Simple … the faster you go the flatter your arrow flies. The fastest bow that fits your budget and buying philosophy is the one to get. They're all reliable.
Blacktail, exactly why I went to a single red dot. Less clutter. This approach may not appeal to all but for this guy I like the simplicity of this approach. Scope Clutter and eye relief with crossbow scopes are a challenge for me.Flat trajectory you will not get in slower fps crossbows ! So lets take my older slow wide limbed recurve, its 2 3/4" high at 20 yds. Its dead on at 30 yds & its 3 1/2" low at at 40 yds. I use a one dot red dot, i hold under n over never have trouble with clutter using it. It also has plenty to do with your arrow weight
I have a UTG red T dot that i like very well. I can put it on one of my faster models n reach 60 yds, it has a leg joint dropped that fits on the right on at that distanceBlacktail, exactly why I went to a single red dot. Less clutter. This approach may not appeal to all but for this guy I like the simplicity of this approach. Scope Clutter and eye relief with crossbow scopes are a challenge for me.
FYI: With practice you can be quite accurate at longer distances with non magnified scopes. Practice, practice, practice. Also, I have similar experience with hold overs when I shoot 400 grain plus arrows shooting Xbows that top out around 385fps (Barnett TS-390 Xbow).
Oh, we are now... LOL.... As with all things on this forum there are twist and turns with all OP's. Come-on now. You have a point but that point is never a straight line on this forum.You guys … are answering a determinate equipment or physics question that has a fixed solution with inserting a variable that isn't part of the question. That "variable" is the talent, skill and training of the shooter. The guy didn't ask if he should practice more with his slow bow; he asked if $250.00 for a 100fps increase to a fast 415fps bow is worth it. He doesn't want to "guess" at distance to target, which of course is a prerequisite that increases as speed decreases. Basically the guessing is inversely proportional to the speed. You're over-complicating a simple problem. 415fps = less guessing than 315fps. Soooo, the clear answer is: "yes, he should buy the 415fps crossbow."
