Want to pass along what the results are with my 280AI. After trying RL-22 and Retumbo, 160gAB and 168g bergers, win LRP and CCI BR primers, and setting seating depth from touching the lands .080 off the lands and every combo possible I found what worked best in my rifle. 168g berger .010 off the lands 61.8g retumbo cci bench rest primers This load shoots 1 ½” 5 shot groups at 200 yards @ 2875’sec. consistently. Howa 1500ss action 26” Pac Nor barrel Bell and Carson metalist stock glass bedded. Burris fulfieldII 4.5x14x42 scope with Burris signature rings with 15 MOA off set. I hunt in Wyoming every year between 6500’ to 9500’elevation with average day time temp around 35 - 40 deg. If I plug all this into a ballistics calculator I have a velocity of 1983’sec and 1467 ft-lbs of energy at 800 yards. That should be a good deer thumper. Unfortunately I caught the flu during this years hunt and spent 4 days in the hotel room. The day before the last day I finally went hunting. I had one buck tag and two doe tags and I wanted to salvage something out of the trip so I shot two doe’s out of the same group and I was done. I still was not feeling well enough to walk around looking for a buck. One doe was 241 yards the other was 175. These are the first two animals I have shot with Berger bullets. Both dead right there, neither one took a step. I hit one in the shoulder and it did seem to destroy a lot of meat. I won’t do that again at least on deer. No pictures, was not in the picture taking mood. Just thought I would pass along some information.
