points for accs

[fazer]

i have some easton acc 3-39s 440 32in i have cut them down to 301/2 in i be told they are now one spine too stiff can i go to 110 or 120 gr points iam useing 100grs at present and were can i get heavy points from

you have been told they are one spine too stiff, so you are thinking you can't shoot these arrows without altering point weight, Oh! they mess with your head these "experts"

Shoot the arrows if they group then the spine is fine, if neccesary chuck some 120grn points in them. ACC's fly very well with heavy points.
Buzz is right, Sometimes these expert can cause more harm than good. If you went by the chart I have been shooting 1 spine to stiff for the last 2 years ( believe me I havent).


I have just had a look at the Eastern computer chart and my personal thoughts are that you are only very slightly stiff. and if there is a isssue with the tune then new points will bring it in know problem.

What draw weight are you shooting? I'm shooting 32.5in ACC 440s at 43.5lb (drawn to 32in) and they fly reasonably straight with 100 or 80 grain points.

The arrows may be stiff for you, but that's far better than too weak. Heavier points won't make a vast difference and will give you poorer sight marks, but as long as you can get them to group acceptably well and fly straight down the range, don't get too tied up in knots with tuning. Just make sure to spend a bit more time choosing the right spine next time you're in the market for arrows.

Good shooting.

That's odd bearing in mind the spine for all Easton arrows is calculated from a 29" shaft by supporting it from two points at 28" and measuring the deflection in inches that results from hanging a 1.94lb weight from the centre.

The only arrows which show the amount they can be trimmed in the 2008 Easton Catalogue are the X10 and the A\C\E which are of course barrelled shafts.

Don't think I get your point Worthipa. He had arrows of x length, presumably a good spine fit. They were then trimmed to y length, and shortening = stiffening. Therefore he may need a heavier point in order to stiffen them. It's not a question of a maximum trim length.

my draw weight is 42.5lb at 31ins did a bare shaft test arrow went 18ins to the left all fletched arrows grouped in the centre of target if i increace the draw weight will it compensate of a stiff arrow e g by 2-4lbs

Can I just highlight the point that your bare shafts GROUPED in the centre of the target.

By itself that doesn't mean much. Set everything straight with a solid button, then do that test at about 10m. *THat* tells you if the spine is right.

no bare shaft went 18 ins left from the centre of target
