This is really the same die as the PF-1-SB (bleed hole, lead swage die), but with a designation that reminds us this is for an air gun, not a shotgun slug, or a black powder rifle bullet, or a handgun bullet. All of those can be made with the same style of die. The air gun slug is generally a hollow base with about 2-S ogive shape, with or without a hollow point cavity. But it can be whatever you wish.

Smooth ogive air gun slugs You do NOT need to enter specifications and dimensions if you select the standard caliber and shape from the drop down-menu.

If you WNAT to specify custom dimensions, you can use the input blank boxes. But be aware that custom work takes longer and usually has additional cosdt compared to the standard designs If you want either the solid ogive or the hollow ogive style in a standard shape, with a standard hollow point for the caliber, just use the first option selection (drop down menu with caliber, shape, and HP specs). Leave the base as a cup base unless you want some other shape. Then select the one you want. Changing the base to another standard shape does not make the die "custom". Entering specific dimensions to modify size or hollow point shape would be custom work.

The weight range is very broad. You can adjust it as you make slugs. The desired weight range input blank is primarily to let us know what you have in mind so we can ake sure to test using your extremes if they will work. Also it helps us know to contact you if you put down something that is not realistic, such as a 20 grain 350 caliber or a 200 grain .218 caliber. There are some limits imposed by physics and the guns themselves.

You do need to select either the solid or the hollow ogive. Default is solid. That means that if you select a standard with the listed HP dimensions, those are the HP dimensions you will get. If you select the HO (hollow ogive) style, then the HP dimesions beyond the meplat or width of the bullet tip are not applicable, since the hollow is an egg-shaped cavity larger in the inside than the opening. That can only be done by preforming the slug with a CSW-1-S die first and then rolling the ogive around in this die. So IF you want a die to make the hollow ogive type, selecting tha toption gets a different shape of ejector than the solid ogive style.

The difference between this kind of PF-1 die and the standard PF-1-S is that it has a pressure-sealing, synchronized length (to the depth of the die cavity) so that the chamber or cavity in the die is essentially sealed. The pressure you apply moves the lead to flow up and around any projection on the end of the ejector, which itself seals off the pressure so lead won't go up the ejection pin hole.

The "rod" part of the internal or ejection punch is attached to a "head" by a set screw, so you can replace it. The replacement would need to be a very specific length, held to the nearest thousandth of an inch, so the "sync length" is marked on the die and on your paperwork. It needs to be part of any future order for new or different ejection punches.

The base can be any of the standard ones in the drop down menu, or it can be a custom one that you design. Custom punches require more paperwork, shop drawings and machine time (one-off parts always take more set up time as a portion of total work done than a run of 1000 standard parts, for instance). So they do cost more to make, but the amount is still a lot less than trying to design and make one from a piece of steel, without the right fixtures, jigs, diamond laps, and years of experience. However, if you can use a standard shape and your custom design isn't much different from it, you probably will be better off to do so. Standard designs are quicker to replace in case your brother's little boy decides to wander off with a punch from your bullet making bench!

Smooth ogive air gun slugs This style of slug needs to be a good fit to your gun's chamber. If it is a nice, smooth fit without deforming when pushed home, it will probably be a good match to the bore as well. If it is too snug, you lose velocity and if it is too loose, you also lose velocity! The right fit is tight enough to keep the air behind it, but not so tight that the barrel grooves are dragging on the bullet full length. The rear of the slug will slightly expand by being squeezed between the sudden impact of air pressure against the temporary inertia of the slug mass. It isn't much mass, and the intertia is small, so the expansion is usually just fractions of a thousandth inch. But holding plus or minus 50 millionths inch on the diameter with the swage dies means you can, in fact, get just close enough to assure good air sealing with a very tiny amount of "bump up".

Folks often say that there isn't enough pressure to do that in an air gun. IF not, it might be a spring air gun rather than a PCP type, but still you can design the base so that very little pressure is needed to expand it into the rifling. On the other hand, you do NOT want the muzzle pressure, as the air escapes behind the pellet, to flare out the base! That can cause terrible accuracy, with the same pellet that would be a ragged-hole shooter if the "skirt" thickness around the hollow base were somewhat thicker. The exact amount of skirt thickness on a hollow base bullet is easy to change: just use a different base or external punch, with the diameter of the hollow base projection changed. To get the same weight for the length, you might need to slightly increase the depth of the hollow base to make up for the slightly reduced diameter of the hole. Smooth ogive air gun slugs

There are all things you can do to experiment and discover the optimum design for any specific gun and pressure, which are impossible to do with factory pellets (since you have no control over what they wish to use for dimensions, other than buying a different one that may or may not be exactly best for your gun). You can "tweak" the weight to match the air pressure and chamber, even with the same base and hollow point sizes. Or you can change either hollow point or base shape to shift the balance with a given weight. Or to make the same length weigh less or more! It's like a laboratory on your loading bench.
