Robert,

Please ask your "experts" to provide an explanation as to why a M1895 Winchester cannot handle a 55000 psi load with the 405 Winchester, but can handle a 62000 psi load just fine in 270 Winchester?

The thrust forces:

405 Winchester at:
55000 psi chamber pressure - 6570 pounds
62000 psi chamber pressure - 7407 pounds

270 Winchester at:
62000 psi chamber pressure - 7909 pounds

Looks like the 270 Winchester hands down beats the 405 Winchester in bolt thrust.

Simple really, the 270 Winchester has a base diameter of 0.473" compared to the 405 Winchester's 0.462".

Come on Robert, what are these so-called "experts" creditials, other than the desire to sell you a Encore/Contender barrel?

The physics, field experience of past production rifles, the manufacturers continued production, and my own experiences with the M1895 completely contradict your comments.

By the way, what are your creditials to qualify you as an expert on the structural integrity of a firearm action?

Not trolling gentlemen, I am sincerely interested in understanding the creditials of the individuals who are making these statements on the structural integrity of firearms.

Scott
