For added options, if you’re using a military discount I would definitely recommend meopta. I have used their mil/LE program several times; Erik is great to work with and their discount is generous. If I had your rifle set up and 1k budget this is the model I would go with (R1 4-16x44):

Another option is Zeiss on experticity. They have decreased their military discount to 20% but that’s still not bad. I have a Zeiss hd5 3-15x42 RZ800 on my 300 win mag that I really like. Again if I had your set up and budget this is what I would look at (conquest v4 4-16x44):
The balance between its wide field of view and magnification range make this compact riflescope ideal for all types of hunting.
