The accubonds are suppose to be a combo of the partition and the ballistic tip. Because of its (B.C.) a ballistic tip groups well at long range. Now as you already know a partition holds together through anything. My question to you is do you plan on shooting long range between 300-500 yards? Or do you plan on shooting 300 yards and under? If I was shooting 300 yards and under I would stay with the partition. And if I was shooting over 300 plus yards, I would use the accubond. I shot my first bull elk at age 13 with a .270 at 350 yards, using a junk 130 gr. remington corelock bullet. Now that I have a lot more experience, I would not make that mistake again and use a quality bullet. But on the other hand I would not shoot over 300 yards with any .270 no matter the bullet. That is why I own a .300 RUM, but I realy don't need it, being a bowhunter at heart I love to get close. But if I'm on a rifle hunt and the bull of a lifetime is 500 or 600 yards away I want a wepon that can kill him. Just to let you know I did shot my bull this year with a 180 gr. accubond at 70 yards. If you want the full story read my post (another successful season with pictures). I will post pictures of my recovered bullet in the near future. Thanks and good luck with your choise and hunt.
