i tried a search, but too short. so i'll ask here. i have a remmy .243 hb, that has been a long time friend. (22 years) but i am thinking of doing a 6.5 wsm on it. where, oh, where, can i find info on this ? i would like to launch 140 gr. bullets, but what should i expect from this wsm variant ? .264 mag velocities ? am i barking up the wrong tree, and just stick to a .260 so no mods have to be made to my remmy sa ?? i really do like the .260, but out here in the wild west, bigger is always better to some extent. any info would be greatly appreciated.
