I think that’s comparing apples to cannonballs. Wouldn’t it be closer to say that, a .308 with a 26″ could perform the same as a .30-06 with a 20″ barrel, using the same bullet?

A 50@30.5″ is definitely faster than a 50@28″, assuming the same weight arrow. How much faster? 20fps? I don’t know.

The 28″ draw would need an increase in poundage to offset the fps difference. How much more?

That’s my question.

I read somewhere that Dan Quillian said an inch of draw length is equivalent to 10 pounds of draw weight. I’m not that optimistic. So what is it?

Ok, that’s what I was thinking.

I think you’re missing my question. What would the poundage need to be at 28″ to be the equivalent of a bow pulling 50@30.5″?

If we both wanted to shoot a 500 grain arrow (not necessarily the exact same arrow, mind you), what would poundage would he need to shoot to match the speed of my 50@30.5? 55 pounds? 60 pounds?

Again, this is a theoretical, not a practical exercise.

This is more of a theoretical exercise. We were trying to figure out the advantage of a longer draw. Since I pull 30.5″ with my Hill, and he only pulls 28″, what pound would he need to pull to shoot the same weight arrow at the same speed as me.

Or, a bow pulling 50@30.5″ equals ?@28″.

Or, if he shot my arrow out of his bow, how many fps would he lose over mine?

Or, if I only pull my bow to 28″, what would be the fps loss?

BTW, we’re not actually basing any purchase, arrow choice, tuning, or anything on this. It’s just a mental exercise. I don’t have a chrono, or I could figure it out quite easily.
