No to 50 yds. I'd have to think about 40 yds. 30 or less, no brainer. Just because you can hit a Ø3" circle on a 18" X 18" foam block at 50 yds in your back yard doesn't mean the same applies to any deer (monster buck or not). "String jump" doesn't apply to afoam block (it'll take twice as long or more for your arrow to go 50 yds vs 25 yds, not done the math, just a logical assumtion), plus your heart rate and breathing is not quite as intense when the quarry in made of foam. Thats my opinion, to each his own.
