Sigh one more thing to check.
Time consuming, not fun, always interesting, amazing some of the tins I've had,especially the cheaper ammo, why I gave up on gamo pellets. (Though the red fire and one with ball bearing in nose have always given me good results (but never the best). Still if I'm hoping to constantly shoot from 60m to 90m accurately better get rid of all the variables, so I can adjust what I'm doing and not blame a pellet for bad shots. |

For the odd bent skirt I use a dummmy 308 round with 130g speer hollow point projectile, which is perfect for pushing the skirt back into shape. Quick & simple.

Great idea!
Gawd dam right tool wrong tip. ![]() Whats the dimension of your bullet tip? Might be able to cut lead off top. (after I separate the powder and fire primer) |

So in the interest of getting the most out of me old work boots, decided to shoot them to see what differnt pellets did out of same gun at 10 pumps @20m.
Not overly exciting, penitration through leather, but that was it didn't make it through thin layer of foam or gortex lining. Pellet damage minimal with both the AA 16gr and h&n fft showing no ill effect and would have been reshootable. You can see the AA still in the leather on your right . Hades suffered enough skirt damage to not be usable again, and very slight head damage. But..... ![]() Due to the fact skin isn't dry I decided to soak the Tounge in water for 10min and see what happened. Hoping the hydrostatic shock of water in the leather would open the pellets up. The resault ![]() NOT ONE PELLET PENITRATED the leather. Go figure. Definitely didn't think that would happen. The gun is putting out around (slightly over or under) 7fpe with hades 15.89gr at muzzle, last time I did a reading on it. Edited by kruzaroad - 31 Jul 2024 at 12:46pm |

That will be the refrance to the formidable protection label. What ever the rubber it is on laughed at pellets. Bounced off that part without hardly leaving a mark.
Looking at the pic it's only a very shallow layer that's wet too. |

After the wet boot tounge results with the 1322,decided to try the same with hw97.
Set up is leather with foam backing then the boot innersole cut in half all taped together. Blitz through it at 36m wet or dry. Set it up at 80m caught pellets between front layer of sole and back layer. Approx 7fpe at target. After shot a couple of ftt which deformed f all, but had really nice rifling grooves in them, I thought might as well try a couple with a x cut into the head with stanley knife. Was hoping for a more expanded head with same penitration. What I got was unexpected. Not sure if one side shears off to the skirt or some thing else is going on. Did find some bits and pieces of lead in catch box. Didn't find additional holes or damage around the impact area. Any theories?

Wonder if I x4 cut from the neck of the skirt, up the back part of head to just below widest part of head if it would allow the front of the head to compress the under side and give better expansion.
Maybe tommorow |

Haha that leather is as tough as an old boot!!!
That's quite interesting, the fibers in the leather would make it almost bullet proof for airguns |

More so when wet.
Doesn't tear as much with just a mil or so of leather wet. I'd be rather interested to see what it would do on a fresh hide, at full thickness. You work skins bb, what do you think a pellet would pierce better? Thinned, worked boot leather or fresh hide of a deer? |

Soaking the lether softens it and makes it more supple, thus allowing it to absorb more energy from the pellet with out breaking.
If you dried the leather out it would become harder and more “brittle”, more likely to crack allowing the pellet to penetrate and would probably cause more deformation to the pellet. If you take those two situations to extreams, it’s like shooting a pellet into multiple layers of a hanging bath towel, will absorb all the pellets energy, towles will probably be fine and can probably reuse the pellet, vs shooting the same pellet into a 1mm thick galvanized sheet, damage to metal sheet, probably a hole, and pellet will be mooshed flat… |

Wet leather is definitely more plyable.
The extra engery it absorbs will vary on how loose the leather is. Tight wrapped it can't "give" as much due to tensed fibers. As both wet and dry were same distance and tension I see that theory as part of it. I think the swelling of the indervidual fibers also causes a denser matting (if that's the right word) of them, also making the leather denser than it was. Again speculation on my behalf. |

I remember hearing about if you shoot into a dry sheet hanging on a line the sheet will often catch the pellet. But if it's wet the pellet will pass through. Never tried the theory for fear of putting holes in my wife's sheets hahaha

Just claim it was moths. Lol.
So cutting under the head did nothing for expansion either. Did a couple of pellets each of a 4 and a 8 under cut. So disappointed and resigned to the fact I'm probly never going to get decent expansion without a pcp went onto something else I've been meaning to test. Dacron as a pellet catcher. After seeing how well the sleeping bag stopped crossbow bolts it's had me curious. So the non expanding pellets were shot into leather with a dacron backing at 10m from 1322. Caught them nicely. But hey the leather probly took some energy out. So I got rid of the leather, folded the dacron 6 layers thick, put it in my pellet trap (cheapo gun City thing that the rifles blew the back out of shortly after I got it and had to throw a couple of steel plates in.) pumped the 1322 up ten times, placed it an inch from the dacron, stood to the side and fired. Did it 5 times after no ricochet from the first. Though the pellet's would punch to layer 5 of the dacron, the pellet never got through the 3rd layer. Its pretty impressive stuff really. None of the pellets caught had any damage at all. You can buy the stuff. Some sleeping bags and cushions have it. The stuff I used was out of old cushions, but the sleeping bag will be getting pulled apart for target backing next fine day. 2 pics, two differnt shots. One to show how far it pushes into the dacron without letting through. (the next two layers looked the same) One to show the pellet caught and held and the indent into the other layers. ![]()

Kruza, don’t scorn your HW for not getting mushroomed deformed pellets, none of my PCPs or springers do either, (in a rabbit)
Seems u need to get a pellet moving well over 900 or 950fps to get them to mushroom in a “soft” target like a rabbit. Of course if u shooting something as hard as steel plate, a 4.FPE air rifle will get a lovely flat mushroomed pellet, but we’re not interested in shooting metal, we’re looking for perfect terminal ballistic performance in small game 😂 |
