some have indicated they rapidly lose accuracy once you go further out. Given how long they are compared to a lead projectile, I wonder if there is enough room in a 45 Colt case to load them up to a high velocity.
I had acceptable accuracy (2" group) at 50 yards with the 454 and a light load of H110 (from the reloading library on the site when the pistol was scoped). As for space, I don't remember the details, but I think I ran out of pressure before I ran out of space and really liked the idea of keeping all my fingers.
