I have a custom Rem 700 300RUM since '99. It started out as a Rem custom shop AK wilderness rifle, and in 09 I had it rebuilt. It's little heavier, but has a fluted 27.5" lilja barrel. I've always shot 200 Accubonds, but yesterday I shot a .3" group with the 208 Amax. I recently put a Bushnell LRHS on it. I will walk as far as any elk hunter I know, and a 9lb rifle goes against the grain of most backpackers, but one thing I know is elk absolutely HATE my rifle choice. This year, will be no different if I don't kill one during archery season first.
Tack driving 208 Amax doing 3100+ .. look out.
