Adjustable weight shot

Abstract

An adjustable weight shot system may include a core, inner and outer weight portions, and a body and cap. The inner weight portion may have two coupling hemispheres configured to receive the core in an inner weight portion cavity. Or the inner weight portion may be a hollow cylindrical portion configured to receive the core. The outer weight portion may have two coupling hemispheres configured to receive the inner weight portion in an outer weight portion cavity. Or the outer weight portion may be a hollow cylindrical portion configured to receive the inner weight portion. The body and cap may be configured to retainer the outer weight portion in a weight cavity defined by the body and cap.

         8 . The adjustable weight shot of  claim 7 , further comprising:
 a cap,   wherein the body is configured to receive the cap at an opening of the body.   
     
     
         9 . The adjustable weight shot of  claim 7 , wherein the weight portion is a first weight portion, the weight portion hemispheres are first weight portion hemispheres, and the weight cavities are first weight cavities, further comprising:
 a second weight portion configured to be positioned in the first weight cavity and comprising two coupling second weight portion hemispheres, the two coupling weight portion hemispheres defining a second weight cavity.   
     
     
         10 . The adjustable weight shot of  claim 7 , the weight portion further comprising a weight portion key hole. 
     
     
         11 . The adjustable weight shot of  claim 10 , wherein the weight portion key hole is formed near a boundary of the two coupling weight portion hemispheres. 
     
     
         12 . The adjustable weight shot of  claim 7 , wherein the weight portion hemispheres of the removable weight portion are configured to couple using a snap-fit connection. 
     
     
         13 . The adjustable weight shot of  claim 7 , wherein the shot cavity is semispherical. 
     
     
         14 . The adjustable weight shot of  claim 8 , the cap comprising a tool port. 
     
     
         15 . The adjustable weight shot of  claim 14 , the tool port comprising a tool port weight. 
     
     
         16 . The adjustable weight shot of  claim 8 ,
 the body comprising a cap seat extending radially inward from the opening; and   the cap comprising a cavity sleeve,   wherein the cavity sleeve is configured to engage the cap seat.   
     
     
         17 . The adjustable weight shot of  claim 16 ,
 wherein the shot cavity is semispherical and has a shot cavity radius,   wherein the cap seat has a cap seat diameter, and   wherein the cap seat diameter is greater than the shot cavity diameter.   
     
     
         18 .- 21 . (canceled) 
     
     
         22 . An adjustable weight shot system comprising:
 a cylindrical core;   a hollow cylindrical inner weight portion configured to receive the cylindrical core;   a hollow cylindrical outer weight portion configured to receive the hollow cylindrical inner weight portion;   a body configured to receive the hollow cylindrical outer weight portion; and   a cap;   wherein the cap is configured to retain the outer weight portion in the body, and   wherein the cap and body have a spherical shape when the cap is secured to the body.
