The rifle is my much talked about 223 Ackley Improved. Right now I'm shooting a Hornady 68gr Match Bullet at close to 3200fps (chrony) 10' from the muzzle. This load is not my best 100 yard load but the bullet preforms at distance very well. I'm planning to do a day long test. Start at 7:00am and find my scope settings. Do the same at 8:00am, 9:00am, 10:00am, on and on at appropriate times until I have a good bench study to work with. Right now I have scope settings established at 7:30am (temps. in the 70's - mid. 80's) or so and in the for trips to matches they were amazingly accurate but in the hour or so it takes to get the match started and my turn comes around (temps in the mid 80's - mid 90's) things change.
