[QUOTE="ntsqd, post: 1704970, member: 93138"] Just for discussion's sake let's say I/we wanted to duplicate 7-08 performance in the 140gr. - 150gr. bullet range, in a .25 or 6.5 mm bore. That is to say same bullet weight(s) at the same velocity(ies). I'm assuming that such a heavy in .25 could be found and included it so as to not reject it w/o due consideration. I'm thinking that the slightly smaller bore at the same bullet mass will force an even better BC, which I expect to translate into less wind drift. Our range is notorious for a L-R cross wind of varying strength. The targets are steel and they have to be knocked off their stand. A 140gr. 7-08 is reportedly just about minimum to do this at the max distance of our local range (~600yds), [B]IF[/B] the shooter does his/her part. Shooter is moderately recoil sensitive and weighs 110 lbs. max, so the 6.5/.378 Wby is not a contender for consideration. :) A cursory glance at loads for the wunderkind 6.5 shows it's a little slow in comparison. What is real world? What other .25 or 6.5 calibers should I be looking at? Would prefer to stay in a short action if possible. Don't really need to surpass the 7-08 performance, merely equal it in a smaller bore and with the same bullet mass. [/QUOTE]
