Pellet testing

Ran through 3 types pellets at lower  volicity.

That was inspired geniuses with the gel, created by the fact after cutting it up for lining the aircheif stock, I relised I hadn't taken the cocking arm into account and it wouldn't fit as I thought. So about then the gel shoe liner target came into existence. I seriously didn't think it would work that well.

same set up as above.

I do t think the exact will be any softer then the AA.
I know JSB claim they use separate and different dies for the AA pellets, so they MIGHT be ever so slightly different head or skirt size, but I don’t believe JSB melt up different batches lead with different ratios of tin and Antiminny for different customers. I recon they use a standard recipe, melted in huge caldrons and make hundereds of tons of lead wire which is used for any and all pellets they produce.

You’re doing great work testing pellets. Keep it up.

Pellets and airguns are strange bedfellows. I’ve seen airguns that like one particular brand but when the batch changes they hate them. A good example is my FWB Sport. It absolutely hated JSB then this year I got a batch manufactured in 2022 and it just loves them.
My HW97 loved JSB dated 2018 but with the 2022 batch I couldn’t hit a barn door at 10 paces.
I know guys who swear by AA. More likely it’s just a particular batch their gun likes rather than the brand.

Using plumbers putty for pellet trap.
Good trap too. Could suit those into testing for expansion.

Had a crack at 80m but wind is just too temperamental.
Had a thigh bone on top of breast bone, pellets kept hitting to side of thigh bone try again later if wind dies down.
Jsb/cometa exact heavy 10.34gr
80m.
Sig. 177
data per AA test.
Bone it went through is really thin like two playing cards thick.
Deformation not worth mentioning.
2 pellets caught in 4th layer one in 5th.
20m for comparison.
The grooves are filling out nicely with the skirt and the lands are just marking the heads so that's all good.

Have been toying with idea of hollowing out an alloy and replacing with lead. I have a sneaking suspicion that the lead will turn into a shower of fragments as it punches through the alloy on contact with the target.

I didn’t quite follow your thinking, are u talking about drilling out the front (making a hollow point, which is a bit of an oxymoron), or drilling out from the back into the skirt?

With my experience from powder burning bullets that use solids made from monolothic brass, copper, and even aluminum, and different construction techniques using harder metals combined with lead, u can either use the harder metal for controlling the expansion of the lead, or u can use the lead to add weight to the alloy for penetration.

If you drill out the front and make an alloy pellet into a hollow point, then fill the hollow point with lead, you will effectively have made a soft nose pellet.
When fired one of two things will happen: depending on the thickness of the walls of the alloy “cup” holding the lead, they could open up, deform, and give controlled expansion of the lead as the pellet penetrates and dumps its energy into the target, (this would be perfect pellet performance), OR, the lead and the alloy will separate on impact, the lump of lead will penetrate the target and the lighter alloy pellet will penetrate less (or not at all).

If you drill out the back of the pellet and fill it with lead, you have created a heavy alloy pellet, effectively a “solid”.
The alloy is very hard (but not brittle) and will not deform when it hits hard bone, and with the weight of the lead pushing it, it should penetrate like a MoFo!
I dont think the lead will smash through the head of the alloy pellet, u can’t use a soft metal to break through a harder metal, I think it will all hold together and just keep penetrating.

My 2 cents worth.
