realistic velocities for .223 88 eld?

[mpwolf]

Got a 21" 1-7" .223 barrel coming for the Tikka. The idea is to feed it 88's and kill stuff. Up until now, I've been shooting 75 amax over Lever out of a stock 1-8" Tikka tube, at 2900. I haven't messed with anything heavier in the .223 before, so I really don't know what sort of velocity I should be looking for. Maybe 2650-2700?

Hornady has data for 5.56, 20” barrel. I’d figure 2725 ish for max with varget.
