Tanoose, can't coment on the new blr's as all I have are older models. But I do have 2 in 358 and I believe for your purpose it is and ideal cartridge. I usually shoot 200gr or 250's but am thinking about trying the 225's as a possible all around bullet. In the 200gr I like the rem core-lock and the 250's I use are hornadyRN.
Factory amo is expensive so you should plan to reload. You can simply run 308 brass through a 358 die and form brass. Regards, Byron
