[QUOTE="7mmRHB, post: 559485, member: 3584"] 95, I can give you the case capacities of these three,plus the 6.5 x 47 measured in grains of water with the cases filled to the base of the neck. 6.5x284 = 62 grs. water. ----------- 140s @ 3000 to 3100 fps 260 Rem. = 50 grs water ----------- 140s @ 2850 to 2900 fps 6.5 Creedmore = 47 grs water ---- 140s @ 2825 to 2875 fps 6.5 X 47 Lapua = 44 grs water ---- 140s @ around 2800+ fps The capacity and feet per second are variable depending on bbl length, how each are throated, ( to fit in mag. box or loaded long for a single shot) and how hot they are loaded. So these FPSs are just ballpark numbers. The 130s give you another 100 fps or so. The Creedmore brass is of questionable quality while the other three are available from Lapua or can be made from Lapua brass. ( 260 rem.) This ( Lapua brass ) is always a good thing !! The 284 is best with a long action and the 260 is best with a long throat and extended mag box to get the most out of them. ------- RHB [/QUOTE]
