to be honest the edge and lapua are closely related but yet still two different things at the same time. The edge is based off a 300 Ultra casing and is necked up to 38 caliber. The 300 ultra casing actually comes from the 404 jeffery so this means when the casing is necked up to 38 caliber it has a bigger shoulder and in turn will hold more powder. The edge shoots the 300 grain SMK at around 2800 + FPS out of a 30 inch barrel. Which is faster that a Lapua. The edge rifle in it's self to build is miles cheaper than a Lapua and the reloading almost seems half the cost.
As for overall performance edge verse lapua if you have 3 to 6 thousand dollers to buy the lapua and pay 5+ dollers a round than go for it. But we built our edge off a remington action with a match grade barrel, custom trigger, nice chote stock, DE muzzle brake and a wyatts extended mag box for 1500 dollers and it shoots around .5 MOA and is a little over two dollers a round to shoot.
I am no expert at this by any meens but this is what I know about this gun it's too easy to shoot and dope wind it's almost unfair.
