It's partner, the flat based .451 290 grain shot a 5 shot group ( my cold clean barrel test if you remember) at around an inch and a half at 150. I have no clue why she no like boat tails but I have never owned a ML'er that did. Glad yours likes them.

Edit to add: I've never owned a .45cal ML'er either. Maybe they have a tendency to shoot them better. I have no knowledge base with them since I haven't owned one.
