There are two methods, check if they’re feasible for your requirement:

1. Edit the new form page and insert Content Edit web part, add javascript code to get column value from another list and populate it in current form.Similar post for JS

2. Use InfoPath to customize form, add master list as secondary connection and set the column default value with the master list volume value. Similar post for InfoPath

Answer 2

You can retrieve user Login and User Display name and then you can use function(below) to resolve people picker.

var currentUserLMEntry = createUserEntity(currentUserData.managerLogin, currentUserData.managerDisplayName);
function createUserEntity(userLoginName, userDisplayName)
{
return {
  Description: userLoginName,
  DisplayText: userDisplayName,
  EntityGroupName: "",
  EntityType: "",
  HierarchyIdentifier: null,
  IsResolved: true,
  Key: userLoginName,
  MultipleMatches: [],
  ProviderDisplayName: "",
  ProviderName: ""
};
}
