Have a Bob Lee 40# and a Bob Lee 46#.  Both are 28# recurves.  Using 500 Gamegetters, 20/16's, 20/13's, all with 125 gr in front.  5" fletching.  Why would the 46# bow consistently be about 25-30% more accurate?

One of three things or a combination.

1. The shooter.
2. The equipment itself.
3. The tune.

Sure that didn't help.

Sorry.

The 46er is better tuned = brace, nock point, arrow.

AND/OR...you are getting a cleaner release with the 46er.

That would be my guess.

IMHO...46er probably shoots flatter.

hey tom chk out the thread for "stiff arrow?" theres a very usefull link i think you will appreciate .

I found the lighter the draw the more a poor release shows up, that little extra weight can hide a poor release.

I have a set of 35# limbs and at the bale it makes me work really hard on my release, when I go back to 48# I normally find I'm much more consistent with my overall form. When I have a sloppy release with 48# limbs the miss isn't quite as bad as the 35# limbs.

The higher the Bow weight the bigger the chance of a poor release, the lower the weight the less chance of form mistakes, it's all about balance between control and performance.  

yes zeta ive noticed the same i once had an 83@ 28 , drawing 30" and release was non issue bow arm was more relevant i shoot 60 at 30 and reliece is very much a factor now.

2016 is borderline stiff for 46lbs, definitely stiff for 40lbs; the heavier bow will like those arrows much better.  Try a lighter spine (1916 maybe an 1816) on the lighter bow.

Thanks for the help.  Heard a rumour that there will be a discontinuance of manufacture of the 1916.  Any truth to it?

Don't know, but you can get the .600 spine carbons and play with length and point weight to make a good shooting arrow probably for both those bows.  Paul.
