Dan Lilja is an engineer and wrote his educated opinion in his website long before remington decided to try it.
Dan'a article also stated the following about the 700 Action being used for the Lapua sized cases.
"But someone wanting to use a Remington could argue that the Weatherby MK 5 action has the same barrel thread size as the Remington".
How many decades has a Mark V action been used for these sizes cases? Also the fact that there are a lot of 700's chambered in 338 Lapua as well as 30-378, 338-378, etc. that are performing without problems as well as the fact that Remington also chambers the 700 in 338 Lapua should be proof enough that the 700 works just fine, no matter how much OPION to the contrary.
According to Bounty Hunter remington has tested the 700 action chambered in 338 Lapua to 100,000 PSI with out a failure, seems to me that is alomost 36,000 PSI ove CIP pressure spec for the cartridge and should put the nay sayers to rest.
range it,check the wind, dial in correction, aim and only one shot
