Detachable magazine/bottom metal for Sendero

[Speedygoss]

What is the best way to go if I wanted to switch out the bottom metal on my Sendero .338 RUM to a magazine.

Thanks,
Speedy.

I am using atlasworks bottom metal on my sendero. I have a rum mag for it, seekins would be another route to consider they have long and real long.

What is the best way to go if I wanted to switch out the bottom metal on my Sendero .338 RUM to a magazine.

Do You gain or loose any C.O.A.L. length going this route?
