Nosler Trophy Grade 280 Ackley Improved Review

The 280 Ackley Improved cartridge has been around for quite some time as a Wildcat. Basically it has the same parent case (30/06) as the 270 Win, 25-06 Rem and of course, the 280 Rem.  Ackely Improved means the shoulders are at a 40 degree angle making it hold a few grains more powder than the 280 and thus a little more velocity.   The Ackley Improved rounds are generally thought of by those that like it as being extremely efficient, those that do not dismiss it as unneeded and a pain to deal with for a few extra FPS.  Well, my take is they are both right. What the 280 AI does is get danged close to a 7mm mag in terms of velocity without the use of a belted case and with less powder, i.e., more efficient, similar trajectory with less recoil.  I like a flat shooting rifle having grown up hunting senderos in deep South Texas, the 25-06, 243, 22-250 all were common around our hunting camps.  As I started shooting more long range and really got the benefits of high BC bullets at extended ranges I started looking around at alternative hunting catridges.  7mm bullets have high BCs which translate into flatter shooting (in all honesty more noticable past 400-500 yards) with less wind drift.  The 140g Nosler Accubond is travelling at 3150 FPS out of a 24″ barrel and out to 500 yards is just as flat as a 25-06 with a 100g bullet and with less wind drift, past 500 (more than I personally would hunt) the higher BC 7mm bullets start to really shine, guys are pushing well beyond 1K with 160 grain bullets.
