I decided, after much thought, that it would be impractical to rechamber my existing 35 WAI barrel to the 358 NM. it would end up just too light...I've done that before and it is a pain! so I had my smith order me a Shilen CM #4 contour 35 cal with a 1 in 14" twist. I'll have him finish it at 24" and try it before I have it ported or braked. I really am not recoil sensitive, especially after my eye doctor told me not to worry about the recoil hurting my repaired retina in my non shooting eye. I feel much better about this route, even though I'll probably end up with 180 to 225 gr bullets ( Barnes TTSX). I like having the option of heavy bullets ( especially that 310 Woodleigh!) Thanks for all the help guys, you have probably helped to "save" my one good eye! ha.
