my wife said she would let me fiddle with her 243 and I was thinking about having one of these built along with my other project guns. wandering if anyone has one.

i have a 6mm off of the 7mmrsum case if thats what you mean. about the same cap as a 240 gibbs,6mm catbird, or 6-06 imp. 73 grains h20 cap on a fired case.

what kind of velocities are you getting, and how long is your barrel. have you taken any game with it.

26" re25 87 v-max 3700fps, 28" retumbo 95 berger vld 3530fps, 26" re25 105 a-max 3300fps but did't try to work up this load any further. was just getting in the ballpark for the 28" barrel which has a 1-9 twist. the 26" is a 1-10 and originaly planned for fire forming and woking up loads to save the 28" krieger. i plan on getting some coyotes if they will cooperate and using the 95 berger for now. hit one so far at around 300 but he got away.
