7mm RUM Controlled feed?

[jrhammo08sxt]

Guess I need to brush up on my Savage 111 knowledge. I just picked up a large shank, stagger feed Savage 111 in 7mm Rem Ultra Mag. The bolt is a control feed, which was to my delight as I did not know Savage made those at on time:heh:, also, the stock has metal pillars in the Tupperware stock?? Something I guess I didn't know either. All good stuff though. Turns out that I got a heck of a deal on the gunbroker... Anyway, I would like to do a conversion to a 300 RUM. I already have a brand-new stainless 300 RUM Barrel, lug and nut (large shank as well). As far as I can tell from the research, 7mm RUM and 300 RUM have the same size boltface and about the same COAL. Is there anything that I would need to do besides a barrel swap? I'm sort of amazed that it is this easy. I usually end up having to change a few other things out...

Oh, and just to answer the question, "why would I want to change to the .300 RUM?" answer= I already own a 30-30, 7.62x54R, 7.62x39, (2) .308, 30-06 and a 300 Win Mag. So, I want to keep it in the 30 caliber family. This will round out my collection nicely!

Good idea to keep it in the 30 cal

I am curious also, what is the Hx for savage and control feed...

[jrhammo08sxt]

Awesome. Just what I wanted to hear. I don't know what you mean by Hx...but the serial # starts with G046xxx

[Stockrex]

sorry, Hx = history,

anyone can educate us when went to control feed?

This is what I found online, no date though:

UltraMag and WSM Rifles
Savage changed the bolt heads on these calibers to a controlled feed system.The bolt heads have been modified to allow the cartridge to slide under the extractor. The ejector in these models is in the reciever instead of the bolt face.These changes allow reliable feeding of these larger cartridges.
Barrel Shank Sizes
The shank diameter on Savage's standard calibers is 1.055"The Savage rifles chambered in Remington Ultra Mag and Winchester Short Magnum have a larger shank diameter. These measure 1.120"The outside of the barrel nut is the same diameter on both the standard calibers and the Ultra Mag - WSM calibers.All barrels are threaded 20 threads per inch.Note: Some of the first Ultra Mag and WSM rifles were made with the smaller diameter shank. The larger diameter shank barrels will have a step in front of the barrel nut.
