I have a 52" 1972 Bear Kodiak Magnum 45#... I had it strung today to shoot and while it was laying against wall I noticed the top limb was a lil twisted.

A quick twist of the limb after re stringing and it looked ok.

Now for the question... Is this a common occurance bc of age of bow?... I never leave it strung except when shooting or hunting and always use bow stringer?

Dave:

Things like this happen quite often regardless of the bow or age. The first thing I do when I string my bow is check the limbs. Most guys never do.

You correctly fixed the issue.

I don't have any expertise as to whether or not this is common on older bows....but, I was going to mention that I took a friend's old Kodiak Mag that had a twisted limb.  I twisted the limb back in place, and then left it strung with a slightly higher brace height than normal. That seemed to get rid of the twist for good.  I now leave it strung all the time.

You can bump the limb back strung or not and it usually responds.
Leaving it strung does not seem to affect a glass laminated bow at all.

I leave mine strung all the time. Stringing is when you get a twist!

nope not really common for any bow to twist while shooting it.However it can happen from time to time but as mentioned more often they get twisted during the stringing and or unstringing bd

It's pretty common in older bows because of the stringing habits of archers back then. Most used the push/pull method of stringing and others even used the step through method... bowstringers were pretty uncommon.
That's what caused most of the limb twists you see in older bows... and is a good bit of advice.
