Will the .30-06 rechamber to .300 H&H go cleanly? The shoulder on the 06 looks rto be pretty slosde to the H&H.

The rifle is a Ruger #1B. Are there any other problems I ned to be aware of?

Thanks,
oneb

I have a B78 Browning in the vault that was successfully converted froma 30-06 to a 300 H&H. No problems with the conversion but the B78 has an extractor problem.. I Hate that action!! But I'll work out the bugs this summer(I hope) and maybe use for a deer or two this fall... Yes it will work.. It already has!

gunnut69,

Glad to hear it, thanks!

I understand that the extractor on the 1B has to be honed a bit to grab the H&H case correctly. This might be part of your problem.

I figure the smith can also just install a .300 WinMag extrtactor oin the IB too, as it is the same size as the H&H extractor... Should work but what do I know ...??

Good news. Absolutely no practical reason to do this re-chamber job. If you use the Federal HI-Energy 30-06 rounds with 180 grain bullets out of a 22 inch barrel, it duplicates the factory loading of the 300 H & H Magnum. I believe that these rounds come with Barnes X or Nosler Partitioin Bullets. Also, look at the Hornaday light magnum 30-06 rounds. I have chronographed these loads, and believe me, you've got a 300 H&H.

If you want to shoot heavier bullets, consider rechambering it to .35 Wheelen, or just trade for a .300 Winchester.

Best Regards,

I suppose you have a point Bigpaulie but remember, there's no substitute for case capacity. While the 30-06 Light-mags are great ammo a 300 H&H can be loaded to deliver more power. The No.1 does somewhat negate the biggest advantage of the H&H round, the smooth feed characteristics, but it is still a great cartridge. I would assume oneb knows of the availability of more powerful rounds, even the 300 Weatherby or the 300 RUM, but still has an urge for the old 300 H&H..

Big Paulie & Gunnut69,

I want a .300 H&H #1 for a bunch of idiosyncharatic reasons that do not speak highly for the soundness of my reasoning processes or even commonsense. Forec into a corner, I would probably even concede some good reason for not doingthis project but let's just talk about incentives to do it.

To dispense with the really arbtrary point first, I like old,
traditonal stuff and cut my teeth as a kid reading about hunters using this venerable old cartiridge with complete reliability and satisfaction. Good things should not die out...

In descending order of whimsical choices, my other reason would be....

It is not a short mag and this tickles my anti-herding nature.

I really like Ruger 1Bs and have a start at a modest collection of shooters -- not safe queens. Almost al the otehrs are stock -non-exotics models...

I can offset another of Ruger's marketing errors. Ruger never offered the .300 H&H in a regular producton run of the #1 yet the #1 package is perfect for the .300 H&H. It combines decent weight, fine blance and 'feel', and a 26 inch barrel to wring out the max in velocity.

The .300 H&H is reputed to be a very flexible cartridge with good accuracry across a wider spectrum of bullet weights and types. There is even some lore about it shooting to the same POI with different bullets and weights. I plan to explore that.

It certainly handles heavier range bullets more effectively than an '06. I find it hard to imagine any critter in the lower 48 it would not do a serviceable job on.

My best reason is that it is the heaviest recoiling round that I have comfortably shot after shoulder surgery. My Rem Classic is not much more punishing than my .35 Whelen -- a tang safety Ruger.
(While I like it, if the #1 works out--- the Classic will go on the block.)

The conversion is relatively inexpensive and easy. Not much to go wrong.

A .35 Whelen #1 may be my next roject.

Regards,
oneb

I like your line of reasoning. :grin:

longwinters,

What part of the UP are you from?

I used to hunt and fish around Deerton on the Laughing Whitefish as a kid. I imagine there probably are golf courses and brie shops up there now.

I'm in the process of having an old P-17 redone from '06 to 300 H&H. Why? Because... :grin: The gunsmith doing the work said no problem. With three '06's in the lock box already and the old girl had been partially sporterized already (stock changed, 'ears' ground off for a scope) I figured it might as well get a new lease on life and opted for a "classic" cartridge to go with the rifles vintage. Will probably add a Boyds stock (looking at the 'varminter') just to round the project off.

I now see the very excellent reasons for the conversion. At any rate, everybody has to do something in life that keeps them busy and keeps them happy!
