Home Forums Hunting & Shooting Custom Rifles & Wildcats 300 Win Mag to 28 Nosler ?

I have a Remington 700 in 300 WM that I might rebarrel to 28 Nosler. What changes will I need to my Remington 700 action to make it feed/function correctly ? Mag box, follower ?

I had a 7 Wby rebarreled to 7 Dakota and it required no changes at all to feed rails or bolt face, functioned well. I don't reckon the 28 Nosler is much different than the 7 Dakota.

I had two 7RM 700 BDLs converted to 26 Nosler, one for me, one for my hunting bud.

The fat, Nosler round would not pass thru the action rails on either 700, but would easily pass thru the rail of a Magnum M-70. Go figure. The bolt face was OK.

These 700s required a fair amount of action work to feed the Nosler round, including a RUM mag box with "windows" for the fatter round.

The 28 Nosler should be about the same.

Open the rails
I used a 700 in 7mm
It will feed 1 from the mag fine ... put the 2nd round in the mag and top round will kick up........
Open the rails up and it works fine with 2 down

With the RUM box, you can squeeze three down, or use 2 comfortably.

Edited to answer OP's question about the follower.

Std. mag follower works. No change to 7RM M-700 follower with 26 Nos conversion.

So the follower I have from my 300 WM will work then.

It should.

The 7RM follower works in the 26 Nos.

It won't bother me to change out a mag box or follower.....I just don't want to be milling the action (opening feed rails) so that it becomes a permanent Ultra Mag action.

My M-70 Magnum action will pass a 26 Nos round thru the rails without a problem. But, I've read that CRF can be harder to adapt than Push Feed.

I'd suggest a discussion with your smith.

Sounds like a lot of work and a PITA. Why not just buy a Nosler rifle?

If you already have the action, as in a shot out 7RM, .300WM, etc., it's less expensive to add a $600 premium barrel than buy a Nosler rifle.

Although they're a lot of gun for the buck, us "do it your self" types like to do it ourselves...

For example, I bought this 7RM BDL from my gunsmith for $400. It had smoke damage from a fire, but didn't get hot enough to char the wood, so the metal temper wasn't affected. The toxic smoke had corroded the barrel beyond repair. Add $600 for the Shilen Match #2, pillared and glassed by me (I work cheap), I have a half MOA 26 Nosler. Actually spent a few more bucks getting the action tweaked for the fat Nosler round, but still way less than a Nosler and I'm not sure Nosler puts as good a barrel on their guns.

I couldn't move the trigger adjustment screws, so I picked up a Timney 510 on Ebay, delivered for $108. This new Timney blocks the trigger and sear, not just the sear, reportedly for consistency in pull. It's set at 2 1/4 #'s.

I already had the Z3 4-12x50 BT, moved it from another gun to this one where it's likely to stay.

RUM SS box with windows.


Sharpie marked yardages on the BT aluminum discs.

DF: RD has plenty of money....

That's one thing we do very well here on the Fire, help fellow Loonies spend money...

And, often it doesn't take but a small push...

The Nosler rifle with a good stock, non-B&C that is, is somewhere in the neighborhood of $2500 I believe.

The above 26 Nosler, similar set up for a 28 Nosler, set me back around $1,400.

I'd be surprised if the $2,500 Nosler would/could out shoot it.

Barrel it and see if it will work then if not modify the feed rails

Cases must pass between rails to get into mag box. Don't need it barreled to figure that one out.

Feeding after fitting the barrel may require some tweaking. Sharp shouldered cases don't generally feed as slick as the old tapered .300 H&H and .375 H&H. Those were made to feed slick and they do. With some work, sharp shouldered cases can function smoothly.

Geez....I guess it IS easier and cheaper to get a Rem 700 in 7RM and punch it to Mashburn. No feeding/modifications to the action and cheaper brass to boot.

But about 100-150 fps less velocity......

No wonder rifle people are crazy.

Probably.

Definitely no action work needed.

Just depends if one wants to form brass or buy it ready to go.

The Mashburn is definitely an interesting proposition.

Nosler rifle in 28 Nosler for $1799 at the Scheels store in Lincoln. I'd probably just keep shooting my 7mm Remington with a long throat.
