In theory, if the pellet probe was a similar size to the pellet, it would "hold back" the force of the spring loaded revolving mag from closing on the skirt of the pellet.
Most mags seem to be spring loaded because it is easier than making a mechanism in the breech to revolve a mag. The earlier Wildcats used this type of system.

Iāve only ever owned one revolver, a Taurus Raging Bull in .454 Casull.
Once the bullet left the cylinder it crossed a tiny gap (less the a mill) and entered a cone shaped area called the āforcing coneā the mouth of which was slightly bigger then the bore, and just incase the cylinder hadnāt locked up and aligned correctly, it āforcedā the bullet into alignment with the barrel as it passed through. It was only about 5mm long before the lands and grooves started but it seemed to work. From the many hundereds of reloads I put through that revolver, (shooting a 375gr lump of lead, from a hand gun!!!) I canāt recall any flyers, it must have worked. I wonder if air rifle manufacturers have ever tried a design like that. All it would require is a slightly longer pellet probe to push through the additional 5mm, and a slightly longer stroke of the cocking/loading action. |

Hi Paul. Yes, damage from the challenge gun and a few others during initial scope alignment. I really should be doing that outdoors with a big backing board but that's too much hassle. I also have a couple of the Orion Iguana mags in bright green so there's no mistaking which gun they're for! Very similar to the STUD mag and the same price.

As a side note, revolvers, which is the closest to the mags used in this example do not preload the bullet into the barrel. All alignment is done in the cylinder with the bullet being left to jump the gap between the cylinder and barrel. It is ready lined up before a huge force creates the jump.

Don't know anything about the fx but my gamo was damaging pellets off its mag system.
It would seem to me that any system that requires a pellet to be pushed through one chamber to another with no way correcting a slightly off line pellet, weather it be it was undersized, or oversized, it runs the risk of damaging a pellet. There is also the problem of the probe possibly not fitting a pellet as well as it should (no one seems to make pellet specific probes) (I'll have one for hades and one for AA field in 22 Pauly š) and causing a pellet to move from the mag to barrel.Espially if there is a big lead in to the rifling. Even in single shot with the 1322 I have times when the pellet starts grab as I push it with the bolt. To correct this I point the gun down and correct with my finger, where upon it tends to fall happily all the way into the barrel. Air rifle mags don't load a whole cartridge and as such don't have a long brass cylinder to help with alignment. Any misalignment is going to directly affect the projectile. Though this can be reduced with tight tolerance on parts, if your not sorting pellets you still run into the issue of missized pellets. I'm assuming a slug would receive damage along the sloped edge and nose if this were to happen. This is my view and I have never done any testing to back this up. I think any mag has the potential to damage a pellet and the alignment of the system and the amount of play between the mag and rifling engagement is going to be a big factor in this. As I said, this is speculation on my behalf and is not backed up by any data I have to hand. |

Anyone tried the STUD mags?
https://www.dlhdev.com/ He reckons the FX mags damage slugs / pellets causing accuracy issues and these mags are the solution. https://www.youtube.com/watch?v=x_U-133bMTg&t=632s

Great job there. I'm guessing the hits around the edge are from testing the $100 gun?
The WC looks great. I got a couple of printed mags from Orion Iguana for mine, and they are really good mags if you are ever after more.

Just for you Pete! Currently fitted with a DonnyFL suppressor and my Vixen 4-16x44 scope. I have a Pard DS35 for it as well but I'll start with the standard optics. |

The metalwork from a couple of cheap mouse traps repurposed! When I get around to filling all of the collateral pellet damage and repainting the front panel I'll relocate one of them to the top center position and remove the second - two is overkill :) I used these as they were cheap and I figured they would be less likely to cause ricochet issues than say a pressed steel paper clamp. The Coreflute sits in a slotted piece of timber at the base.
