I have a 700 bdl its an oldie and it is different to reload for than any other rifle I have. I have tried a ton of bullets though it, and the 100 gr. hornady interlock with mag pro (heavy) and 60 gr. sierra hpbt with varget (really light) are what it likes. In my other rifles they seem to find one weight or at least they like heavy or light bullets, this .243 likes the extemes which doesn't make much sense. either way it is one of the most accurate guns I own next to my favorite savage of course.
