The plain Jane 240 grain soft points will do the job on any 250 lb hog I have ever run across.
I have shot more than a few of that size, probably at least 10 or 12, with that type of factory load in my B92, and never required a second shot yet.
I have also used heavier handloaded soft point bullets with equal success.
I cannot say the same for the performance of the hollow point iterations. They seem to work well on the lighter piggies, but dont have the penetration I prefer on the larger ones.
I looked at some Buffalo Bore Heavy 44 ammo once,but there was a note from the owner of Buffalo Bore listing suitable firearms in which to use it.
No lever actions were on the list.
