Beiter Nocks. Do they shrink when it is cold(er)?

[King Custard]

Not keeping a diary. i have only recent memory to report- but yes on two cooler days rememberI had probs with my x10 in/outs coming loose from the shafts by a mm or two - and some new nocks just dont fit like the others -which is kinda where you are!

It took so long to get my bieter nock point right though that I just decided to pinch all my nocks with pliers to ensure a tight fit, rather than look for any alternative- hasn't happenned since and Im back to being well impressed with them!
well, when I can shoot the buggers !

No - its the world and your surroundings changing, how dare you question beiter.

serioulsy - like others have said i have had some issues about fitting in arrows (could be chicken or egg though - which is inconsistent - arrow, nock , or both??)

never had differences with strings though

[Erika]

How cold are we talking?

I remember when carbon arrows first came out and we had our state indoor in a cow shed (because that was what we had in those days). It was so cold that the arrows were shattering.

We don't have snow though.

Interesting replies and following one of them, today put three Beiters on the window shelf and three in the fridge (not the freezer). Could hardly get the ones of the window shelf into the shaft but the ones from the fridge fell in. Well I'll be damned. I never thought of testing them that way.
As this confirms my concerns, if the whole nock shrinks when cold, then logically the jaws of the nock will shrink also and hence be a much tighter fit on the string. There is a huge issue with just how tight should a nock be, or for that matter how loose? To have it possibly change from one day to the next or even God forbid during a shoot, cold wind gets up/sun comes out, could give rise to erratic grouping or non grouping.
I have just come in from shooting and sure enough I now know I was not imagining it, because when I put my arrows on the string (large jaw) they were so much looser than on thursday, so much so that the small jaw fitted better! So I changed them over. Thursday saw a calm but cool evening and the large jaw clipped on just right..today in the hot sun, so loose I was worried about a dry fire. I'm sorry, but tomorrow the Easton nock get tried out. Whilst the Beiter is superbly engineered, I can't be doing with a nock that would appear/could/possibly/maybe/might/probably/ change jaw size when I shoot it over a period of archery time.

I can't say that I've ever noticed any difference with my beiter nocks... but then they are purple

OB - just out of interest, have you contacted beiter to ask their opinion??

[Alandee]

OB, have you tried the temperature test with other manufacturers nocks?

[Old Bloke]

Alandee, I will do the temp test tomorrow just to see what happens. Never done much with Easton *G* nocks so I will be interested to see what happens. Always trusted Beiter. Not sure if I have any new *G* nocks either. I was wondering if it was the string changing but the fridge test elliminated the string.

[King Custard]

me wonders if bieter know all about this - and pre-empted this outcry by introducing the bieter nock points - I wonder if they change with temperature inline with the nocks?
More tests OB?

[Old Bloke]

I would have thought that the Beiter Nock Points were a natural progression considering the inventiveness of Werner and his team. Funily enough I have just spent the last hour rumaging around all the bits and bobs one collects and hey presto, a Beiter Nock point, half green half black! I'll try and put it onto a spare string and see what it feels like to put a nock on. Try it from there. I would much prefer to shoot Beiter, but if a problem does exist and is inherent in the make of plastic......

[elastoplastscavenger]

over such a small temperature range on such small parts i would say it is almost cetainly not an expansion issue.

the flexibility of many plastics changes dramatically with temperature and this is more likely the culprit...although i would have expected the cold ones would be less flexible and hence grip tighter/be harder to clip on.
