I have seen no differnence between the Ballistic tip and Accubond as far as expansion at low velocity. Also never noticed a dramatic difference as far as how quickly the bullets expand to to what diameter.
The only difference I have seen is that the Accubond will expand to a certain point and then retain more weight. In some instances, the Ballistic tip will turn itself totally inside out and shed a good deal of its lead core, the Accubond will not do this.
I would say if there is any real difference, it would be seen at close range impacts, not long range.
Just what I have seen.
Allen Precision Shooting
Home of the Allen Magnum, Allen Xpress and Allen Tactical Wildcats and the Painkiller Muzzle brakes.
Have used a 06 for target shooting past 800 yards
in local matches and then used the same rifle for
hunting with the same bullet all data was used for
both. Pick a bullet with a high BC, like speer 180 BT .540bc
The rifle is a tikka 22 inch barrel stainless with a mildot
scope that has come up knobs for windage and elevation.
This allows me to use the rifle to measure kill zones on
different animals to find range of target. Use information to
measure wind on site and different forums.
With RL-22 shoots a sub min [ less than 1/2 inch ] @ 2750 +fps.
I was at the range the other day with some friends and one was testing out his 30-06 with 165 grain ballistic tips. His second shot was at 2800 fps and the bullet completely exploded on the target at 100 yards. It literally splattered all over the target and left a shotgun like pattern with lead splattered around it. I have never seen anything like it before. I have heard horror story's of ballistic tips exploding on game at high velocities causing extreme damage but this was at a reasonable speed. I'll stick to partitions and accubonds.
I know this is probably a fairly old thread and has likely long sense been dead but it came up fairly quickly in my google search and thought I might add a few helpful links for those who run across it after me in search of guidance regarding this inaccurate old mans cartridge I hope I see a resurgence in it personally!
