Home Forums Hunting & Shooting Express Rifles and Big Bores Only Ruger 77 Tang 7 mag rebarrel to what??

Can you tell me about the front sight please?

That front sight is a CZ 550 Magnum front sight that I beat off the donor barrel with a propane torch and a hammer and large screwdriver used as punch.
I cut off the rear of the ramp where I had beaten it, polished and cold-blued the cut end.
Then I hammered it onto the McGowen barrel using J-B Weld as grease.
Patridge insert is from NECG, where you can also get different heights of the original CZ factory bead iinsert.

... if his cheek bones are not too broad to use iron sights.
Stock is better for scope use.

I asked the same question regarding what iron sight I should put on my 3575 Whelen AI. I got the same advice as what Rifle rank wrote. I am very happy with it.

I would love to have that sight on a few lever actions.

Mike78, the NECG front sights are pretty similar and easy to install yourself.

Thank you for that reference. How long is the base, as I have barrel bands to consider, though I guess they could be cut?

From the band to the tail of the extension is approximately 2 1/8", and yes it could certainly be cut. I'll likely cut down my next one somewhat just for aesthetics on a short forend stalking rifle I'm doing.

Run it by me again what a 175 gr nosler Partition in the 7 mag won't get done that you need to do?...mb

Pretty funny that a guy calling himself "Magnum Bob" comes to the big bores forum to advocate small bores. Not trying to be a prick here, it's just funny to me.

I have a Ruger 7mm RM and that barrel is to thin for any re-bore, I think. I’m going to re-barrel mine.

I’ve built a number of 375/338s on that action for my customers & friends. They’ve taken a lot of Buffalo, moose grizzly & African plains game with them. One came home from Africa and called me ordering another one. The PH was so impressed when he shot a hippo end to end, he gave him the rifle.

375/338 would fit in between a 375 Whelen AI and a 375H&H AI, I’d think.

What barrel did you use? Stainless Steel?

I suppose I’ll never need one, BUT!!!

BECAUSE AMMO WOULD BE EASIER TO FIND IN THE WORLD AND A 20 INCH BARREL TUFF TO BEAT A 375 H&H

The H&H is a bit long in a Ruger 77 and I have a 375 H&H AI pre-64 Model 70
I tried to sell my 7mm RM tanger for $200 less than I had in it. Didn't sell and I'm not giving it away. I've thought about the 458 Win. I'd probably want to shoot cast bullets in that. I have several other 45 caliber rifles and I have molds for 45.
I was quite sure that I had read somewhere that the 458 didn't shoot cast bullets well. I'm looking at Ken Waters July 81 article on the 458 pet loads. He seemed to get a couple of good accuracy loads with the cast bullets in his rifle. But he complained quite a bit about difficulty in cast bullet accuracy What say you?

Too long for the Ruger.

Mostly used shilen (CM). But had Douglas do a special contour on the last one that turned out great. He’s shot 4 Buffalo, 3 leopards & a grizzly, among other things, with it.
No stainless. I just can’t get into them for hunting rifles, although I built one for a goat hunt using a Ruger tang safety action 7-08.
There are many neat things you can do with that action.[img]https://ibb.co/QXqjkh6[/img]

Barrels may still be available from Gun Parts Corp (Numrich Arms). Haven't looked recently but they had 458 Win Mag factory barrels for No. 1s relatively recently.

TS M-77 is a straight conversion from the 7mm RM to 458 Win Mag just with the rebarrel, though you may have to slightly tune the feed ramp for the larger diameter bullets especially if you plan to use flat point solids. For your purposes, many 0.458" diameter round nose and rounded HP bullets are available so they may feed with the factory ramp profile.

The 375 Ruger idea is a good one, though I'm not sure how well they would feed through the PF TS M-77. You would need to see if the TS follower works or if the 375 Ruger Hawkeye follower would be needed. Again making up some dummies and trying feeding would answer that question. I can try it in my 458 TS M-77 and let you know how well that works as I have some dummies already made up, if you consider that route.

You could make up a few dummies with the bullets you intend to use and try feeding up the ramp as is with the long TS factory magazine follower in place.

BTW, if you get a tapered expander plug (a couple of diameters in steps) you can even form your 7mm RM cases to straight wall 458 Win Mags as the latter are hard to find right now. 300 Win Mag cases also work as a starting point. I anneal the smaller caliber cases before expanding to 458 Win Mag.

your right i forgot that length , so 338 Win. mag

358 Norma mag!!! i need won in my collection, I'm on a roll!!
