I have been doing a lot of load testing and have found that the heavier bullets work much better at the longer ranges. I did a little load testing the other day to see just how varmint bullets would work at the longer ranges. I used 1 gallon Clorex bottles filled with water at 500 meters to see how the bullets would act at this range. I used 70gr TNT's, 70gr Blitzking's, and 105gr Amax's. The 70gr TNT's and Blitzking's blew up quite nicely but the 105gr Amax leveled the jugs. What a difference. I've found that the Amax's are very explosive, Just like a varmint bullet. This has to be one of Hornadys best kept secrets.
My 6mm Ackley has a 1-10" twist barrel and shoots the 70gr bullets fine but won't stableize the 105 Amax. My 243 Ackley has a 1-9" twist and does a great job of stableizing both bullet weights. I put 9 shots out of 10 into 9" at 1000 yards the other day and the wind caught me and blew the tenth shot out to 16"
Give the Hornady Amax a try. You'll get the best of both worlds. Long range and explosive.
Catch you later,

PS If you need some drop charts? I can e-mail them to you set up for every 50yds out to 1000yds. I just need to know the bullet and velocity. Also let me know what range you want it sighted in for. Also give me the MOA adjustments on your scope so I can give you the click adjustments. Or you can give me the load, bullet, barrel length, powder charge and I can figure it out myself. firstname.lastname@example.org
