Well, those Trashcans shot well enough for their first time in that rifle but they were punishing. 70 grains of Swiss 3F behind a 497 grain conical was pretty punishing but I don't think they caused those cracks.
That's after only 5 BullShop 460 grainers and 3 of Bat's Trashcan's over that powder charge. Not a great combo for the Accura.

The Apex handles the same loads with ease though.
