Remington 700 action question.

[Buster95]

A Remington 700 long action (300 win mag) and a ultra mag action (300 RUM) are exactly the same no extra machining on the RUM? Only the magazine box is different?

I think the bolt face is slightly bigger on the rum, but I could be wrong, length wise they are the same

Same action, slightly different mag box.

Basically the same action but I thought the Ultra Mag rails were machined larger... and a weird box is used.

The bolt is the same.

The space between the rails is greater on the RUM receiver. Remington's attempt to use the same width for the box and simply cut windows in it was and is stupid. Widening the mag box and the receiver mortise (by about forty thou) makes for a much better functioning magazine. The follower has to altered as well. This is what Remington should have done in the first place.
