Use data attributes for the options

<?php 

$data = [
            [ 'id' => 1, 'rifleName' => '.308 Bolt action', 'em' => '225', 'gm' => '1350' ],
            [ 'id' => 2, 'rifleName' => '7mm magnum',       'em' => '300', 'gm' => '1575' ],
            [ 'id' => 3, 'rifleName' => '.243 LeverAction', 'em' => '215', 'gm' => '8725' ]
        ];

    
?>

<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
<script type='text/javascript'>
    $().ready(function() {
        
        $("#menu").change( function() {
            let em = $(this).find("option:selected").data("em")
            let gm = $(this).find("option:selected").data("gm")
            $("#em").val(em)
            $("#gm").val(gm)
        })
    })
</script>

<select class='nameItems' id="menu" name="selection">
    <option value="">Choose a Rifle</option>
  <?php 
        foreach ($data as $row) {
            echo "<option value={$row['id']} data-em='{$row['em']}' data-gm='{$row['gm']}'>" . htmlspecialchars( $row["rifleName"] ) . "</option>";
        } 
   ?>
</select>

em:<input type="text" class="charge-type" name="em" id="em" value="0" disabled size="5"/>

gm: <input class="charge-type" name="gm" id="gm" value="0" disabled size="5"/>
