I used to shoot Axis & ACC for years, but was never happy with the FOC. I've been shooting Black Eagle X-Impact 300's for a few years now at 28"/70#, both with the regular outsert, and the heavier stainless outserts.
With the regular outsert, total weight is 425g & FOC is ~17% with a 125g head, and they fly/group great out to 110 yards. At 280 fps they have shot through bull elk without hardly slowing down, using a 1-3/4" expandable.
I used some 3rd party stainless outserts this year on the X-Impacts to get more weight & FOC, for a trip to Africa. Ended up at 23% FOC at 565g. Never chrono'd it, but pin gaps widened as expected, which is not necessarily a bad thing. Anyways, totally smoked 1 blue wildebeest at less than 20 yards, which was my only bow opportunity. They grouped fantastic at 100 yards during testing, but I think the "sweet spot" (for my setup) lies around the 500g mark, which will still have 20% FOC with 125g heads.
If you're shooting any kind of distance with wind, stick with the 'skinnies' (5mm) and use small 4-fletch. The difference in drift at 50+ yards is significant, and the fletch choice makes a significant difference in drag & drop as well.
And while the 'skinny arrow penetration in animals' thing gets beaten like a bad mule, all I can say is those X-Impacts hardly slow down on chest shots, and that is on big-chested heavy game. For whitetails / sub-50 yard type stuff, the regular outsert / normal weight setup is great.
