[QUOTE="Trickymissfit, post: 576095, member: 25383"] interesting. I've been interested in doing a 6.5 and a 30 caliber off similar cases (they'll be headspaced differently for saftey alone). Been thinking about the .257 RCBS or the .257AI necked up to 6.5mm. The 30 caliber chamber would also be similar, but the case length will be slightly shorter with a .33" neck length. The idea is not to be able to mix them up for my own personal saftey. I think I can safley see 2900 fps with a 140 grain bullet in the 6.5, but the real goal in to use longer & heavier bullets. The thirty would have a datum line that's about .070" longer. The goal here is to see 200 fps over the .308 in the 170 thru 190 grain bullet range. Don't know if I will get there, but honestly think that 150 fps is easilly attainable. I need to CAD these rounds out to see where I stand on them, as the 30 caliber idea may not fit in the 57mm case length. gary [/QUOTE]
