What ammo shoots well from another rifle does not necessarily work for yours. As others already noted, either one of your choices will work if they group well for your intended range/purpose. Last weekend, I was helping a couple of buddies sight their rifles. Rifles are identical (TC Venture in .300 WM) and both were using the same factory ammo (even the lot#s) but was getting different results.

Before reloading, the Corelokts was my go to ammo and have harvested many games. My son's .30-06 (Remington 1903 sporterized) shoots the 150 and 180 very well but the 180 keeps a tighter group.

Good luck and happy safe shooting/hunting.
