Home Forums Hunting & Shooting Gunsmithing REBARRELING 721 TO 300 H&H

I am thinking of doing a project that I really don't need but always wanted a 300 H&H.

I have a spare Remington 721 action that was a 30/06. I also have a excellent shape 722 barrel in 300 Savage with 1 in 10 twist. I would like to screw the barrel on the 721 action and have my gunsmith rechamber to 300 H&H. Dimensions appear to permit this. If I get a Rem 700 magnum face bolt would I need anything else for this conversion. The action is long enough but you there be any feeding problems.

Let me know your thoughts.

Thanks,

Bill

You would be better off buying a 721 already in 300 H&H.
Advantages:
-26" barrel
-correct bolt face and extractor
-correct bolt stop and magazine for 3.6" (vs 3.34") cartridge
- you can buy one for under $1000 (A model)
- add a 700 stock and you've got a fine rifle

My 1952 721 AC 300 H&H, a 5 shot sub MOA rifle with an equally ancient BalVar 8 in Leupold AdjustoMounts. (top one)



The 721 you have would make a great 35 Whelen or any number of 30-06 based cartridges.
The 722 300 Savage is a collectors piece if it has condition.

You can also find 700 Classics in 300 H&H for about a grand but they only have 24" barrels.

here are several options:

All you have to do to the 721 is open up the bolt face and install either a riveted magnum 700 extractor or a Sako style.

The 721 has a 3.7" mag box just like a 700 long action. They all have the same bolt travel, bolt stops are all the same.

Nothing wrong with a 24" 300 H&H.

I had a factory 721 in 300 H&H and the throat was very long. Had to seat about .180" off the lands to fit the mag box. Why not make a 308 Norma instead?

IMO just a waste of time and money when there are so many fine 721 300 H&Hs out there.

The long throat is set up to be able to handle the old 220 gr RN bullet.
Using TSXs, A Maxs, SMK or even plain old Hornady FB Hornady softpoints, mine doesn't care, they all shoot into 1" or less at a 3.6 OAL

26" barrel does make a difference when shooting slow none erosive powders.
My 300 H&h can equal any 24" 300 WSM or 300 WinMag with 168 TSXs and 7828.

Owned over a dozen 721s and 700 Classics in 300 H&H, even a Ballard High Wall in 300 flanged. Also dozens of other 700/721/722 s.

Chronographs don't lie.

You may do whatever you wish, but it does not make economic sense.

Been down the conversion road several times. Top one in a 300 H&H Classic converted to 400 H&H (rebore, new wood, "Rigby" bottom metal, muzzle brake)



Works great and shoots 400gr Woodleighs as good as a $50,000 genuine H&H Mauser.

Also own a 700 in 244 H&H, Red pad #1 went from 30-06 to 300 H&H and a Browning 25-06 High Wall that is now a .411 40-82 set up for those same 400 gr Woodleighs.

Been there done that. Some are easy (the 400 H&H) some are expensive bittches.
The 244, 30-06 #1 and 40-82.

Your 721 would make a great 338 or 411 Hawk AS IS.

The last 721 in 300H&H that I saw for sale was about
a year ago, price was $650. You dont see them everyday
but cheaper than building one.

I know where there is a 721 300 H&H for $550 looks pretty nice. Not sure if they will ship it but if your interested let me know and I'll give you their contact info.
