AGW,

I also have found the 90 grain Sierra to be a very tough hollow-point. I have shot it quite a bit in my custom .250 Savage at about 3050 fps. At this velocity, it does not expand quickly enough to be a viable varmint bullet, but it makes a really good load for pronghorns - I have killed several with this bullet loaded in this cartridge.

Thanks again for your very useful information,

M. Bell
