Here is the porting of the barrel on my buddy's .378 Weatherby, he says it does make a significant difference in this caliber, as I have only fired the ported version I have nothing to compare it too, but the "legendary" .378 really wasn't that bad, pretty much like my 416 Rem Mag Winchester except the Weatherby twisted more in recoil.

I HAVE seen 3 rifle bbls split from the EDM cuts of Magnaports.
each was a stomper, a .378Wby, a .338/378, and a wildcat .30 built on a .378 case before it became a standard . Have also sen a LAR gRIZZLY IN .45 wiN mAG SPLIT AND LOCK UP THE GUN.

THE 338/378 split the bbl in 2 parallel cracks from both cuts all the way back to the reciever.
Have never heard of problems with standard calibers but with the serious burners problems can happen.
If concerned with recoil, go with a brake.

That is really interesting, Lawcop. I Have never seen that as i don't have a Magnaported gun with that high of a muzzle pressure but I have been around enough metal failure to know that creatiing a radius at the end of a crack willl stop propogation. Same principal behind Novus windshield repair. Maybe Magaporting needs a little radius at the corners of the trapezoid to prevent concentratiion of streeses. Excuse the crappy typing but I am in a hotel room trying to use the TV/wireless internet keyboard crap and would kill for a laptop.

ErikD,
Thanks, I have posted pics before, I'm not sure what I did wrong this time but I'm sure it was something simple!
