Selling for component use only!
Data lists Hornady 180g SP and 59.0g IMR 3031 (???) I've noticed variations in the Weatherby brass, either due to improper resizing or bullet seating, but you should be able to fire-form or resize them correctly (no crushed/damaged cases).
You must pick up the complete rounds (132 available) or I can tear down all/some of these and ship the brass only (USPS Flat Rate).
Location SE CT; 100-meter range onsite, so you can shoot while here.
I'll do $1.20 per round. Brass only: 90¢ each, plus shipping.
