Hi everyone,

I'm planning a build on a Savage target action. I'd like to build basically the fastest 7mm that I can. I know that the short target action is intended for 308-type rounds. I'd replace the bolt head with whatever is needed obviously.

I'm concerned about case length coming back out of the port/the port length being too short.

When the cartridge is loaded it doesn't matter much because the round can basically be "shoehorned" into the chamber. My concern is the length of the brass coming back out and whether it'll fit through the port in the receiver.

Trim length of various cartridges under consideration:
7mm Rem Mag - 2.490"
7mm STW - 2.840"
7mm RUM - 2.840"
28 nosler - 2.590"

Has anyone successfully run a 7mm Rem Mag through a target action? Because if the 7RM works, I think the 28 Nosler would work too. Not sure about the STW and RUM.

Now, practicality of caliber selection aside, is there anything stupid about what I'm proposing?

Thanks in advance!

Dustin
