Different Head Designs:
Nearly all modern pellets today take on the Diabolo shape - an "hourglass" design that was named after a spool shaped object used in the ancient game of Diabolo. The thin flaring skirt of the pellet engages the rifling of the barrel and acts as an air seal for best efficiency. A few pellets still use the cylindrical style with straight flat walls and a small ring at the bottom to engage the rifling. These pellet designs were most common with the Sheridan brand of .20 caliber pellets, and are not as prevalent today due to their generally poor flight characteristics.
The only difference between Diabolo designs is that some have smooth skirts ("glatt") while others have ribbed skirts ("gereffelt"). Both styles shoot equally as well, and Beeman has both models available.
The biggest difference in pellets comes in the head design. Pellets are generally classified according to their head shape since this feature has the most profound effect on performance.
Four Basic Pellet Types:
1. Wadcutter -- Pellets with a sharp outer edge; usually with a flat head that was designed to cut a perfectly round hole in a paper target to aid scoring. This is the style that Olympic competitors and other 10 meter shooters use. Many hunters also prefer to use a wadcutter in the field because of their excellent impact and limited penetration. The Beeman H&N Match pellet is an excellent example of this style.
2. Pointed -- Designed for maximum penetration and long range shooting. The best selling models are the Beeman Silver Arrow and the Beeman Silver Sting. These models are frequently imitated by others, but none has come close to the performance of the Beeman brands. Note: due to the head design, pointed pellets generally do not work well in the repeating mode of some airguns.
3. Round Nose -- Great for all-around shooting. They have low wind resistance and flat trajectory. The Beeman Laser pellet is lightweight and gives hyper velocities, while a heavier pellet, such as the Kodiak or Ram Point, harnesses the energy of high powered airguns for more consistent shooting.
4. Hollow Point -- First introduced to airgun shooters as the Silver Bear. We pioneered the hollow point concept to allow for the maximum impact from all airguns. This style has a direct relationship with velocity - the higher the velocity the more expansion will occur on impact. This is especially true with the Crow Magnum which can nearly double in size when shot with a magnum airgun. |
You wouldn't happen to work for Beeman, would you?    |

| And smart for using it off the Beeman site. There is a lot of useful information there. Saved you a lot of typing for sure! But some of the information is old. As we know know, round nose pellets are better for long range shooting....usually. But there is always the "favorite" bullet for each gun. I have an R1 in 177 that LOVES Cro Mags and that is "not a good Long range pellet". The reason pointed pellets don't work well in repeating systems has to do with pellet length, too long for the magazine or feed mechanism. |

RE adding bb's to hollow points.
Thill bobber company makes premioum lead bb's down to 1/64th of an oz size. These could easily fit inside a .177 hollow point with room to spare. Could do some experimenting with them. |
