DETAILED DESCRIPTION
(12) Referring to
(13) The die housing 12 is generally elongate and has opposite first and second ends. The die housing 12 defines an elongate or longitudinal bore 20 having open ends at each end of the die housing. As will become apparent, the longitudinal bore 20 receives various different components of the bullet seating die 10 and the bullet 1. In particular, the die housing 12 defines (broadly, at least partially defines) a bullet receiving space 22. The bullet receiving space 22 is a portion of the longitudinal bore 20. The bullet receiving space 22 has an open end (e.g., an open lower end). The case 2 moves through the open end and into the bullet receiving space 22 when the bullet 1 is seated in the case. The open end of the bullet receiving space 22 is generally coextensive with one of the open ends (e.g., the lower end) of the bore 20. In the illustrated embodiment, the die housing 12 includes a generally cylindrical side wall 24 defining the bore 20. The die housing 12 also defines a side window 26. The side window 26 is in communication with the bullet receiving space 22 (broadly, the longitudinal bore 20). The side window 26 is sized and shaped to permit the bullet 1 to be inserted therethrough to position the bullet in the bullet receiving space 22. This allows the bullet 1 to be inserted laterally into die housing 12, making it easier to position the bullet 1 for seating with the case 2 over conventional bullet seating dies. For example, the conventional seating die 4 shown in
(14) The bullet seating die 10 includes a seating stem 28 supported by the die housing 12. The seating stem 28 is generally elongate and cylindrical. The seating stem 28 (e.g., an end thereof) is arranged to engage the bullet 1 to press the bullet into the case 2 when the ammunition press 3 is operated. The seating stem 28 resists the upward movement of the bullet 1 to force the bullet into the case 2 when the ammunition press is operated. The end (e.g., lower end) of the seating stem 28 that engages the bullet 1 can define a recess sized and shaped to receive the tip of the bullet. The seating stem 28 is disposed in the bullet receiving space 22 (broadly, the bore 20). The seating stem 28 is positioned relative to the side window 26 in the die housing 12 such that the seating stem does not block or otherwise inhibit the bullet 1 from being inserted into the bullet receiving space 22. In the illustrated embodiment, the bullet seating die 10 includes a spring 30 that positions the seating stem 28. The spring 30 biases the seating stem 28 away from the open end of the bullet receiving space 22 (e.g., away from a lower end of the side window 26) so that the seating stem is positioned relative to the side window to permit the bullet to be inserted through the side window and into the bullet receiving space 22. The spring 30 holds the seating stem 28 up to keep the seating stem out of the way of the bullet 1. The spring 30 also allows the position of the seating stem 28 to be adjusted, as described in more detail below.
(15) The seating stem 28 is positioned, via the spring 30, to prevent the seating stem from blocking the side window 26 and inhibiting the bullet 1 from being inserted into the bullet receiving space 22. Specifically, the seating stem 28 is positioned within the die housing 12 such that the lower end of the seating stem is spaced apart by a sufficient distance from the lower end of the side window 26 to permit the bullet 1 to be inserted therebetween to position the bullet in the bullet receiving space 22.

(19) The alignment sleeve 60 includes a bullet retainer 64. The bullet retainer 64 is arranged to engage the bullet 1 (e.g., a lower end thereof) to hold the bullet within the bullet receiving space 22 when the bullet is placed in the bullet receiving space. Without the bullet retainer 64, the bullet 1 may fall out of the bullet seating die 10 (e.g., fall through the alignment lumen 62). By holding the bullet 1 in the bullet receiving space 22 with the bullet retainer 64, the user does not have to balance the bullet on top of a case 2 when operating the ammunition press. In the illustrated embodiment, the bullet retainer 64 comprises a cylindrical rod 66. In another embodiment, the bullet retainer may comprise a spring clip. The bullet retainer 64 is resiliently biased by a bullet retainer spring 68. The bullet retainer spring 68 biases the bullet retainer 64 into a retaining position (

(21) To change out the seating stem 28 and/or alignment sleeve 60 of the bullet seating die 10, a user removes the cap 48 from the end of the die housing 12. The user unscrews the adjuster 54 from the end of the die housing 12. This opens up the end of the bore 20 and allows the seating stem 28, the spring 30, the first spring retainer 32, and the alignment sleeve 60 to be removed from the bore. The seating stem 28, the spring 30, the first spring retainer 32, and the alignment sleeve 60 can all slide out of the bore 20 through the end previous closed by the cap 48 (e.g., the end opposite the open end of the bullet receiving space 22). After the seating stem 28 and the alignment sleeve 60 are removed from the die housing 12, the user can interchange the existing seating stem and/or alignment sleeve with another (e.g., different size) seating stem and/or alignment sleeve, respectively, as desired to configure the bullet seating die 10 to the desired caliber and size of the bullet 1 and the case 2 that are being seated together. To reassemble the bullet seating die 10, the user inserts the desired alignment sleeve 60 (e.g., one of alignment sleeves 60A-I), case guide section 52D first, into the bore 20 of the die housing 12. The alignment sleeve 60 slides down the bore 20 and engages the shoulder 64 of the die housing 12, positioning the alignment sleeve in the bullet receiving space 22. After, the user inserts the first spring retainer 32 and then the spring 30 into to the bore 20 of the die housing 12. Then, the user inserts the desired seating stem 28 (e.g., one of seating stems 28A-C) into the bore 20 of the die housing 12, making sure the seating stem is aligned with the opening 40 in the first spring retainer so that the seating stem slides therein. Lastly, the user reattaches the cap 48 to the end of the die housing 12. The user screws the adjuster 54 onto the end of the die housing 12. The bullet seating die 10 can then be mounted onto the ammunition press (if not already).
(22) A method of seating a bullet 1 in a case 2 using the bullet seating die 10 will now be described. The user configures the bullet seating die 10 by selecting the appropriate alignment sleeve 60 and/or seating stem 28 for the bullet 1 and case 2 to be seated or loaded. The user installs the selected alignment sleeve 60 and/or seating stem 28 into the die housing 12 as described herein. After the bullet seating die 10 is assembled, the user mounts the bullet seating die 10 on the ammunition press 3, as described herein. The bullet seating die 10 can then be adjusted to set the desired depth of the bullet 1 in the case 2. The user actuates the adjuster 54 (e.g., rotates the micrometer 56) to adjust the position of (e.g., move) the seating stem 28 relative to the die housing 12 to set the seating depth of the bullet 1 in the case 2. Now the ammunition press 3 is ready to seat a bullet 1 in a case 2. The user puts the case 2 in the ammunition press 3. The user also places the bullet 1 in the bullet receiving space 22. The bullet 1 is inserted through the side window 26 and into the bullet receiving space 22. The user inserts the bullet 1 under the seating stem 28, which is biased away from the lower end of the side window 26. Because the seating stem 28 is held up or biased by the spring 30, the user does not need to move the seating stem in order to place the bullet 1 into the bullet receiving space 22. This makes placing the bullet 1 in the bullet receiving space 22 easier over conventional seating dies. When the bullet 1 is in the bullet receiving space 22, the bullet retainer 64 engages the bullet to hold the bullet in the bullet receiving space. With the bullet 1 positioned in the bullet seating die 10, the user then operates the ammunition press 3. The ammunition press 3 may include a lever the user turns to operate the ammunition press. When the ammunition press 3 is operated, the case 2 is raised by the press toward the bullet 1 in the bullet seating die 10. As the case 2 is raised, the upper end of the case moves into the alignment sleeve 60 (e.g., the case alignment section 62C). The case 2 engages the alignment sleeve 60 and pushes the alignment sleeve and bullet 1 upward within the bullet receiving space 22 toward the seating stem 28. Eventually, the nose of bullet 1 engages the end (e.g., lower end) of the seating stem 28, thereby preventing any further upward movement of the bullet. Continued upward movement of the case 2 and the alignment sleeve 60 by the ammunition press 3 seats the bullet 1 in the case. The engagement of the bullet 1 with the seating stem 28 prevents further upward movement of the bullet so that as the press continues to move the case 2 and alignment sleeve 60 upward, the bullet deflects the bullet retainer 64 and is pushed into the case. The ammunition press 3 is continued to be operated until the case 2 is raised to its upper most point, which seats the bullet 1 in the case at the seating depth. The ammunition press 3 is then operated to lower the case 2. As the case 2 is lowered, the case brings the now seated bullet 1 with the case and the case and bullet withdraw from the alignment sleeve 60. The alignment sleeve 60 rests at the bottom of the die housing 12, ready to receive the next bullet from the side window 26. The user removes the seated bullet 1 and case 2 from the ammunition press 3 and then repeats the process with the next bullet and case.
