X10 Tungsten vs Stainless Steel points.

[timfatheroftom]

OB,
you might find that stainless point being longer in shank length,will stiffen the shaft for the same point wt, as well as giving a shorter shaft for the same overall length, therby also stiffening shaft( and a few gns. saved in wt), however the 120 pt wt is a bonus if shooting long heavier shafts to maintain FOC, just my opinion without any scientific training in any subject whatsoever!

hope this helps,

It will be the consensus.

BUT the REAL question is not "which is the best" point - it is "am I willing to spend £140 on points when I could spend £14"....

For little difference.

But the tungstens are better.

INCORRECT, again. THE REal quEStion is to be found at the start of the thread. Please EXcuse. I struggle with CAPS lock also

I now think it is time for me to lie down in a darkened room...where the only sound I hear is that of silence.

with tungstens you may need 1/2" more shaft length, and hence MAY need a stiffer spine. This might add ~20grn to the shaft weight.

Furthermore, increased FOC with a more dense point decreases gliding effct of arrow; may see a TINY TINY drop on the target (ie. worse sightmarks).

Two reasons why tungstens might be a problem for sightmarks.
If you pull a decent weight (46#+) you wont need to worry (but then, you already knew that).

QUOTES SUCH AS "tungsten pts are ass kickers" is complete nonsense!

they work, when they work best for the archers setup, please dont tell me that Hyun Sun Park( from you know where!), probably the best, most consistant archer in the world, possibly ever, deliberatly handicaps herself by not using them- as she does not!

there are pros and cons for all items of archery equipment, tungsten pts, just like the arrows they fit into, will not gaurentee an increment in points scored , I am not talking down to anybody here , its just an observation, flame me for it if you choose, but then do i really give a .....................

[timfatheroftom]

by not having to shoot 90mts,you are by that statement infering that she is using 90gn pts or else she would still be able to use tungsten pts with all your stated advantages ie FOC for wind drift, ass kicking abilities etc. would she not?

and as she is probably drawing well over 44lbs on her fingers with a relatively short draw (around 27") ,

and on that note, I'm gone from this thread before it starts to go round in circles and dissapears up its own.......

The stainless points are also very long.

I much prefer the tungsten points, but thats a personal choice.

Oh, and the 10 grain difference wont affect sight mark on an X10, its too heavy for that. It wont affect a bareshaft test either - 10 grains is tiny.

PS: and shooting the poundage you probably are, you probably dont want to have less than 110 gn anyway.

you would be surprised at what a 10 grain difference makes, I tested two sets of X10's each with 10 grain difference in point weight, all other aspects were the same (length,fletch.pin nock)there was on average a 12 foot per second difference between the two sets. shooting out of an Apex 7 set at 58llb

Thats a VERY small percentage of the arrow weight, yet 12fps is a much larger percentage of the original arrow speed - the two do not correlate, and i think you may be the only person to make that claim.

Maybe im missing something. To me it seems they correlate remarkably well;
~320fps bow, 12fps difference
~350grn arrow, 10grn difference

Add in the fact that the relation between speed and mass is reciprocal and fairly non-linear. I could believe you could get that speed difference from 10grn change.

With regard to Park SungHyun. I dont think we can say anyone is even probably the most consistent archer ever. I can think of afew male archers who get the same scores or higher.
We dont know anything about her draw-weight/length, and Sam has a point (pun intended!); that perhaps the most important distinction between tungsten & SS is the availiablity, or not, of 120grn. Very important for male archers (shooting 90m with ~50# on fingers)

[ASW1973]

she is shooting 120 grain stainless steel points made specially for koreans and some select others and not for sale over here all world class archers select an arrow in this order: point weight (heaviest possible) spine to tune point weight (slightly stiff), poundage adjustment to tune arrow. No one shoots a sub maximum point weight unless a sub 40lbs holding weight female recurve or sub 46lbs gent and there aint many of them around at this level.
so the answer to why tungsten: pureley point weight, any protection to the shaft is secondary, the foc is better with dense material so a perceived bonus
OB when u get a set of x10's bare in mind that a set of 28.5 (nothing out the back) X10 450's with tungsten 120grain points was right on the limit of tune (shade wippy) out of a 47lbs on fingers set up I was working with today so start in the 430 bracket and appreciate it wont be quick but it will be massiveley more consistant than the 520 spine aces you have been using

A friend told me the average poundage of female international archers is around 32#. I was surprised it could be so low. Are you saying this was mis-informed?

(i recall that female archers in both my clubs get to 80yrd reasonably well with 28 to 32#)

BTW, you say max possible point weight. Would you advocate 120grn for an archer pulling 30# at 27"?? Seems excessive since FOC is already well over 20%.
