[QUOTE="Welderboy11972, post: 2585228, member: 91394"] To me, there's more factors that go into determining barrel throat erosion. Barrel material and barrel shank dimensions are hardly ever talked about. Let's not forget that the barrel also acts as a heat sink. So how well the barrel can shed heat will play a factor in throat erosion to. That was something that I thought about when I built my first custom rifle. 300rum are known to be throat burners. I added alittle extra to the barrel shank when I ordered my stainless barrel. That rifle was my learning rifle. It now has over 2600 rounds through it and it does show some fire cracking for about the first 3 to 4 inches. All the lands are still there and my jump hasn't changed. I shoot 210s vlds with retumbo. And they are moving at a pretty good speed. With that being said. To me barrel material and shank dimension just as much to do with this as being an overbore cartridge. I don't have alot of experience with other different cartridges. So I'm just giving my experience on what I have seen. [/QUOTE]
