Boattails are a lot more popular due to the higher ballistic coefficient fad these days, but if you're not shooting at very long range, the BC advantage doesn't amount to much. I've seen very good accuracy with a number of boattail bullets, but if I have a choice in initial load development, I'll try the flatbase first. A couple of examples I can think are the Sierra 117 GameKing vs. the 117 ProHunter and the 180 GK vs. the 180 PH. I've experienced at least slightly better accuracy with both aforementioned PHs in comparison with the GKs. I think both PHs have been discontinued. Most people just prefer the boattails.
