[QUOTE="dakor, post: 138804, member: 2204"] Well I went out and shot Sunday and it was -5 when I started. I ran my load through the ballistic calc the day before and it said I needed 78 clicks to hit the paper at 1000 yards with the 6-284 and 105 Berger. I fired 6 shots drove up to the target and could not believe I did not even hit the back stop. I went back to 1000 and clicked up two more on the scope fired a shot then drove to look again nothing. I had did this process until one landed on the paper. For the life of me I could not figure out why I needed 86 clicks instead of 78 a full 2moa short. Well I graphed the load and I lost 80fps from the last time I graphed the rifle. so instead of 3205fps I was only getting 3125fps. Made a big difference. What I really do not understand is this was with H-1000. So I did a little test yesterday. I left the rifle out with 4 shells out in the cold for two hours then graphed it. It averaged 3125fps on the money. I took the rifle in and let it warm up and shot 4 shells that were room temp. Same average 3125fps. Only thing I can think of is that the day I graphed the load the graph did not give me an accurate reading. Looks like I will be doing more load work. You might want to re graph your rifle. [/QUOTE]
