[QUOTE="Varmint Hunter, post: 34545, member: 313"] Break-in would be no different than for any other cartridge. I usually shoot once and clean for the first 5 rounds, then shoot 3 and clean for the next 5 groups. Lastly, I shoot 5 and clean for 5 groups. That should take 45 rounds. It bwill also provide you with a box of once fired brass and an idea of what loads look promising. Everyone seems to use a different break-in method but they are all variations of the same process. Either bullet should work fine for your intended game. The Accubond is harder and will provide better penetration while the Scirroco should give better expansion. If short range impacts are expected then I'd opt for the tougher bullet. The 160gr Accubond shoots very well from my 7STW and would be a good choice in any high capacity 7mm cartridge. The Hornady Interbond is similar to the Nosler Accubond but is said to expand a bit quicker and cost a little less. VH [/QUOTE]
