Don't have the 3-15x42mm in hand yet, but the specs sure do make it out to be a pig of a scope. Going to mount it to my son's Kimber 8400 Montana .270WSM for giggles. Hell, the 8400 is heavier and the stocks contours and ergo's aren't as svelte as it's 84M brethren, so perhaps the pig scope will balance it out! lol
