[QUOTE="MagnumManiac, post: 2204092, member: 10755"] Overbore doesn’t exist. When this term was coined in some gun rag of the 50’s, very slow burning powders were not available, hence the overbore situation arose and was quite true. Nowadays, with powder like RE33, RE25, Retumbo and H1000, there are very few cartridges now where adding more powder of a slower burn does not increase velocity, which is essentially the epitome of said overbore. As to the 6.5-284, I have a barrel blank here that has been profiled and rough chambered for this cartridge but have never done anything with it. It is at an unfinished length of 32” and was made by Bartlein, had it so long now I don’t recall all the specs, other than it’s a 7.5” twist and this was the reason I didn’t use it. I see less and less 6.5-284’s on the firing line these days, people are going to smaller cases. Cheers. [/QUOTE]
