45# ACS CX

[bkbk12]

I finally broke down and bought a ACS CX 45# 66" at 28" and I draw closer to 28.5 so 46-47 pounds I was just wondering what arrows everyone is shooting with a similar a weight ACS I am guessing around a 30" .500 spine with 175-200 up front also are you building out your side plate any help is appreciated.

I think your looking more at a .300 spine at that length with 200 up front.  The ACX is a very high performance bow.

I shoot the same bow, I draw it over 29"... I use both 500 Beeman/Axis shafts or 400.. With the 500's I can go up to 200 up front on a 31" shaft. With the 400's can go up to 300grains up front if I wish..

 Yes, use sideplate width to tune with, anywhere from .100 to .200+ depending on your arrow setup...

Fantastic bow !!!!

If you can get your hands on a CX Heritage 150, try it with a 175 fp at 29 -29.5. I am drawing a similar weight and put in a 50 insert and 145 grain head and they fly nice. From what I can see these bows really shine with a heavy arrow, it just seems to ring out the performance in these limbs. Enjoy they are nice.

I built out the side plates on CX's for a while; but wasn't really happy with the result over time, and just went stiffer instead. I only shoot wood-75/80 would be about right for your set up.

I would say a .500 spine as well. 3 rivers has three arrow test spine packs that I would strongly suggest you start with.

I just ordered a 66in 45@30 and i plan on shooting full length Heritage 150's.

Grizzly Stik Alaskans cut to 30.25" shoot very nice out of my 49# A&H 62" takedown.

First let me explain I have a sickness and love ACS limbed bows. I've got one of O.L. Adcock's early ACS 62" 56@28 one piece bows for hunting and then picked up and a A&H 62" 44@28 three piece for 3D target shooting so I could shoot all day. I shoot the lighter bow year around and then late summer work back up to my hunting bow. My shoulder will not take the year around beating.

That said, I can shoot both of the Beeman MFX 500 & 400s out of my Hunting bow and the 500s out of the target bow. The 500s can be bare shafted with anything from 125 grains up front to 225 and they shoot like darts with out fletching with the target bow. With the 225 heads = apx. 580 grains and 480 with 125 heads, either is plenty to get a pass through with a ACS bow.  

Two weeks before last years hunting season I pulled out some bare shafts of both 400 and 500s and found that the 500's no longer bare shafted like darts out of my heavier hunting bow, weird, I still don't know what in my shooting style or release changed, but I had slightly lengthened my arrows by 1" because I draw my lighter bow slightly farther, that seems to be enough to make the 500 no longer fly like darts with the heavier heads and bare shafting.

So after hunting season I played around with the 400's and found the right set up for my hunting bow with the 225 up front. Apx. 620 grains was the ticket.

Now the problem is that I shot the new three piece ACS with 66" 48@28 limbs and Carbon Riser!

You may wish to experiment with Stu's calculator. My ACS set-up was extremley close. Using AD trad lites, the program stated my arrow was 0.5#'s heavy and my large snuffers showed stiff. I added six twist to the string and I was there.

Field point,bare shafts, and arrows tipped with large snuffers would group tightly at 20 yards.

Note: Had similar results using MFX 500 arrows for a BW.

Even though my experience with Stu's calculator has been great, there are others that have not enjoyed the same results.
