Pull them, for sure. The effort will be well worth it when both hands are still intact. 2400 at that level a load with that weight bullet sounds pretty unpredictable to me. I cast the 429421, load and shoot that same powder through my rugers and I'd never consider shooting 26 gr's, or letting anyone near me shoot it. Pulling bullets is a total PITA but ALWAYS worth the effort-at least in the peace of mind dept.
