mcseal2 I just happened to check the Nosler 7 book and your figures are spot on for the BC's of the Ballistic Tip and the Accubond. Bigsky I too have had great luck as several other poster's here mention using H4831SC in a friends .270 I load for him. I worked up his load using Federal 215 Magnum primers. IMR4350 seemed to work as well working up my load using Federal 210 primers. The H4831SC load came first though and it worked so well I just left it alone.Unless Nosler changed something or my memory is off I think the BT has a .456 BC and the AB has a .496 BC due to the thicker jacket making the bullet longer. I don't have my book right here to check it but I think that is still accurate.
That sounds like a good plan. I have switched to 225 Accubonds in my .358 JDJ, but have a few hundred 115 gr. Ballistic Tips to shoot up before switching the 25/06.I bet it would be darn close it you try. I think they have improved the ballistic tip greatly, but the results I've seen from accubonds are good enough I'll never use ballistic tips for big game again.
