Arrow charts and decisions

[Cougar Mag]

Possibly investing in some ACC shafts, looking at Easton's chart I can go either way....3/49 or 3/60. Generally the 3/49 seems like the best of the two for my draw length, arrow length, draw weight, cam, etc., but I like a little heavier weight. Thats where the 3/60 comes in. Will the stiffer 3/60 cause tuning problems? My hunting draw weight is 63-65 lbs., draw length is 29.5", arrow length is 28.5" and shooting a Martin Fusion one cam which qualifies as a hard cam. Most likely will be using 4" vanes or 5" feathers and 100 grain fixed blade broadheads. Those of you with ACC experience have suggestions?

Coug,

My experience shooting ACCs is relatively limited. However, speaking from experience with arrows and single cam bows in general I would normally suggest going with the stiffer spine as they tend to tune easier for most folks out of those style of bows. The 3-49 might work as well especially with feathers but I would probably go the 3-60 route first.

I am sure Jeff or Arthur can help more in this area.

Iam pulling 75 lb 29" draw and use the 3-49 shafts for 3D but my point weight is only 65 grains any thing heavier would underspine the arrow.
for hunting situations I strongly suggest you use the stiffer spined shaft like the 3-60.

however If I were to use the 3-49 for hunting I would use the blazer vanes and a Wasp 75 grain head and back my poundage down a little this would be a good set up for 55 to 65 Lb bows.

Going by your specs, the 3-49's are right on the edge of their spine range. You wouldn't have any problems bumping up to 3-60. Might even be better off to do so, especially for broadheads. For me, broadheads tune a bit easier on stiffer shafts.

Don't use 5" feathers on ACC's. You're begging for clearance problems if you do and, after shooting ACC's off my recurve and longbow, I've found you just don't need that much feather for a small diameter arrow. 4" feathers will stabilize a broadhead just fine on ACC's.

In fact, since feathers generally have the stabilizing power of vanes that are an inch longer, you might try fletching some up with 3" feathers and giving them a try. Compare how they shoot your 100 gn broadheads to some arrows fletched with 4" vanes.

Coug,

Questions for you

What spine arrows are you currently shooting out of the bow?

Which type of fletching do you want to shoot?
