with Big. I have used the plain old Winchester 240 gr JSP, and also the winchester 240 gr HSP. On hogs they both ahve penetrated very well, and it seems the little hollow point on the HSP's give a good combination of penetration and expansion in a factory round, but they are not a hollow point bullet in the traditional sense.
I have also used some cheap PMC 240 gr SP and they actually worked pretty well also. I think you mentioned ELK? I would likely opt for a heavier bullet weight for elk though. I don't see the need for expensive custom ammo for whitetail and hogs, but for Elk I would go heavier than 240gr. JMO
