Definitely a 7x57. I watched him review and shoot the rifle on his RSO channel. Maybe falling block takes more pressure than a bolt rifle.I reload and shoot a 7mm08. Ballistic twin to the 7x57 for comparisons sake. 3000fps is the ceiling for the 130gr bullets. If you go to Ron's YouTube and watch him sighting this rifle in, he is saying 3200 fps. That is why I said it's kinda hot for a 7x57. Could it possibly be a 280 / 280AI?
