I have seen a lot of light fast bullets glance off ribs and turn any which direction. More with the 7 Mag than anything else. If you have never seen major damage done by 30 caliber bullets, then you need to get out more. No matter what caliber you use, bullet selsction and shot placement are by far the most important. A good hit with a good bullet from a 30-30 kills game just as fast as the Superknockerwhizbang magnum or varmit cartridge. Thats from 48 years of shooting deer with about every gun there was in those years. In all those years, nothing killed game any faster than the 6.5x55 swedish mauser. Thats a 140 grain bullet at about 2500 fps. Before somebody thinks that I am knocking the 7 Mag, I am not. I have had five of them. Its just that early on I had a few problems with Ballistic tips at high velocity and close range.
Its true that if someone has had bad expierences with a caliber, in this case the 243, then they won't change their mind unless they prove themseves wrong. Once I used the Nostler Partition in the 243 I found that that combo worked well. All other bullets I have tried have been inconsistant. Sometimes they worked fine on small deer and sometimes they didn't. Therefore I would use it with Nosler partitions and avoid it like a skunk with anything else. If I get tired of the 243 debates I will not click on them.
