the images are really interesting. Quite a difference between what most are assuming to be "old" vs. "new" dies.

Those AEA pellets look like way better quality than the FX. Those skirts on the FX was to affect the accuracy. I looks more like the die didn't get cleaned out in to long of a time. That's mass production for ya.

This is a cool view of these pellets!
How does the bottom of the skirt of the FX look so crackedor layered?
is it left-over materials adhering to the next pellet?
I have some old JSB monsters before the redisign. Their shape is similar to the AEA

On the left is the original JSB Monster before the redesign and on the right is an AEA.
these are .22. The originals look similar to the 30 cal AEA

I’m using the same scope. I use my LabRadar battery pack to power the lower lights. I’m impressed by the uniformity of the skirt on the AEA. I didn’t realize that they had different skirt and waist designs

Thanks for the pictures, it confirms my suspicions. The AEA are a touch better than the JSB's

I can tell you that my Mavericks AND my JSAR Raptor LOVE the AEA's, they shoot just a very tiny bit better. Speaking of which....I need to buy more.

Softer lead (typically having less tin and antimony) will generally appear more hazy and dull and is also more susceptible to nicks, scratches and deformation. So the difference in the macro pics is not necessarily because of a worn or dirty die. It could just be softer lead. JSB does typically use lead that is on the softer side compared to many other manufacturers.

@Nvreloader has a database of pellet head and skirt diameters that he measured. Perhaps he would be willing to share those here. Or at least a subset, for the JSB and AA pellets mentioned above?

 

[TheRealHearkensSaltLake]

The AEA 45’s are super accurate in my FX until they throw odd fliers. Cant explain the fliers…

 

[MongooseV8]

Holy smokes what is that I want one!

This is correct. Also, the softer material will deform easier during shipment. These are not ‘straight from the die’ examples but have had a series of journeys getting to destinations. Oxidation rates are different as well.

One thing that does however indicate a worn die (possibly) is the parting line. This is evident in the 3rd picture down of original post. Softer alloys exaggerate these issues as it will flow into worn parting areas.

Does any of this make one better than the other? Only each gun can tell that story.

Curious if pellets that come individually packed like match pellets would have what look like little impact dents/marks caused during shipping, or perhaps if they are tumbled at the factories. And, what if any affect they have on accuracy. Pretty tough thing to really know for sure I suppose because every pellet would be slightly different, like a finger print.
Thanks to those that posted the images. I bought a regular old fashion microscope years ago when I repaired scuba regulators for observing defects in sealing components. I pull it out occasionally to observe things in great detail.

Not exactly what we would like to see, but perhaps useful?

The tray pellets do look better, not flawless, but better.
I have noticed that .177’s in cans seem to have much fewer damaged skirts. I suppose it’s because they are lighter in weight, but, they also put a lot of them in a can which makes the bottom layer particularly at risk for damage. I recently had a tin of .30 pellets that had about a third of them with severely damaged skirts.
