Thread: .270 muzzle speed

I got nosler .270 130 gram ammo.
Bc 0.435
Muzzle velocity 3050 fps (nosler website)

From 100 meter to 300 meter it drops about 455 mm. (15x0.1mil clicks on my Bushnell elite tactical scope). Grooping was good

Going back to my computer no way this adds up. I have to get the speed back to below 2700 feet to make it work to the real world. Is this Normal?
