I tested a batch of .223 loads today in my Rem700. I don't know whether to be disappointed in the gun, the loads, or myself. I'm a newbie at bench shooting, so it could very well be poor techique on my part. The best I could get was about 3/4" groups. I loaded three cases at a time with specific bullets and incremented the charge to see what it liked the most. I used unfired Lapua brass that has only been trimmed and the necks chamfered. I used combinations of Berger 55gr match and Nosler 55gr Ballistic Tip with H9548 and Accurate 2460. Maybe I'm not using the right powder and I do have several different ones, so recommendations are readily accepted. I did check the loads for runout and there was what I thought was significant runout several thousanths on some, condsidering I'm using Lapua brass. The process was to see which powder shoots the best in this particular gun, then tweak it with variations in the powder charge, then try different seating depths. BTW, the seating depth on all of todays loads were touching the lands, determined by using a Hornady OAL Comparator and calipers. I also cleaned the barrel with Rem Bore Cleaner and Shooters Chice and pusded a clean patch through before each group. I also sent one fouling shot down the tube after cleaning, trying to keep everything as consustant as possible. One thing that I didn't do, now that I look back, was to rotate the case in the shellholder while I was seating the bullets. I just set the bullet on top of the case and slowly raised the ram.(Rockchucker)
Since I'm not happy with the way any of them shot, I'm thinking of running the same test with this brass, paying more attention to the seating progress, now that the brass has been formed in my gun, and see if the results are different.. I'm just going to brush the case necks and clean up the primer pocket for this loading. Any thoughts from you gurus who have already pulled out all of our hair over this type of foolishness?
