Yeah,I know it won't fit in a Remington 700,.532" vs. .590". But,damn it'll be something very different.

And Quality Cartridge even makes the brass. You will have to wait for it though,not exactly a bunch of .338-378 K.T.'s out there.



First off the rim size is the same as a 338 Lapua and I have a 338 Lapua built on a 700 action. The case capacity is close to the same. I also have seen 30/378' built on a 700 action. [/quote

338-378 is a recipe for disaster in a 700. Seen action stretch and bolts come apart on that combo


Only if over loaded and or built incorrectly. I've seem the full length 338/378 work just fine in a 700 action.

When Rem marketed the M-700 in 338 Lapua they tested to 100,000 psi. But people overload wildcats and shoot a lot of ammo through them and then blame the action.

The Rum and Lapua duplicated 338/378 Kt ballistics in available cases.



I seen alot of 700 action with streched received and bolts locked up due to blown primers. There not enough meat on the bolt head after opening it up to .580, or .588 for the LM. I used BAT action for my 338-378 nd 338 Lapua mag
