I have never owned an Ackley Improved cartridge and dont foresee that I ever will,shot placement is the ticket not another couple hundred feet per second,the 7x57 is a top notch round anywhere you put it,Ivory Hunter Mr. Bell killed over a thousand elephants all with the 7x57 and FMJ bullets,I think its a lil tuff too improve upon a cartridge that is this good..........

broken bones broken heart stripped down an torn apart a lil rust but Im still runnin countin miles countin tears twisted roads and shiftin gears year after year its all or nothin Im not home and Im not lost just holdin on 2 what I got...God and Guns
