Re-chambering a Ruger #1

Hi all,
Can anyone tell me if the #1 Ruger in .300 Win Mag can be re-chambered to .300 Rem Ultra Mag? Who would you reccomend?
Thanks, Mike

OP, if you find your right smith for the job, please PM me, my youngest son has a '69 No.1B in 22-250 that he'd like to rechamber or rebarrel to something else, not sure what. he's open to ideas. A couple of his thought's were 257 Wby or 260 Rem.
 
The beauty of the Ruger #1 is the fact that it can be re-barreled to almost anything.
My #1 started out as a 30-06 and Epps re-barreled it to 450 / 348 Ackley Imp.
Its right on the heels of my 458 Win Mag. in terms of both performance and recoil.

As for the 300 Ultramag, why not give Epps a call and see if its doable, or maybe one of our forum gunsmiths will chime in..
 
Thanks all. My reason for re-chambering is that I already have a .300 WM that I love. I bought the #1b, because I don't have one in the safe at this time and wanted one. I have 4 guns in at Epp's for repair, so I might speak to them about this job. I'm trying to establish a Year of Manufacture for my rifle. The serial # is 130-16###. The scope bases don't have the "keyway" cut in them.

Two Dogs,
What's your son using for rings, I will need medium offsets on mine. I don't know why Ruger would space the rings so damn frar apart! Maybe to sell you another set of rings!LOL.

Your No 1 was made in 1975 according to the Ruger website.

That's the 1st I've heard if No1's not having the slot in the mounts. Knew there were early 77's that were that way, but not 1's

I believe he has one ext ring on it. Yeah, it seems the No.1's are a better fit for the long armed mountain man. Sometimes we nibble a little off the buttstock, on the one's that are keepers.

I'll post a pic later tonight. Could be the bases are not original to the rifle, being as how it's 38 years old.

Thanks for the research, m777! Here's pics of the bases. It's been years since I've owned a #1. The last one was a #1h in .458 WM. Had no trouble scoping it! Before that a 1V, again, no problem with scope installation. This one because of the base spacing is prooving troublesome.

Notice how far apart the bases are? C to C, 7.5" apart!

I've been looking at other Forums regarding this rifle, and it appears to be a 1V, not a 1b, as previously stated. The 24" barrel makes it a 1V, and the fact that it uses target blocks to mount the scope. I never considered the .300 WM to be a Varmint cartridge!!! It seems that this rifle was made to compete in Silhouette shooting and that when they banned belted cartridges, the rifle was dropped. Obviously, I'm seriously lacking in knowledge regarding Ruger #1's, so feel free to educate me. Here's a pic.

Definitely a 1V, but those do not look like original blocks (mounts) to me.



I have a 1b in 7mm Imperial Mag (predecessor & ballistic twin to RUM) re chambered at Epps on original 7mm Rem Mag.

Also have a unfired take off barrel that keeps tempting me to "re calibrate" ;)

Mark,
The blocks are original to the rifle. I've been in touch with various Ruger guys on different forums and prior to 1976, the 1v in .300 WM came with "target Style" blocks, to be used with target scopes such as Unertl, Lyman or Redfield 3200. My rifle is a 1975. The later ones came with the same blocks but had 2 extra holes, 3.5" from the rear block to mount a "modern" scope. I've been advised not to modify this firearm as it is quite desireable & collectable. I'm told around 200 made possibly, no more than 300. I would like to play with this thing, if I don't sell it. My options are limited: Have a front block installed, as the regular Ruger rail won't fit, or buy a target scope, likely a 3200, and go shooting!

Mike
 
Are those mounts for an older scope with external adjustments perhaps? They look like Unertl style blocks and the spacing is right (7.34" I believe).

Chris,
That's exactly what they are! The rifle was built for silhouette competition, but Ruger was a little slow getting their act together. By the time the rifle hit the maqrket, the Governing body had banned belted cartridges because of damage to the targets, and the rifle was discontinued.
