Ok so new scenario to induce some critical thinking skills. U are at the ol' Walmart's getting some vittles! U get your stuff and come outside, suddenly al'jabar tightpants (Jihad) scoops u up. Ol' Remmy700 is the only redneck with shooting skills in the area that happens to have his tikka with him while taking pics of birds posted 500 meters out on top of the local kohl's (while his wife is shopping). He has a freshly zeroed simmonz pro hunter scope on his new tikka build! What caliber do u hope it's chambered in to save your ---??
