Bruces 410 grain 416cal go to the same point as the 400grain Woodlieghs in my Rigby. I have only shot 1 pig with the Rigby and the Bertrams worked well.

Bruce did tell me he they were not bonded and slightly on the soft side. He would feel comfortable useing them on every thing up to but not including Scrub Bull and Buff.

The 416's weight between 410 and 413 grains but all go to the same point and as Con said they have the heel. Factory crimp dies might work.
