Atlas, just like past years every model has an advertised "Speed Range" if the bow doesn't shoot within that range then it does not ship.
There's approx an 8fps range so the Equalizer's range at max specs is 294-302fps.
Everyone is latching onto the highest possible number in that range which is 302.
A shipped bow might actually make 302 at 26.5" /60#/ 300gr arrow, but it is also within specs if one ships at 296fps. Most fall around the middle of the advertised speed range, so 298 is realistic for most bows out the door.

So no it's not going to shoot 275-280 at those specs, it will if you trying to shoot say a 375gr arrow rather than a 300gr. Remember 5grs of arrow weight per lb of draw weight to get that 294-302 range.
If you go up in arrow weight, or add additional weight to the string (peep etc) above and beyond what the hush kit, brass nockset and elim. buttons weight your speed will go down accordingly.

A shipped, the max spec Equalizer (26.5"/60#/300gr) will shoot 292 and up to 302 depending upon the individual bow.
