[QUOTE="Fiftydriver, post: 132649, member: 10"] Blygy, Your really splitting hairs here. The 6.5-300 will have an edge performance wise but not by a drastic amount. If you look at the best bullets in each caliber, its pretty close to a dead heat as well. Comparing a 156 gr ULD RBBT 25 cal wildcat Bullet to the best 6.5mm bullets made by the commercial companies is not really a comparision. The big Wildcat will get you BCs in the .8 range. In my 257 AM I use .82 to get my ballistic program to match up to actual bullet flight. That said, I just got some new 168 gr ULD RBBT 6.5mm Wildcat Bullets that look extremely impressive. These were made with a die that will not be used on the production bullets and as such the production bullets will have a higher BC rating which should be slightly higher then the 156 gr 25 cal bullet. These are the heavies of the heavies though. The 6.5mm family has several very good quality 140-142 gr class bullets. The 25 cal only has one bullet in this range in the 142 gr ULD RBBT but its a hell of a bullet. So the 6.5mm does have an advantage on selection but as far as the best bullets out there, the 25 cal has bullets that will top any conventional 6.5mm bullet until you get into the real heavy custom bullets. I will be testing the new 168 gr ULD RBBT in a Lilja 1-8, 3 groove chambered in 6.5-284. If this rifle stabilizes these bullets, anything of this size or larger will with this twist. We will see. TO be honest, I would probably opt for the 6.5-300 just because I am not a Wby fan but it has nothing to do with bullet selection to be honest or really performance. Kirby Allen(50) [/QUOTE]
