How many lbs per full turn on a screw

[Stéphane]

Man this title sucks.

I'll try to explain it better. I have 2010 Bengal with 70lbs limbs. When I left the pro shop today, it was set at 60lbs. Now I did one full turn (increasing) on each bolt. What could it be at? Any rule of thumbs applying here?

I calculated the arrow speed using online calculator and I would go from 260 to 270 (appr). Every bit counts, right? Hunting season is so close and I'm too excited to sleep!!!

Rule of thumb? Approx 3 -4 lbs per turn. How many turns until it bottoms?

[Stéphane]

I don't know. Maybe 3 more?

It is 3lbs to a full turn. 5 turns equaling 15lbs. At bottom if you have a 70lb bow it should read some where from 70 to 72 lbs if 60lbs the same thing 60 to 62 lbs

Turn both limb bolts in all the way. Put a mark on both limb bolts. Back them out equally 3 turns each. That will take it down 9 pounds if you want more then 1/2 turn each.

Not really. Speed isn't everything especially for hunting. Your much better off shooting at a comfortable draw weight, with hunting usually you don't shoot warmed up so going too heavy will drop your accuracy. Bows today have enough speed even at 50# to kill most things.

Now does this rule of thumb only stand for Martin bows, or is that any bow in general?

Martins for sure. But I though their are a few other companies that do. Maybe some one else can give more insight. Since all I have ever owned is martin.

Most bows in general but some gain a little more depending on the design and setup.

I will have to test it out and see what I come up with. Give a few turns to the bolts and measure the dw with my scale. Cool, thanks for the info!
