I'm wanting to build a 300 H&H mag from a rem 700 action but not sure if ill need a 300 win mag action or 300 rum action. I was also wondering if anybody had any suggestions as to who to go to for all of the work. thanks
 
Your will need the longer action, 300 win mag is an 06 length action. You need the H&H length or 'magnum' length action.
 
A .300 H&H does need a true magnum length action. I have a .300 H&H but I got a great deal on it in a 1917 barreled action that had already been modified to this chambering. Other than the fact that you can say you have a .300 H&H, it is kind of in between a .30-06 and a .300 Win Mag performance wise; so it leaves me with the question why do you feel the need for this caliber H&H instead of the .375?

Most commercial ammunition companies have dropped it from the line up and then when they do offer it is in limited loadings and it is expensive. This leaves custom ammunition which is even more expensive and reloading. Reloading is the best option, but brass is hard to come by and expensive again when compared to cartridges of similar performance. The big brother the .375 for all practical reason mainly ammunition and component availability makes more sense if you want to build an H&H rifle.
 
Well I did think about all of those things but I already have plans for a double in 375 H&H and after looking at the ballistics I think that the 300 H&H is a better round for plains game in the 250-350yrd range so that is why i decided on it. I reload so finding ammo is no problem and I just like the fact of being able to take a pair of H&H's to the dark continent.
 
Go for it, it would be very cool to hunt Africa with only H&H cartridges! I would stick to bullets 180 grain and heavier because from all my data this is where the .300 H&H really shines. Mine is at the smith's getting a new stock and some more action work done, I should get it back around Christmas.
 
I shoot an old FN 300 H&H. Very good long range round. Inherently more accurate at 300+ than 300 Weatherby or 300 Win mag. I don't shoot any of the new 300 mags. I have enough 30's, not usually my go to calibers. Handloads are best bet for cartridges. You might want to talk to Harry McGowen in ST. Anne , ILL. I don't know where you are. I usually don't reply to these posts , however the H&H is a favorite cal. of mine.
I shoot a lot of old cals. 218 Bee, 22 hornet 220 swift,30/40 Krag another damn good killer! .348, 450 Alaskan on the .348 case. I still shoot a .264 mag .I like some of the new cals. 223 WSSM .25 WSSM which is just about dead now,I think. .204 and others.There will probably be a lot of heat caused by my accuracy statement. I speak from experience in the Alaska range, brooks range Wrangells, Cassiars in the Yukon .
There are a lot of .300 H&H rifles for sale. Buy one Put Pride Fowler rapid reticle for 600 yds. and shoot .
Good luck with project ......... Chuck
 
i have a 300H&H in a rem 721 and a 375H&H in a rem 700bdl.

build the 300 or just look around...cabelas gun library has them ocassionally.
http://www.cabelas.com/cabelas/en/c...SO-8859-1&Ntt=.300+H&H&sort=gl&Go.x=25&Go.y=9

i love both guns but the 300 is my old faithful...

as far as reloading is concerned the 300H&H can be loaded faster than a 300 win mag! FACT

i have loaded 200grn accubonds over 67 grns of 4831sc. running around 2800 fps.(not a max load)

i know a machinist/gunsmith that could probably do it for you if you sant his info i can pm you?? the builds Fclass rifles for competition...very detail focused man.
 
Thanks flyguy I was actually looking at an old 721 in 300 H&H kind of curious how well yours has held up. What kind of group does yours get? If i bought one I would replace the stock first then probally do a Black t finish on the barrel and reciever. I would be interested in that guy that you are talking about where abouts would he be?
 
i too want to go to Africa with both of mine! maybe we should go together and have 4 Holland&Hollands

my 300 is one of the first built!in the 40's and still shoots gr8.
it used to hold sub moa with factory silvertip ammo...well since i have used that ammo up i have gone to trying to find a load. the 200grn accubond seems like it will be a good set up but i havent fired it enuff since put on a new stock and rebluing.

if you can find a 721 and it looks good buy it! seriously the actions are SOLID.

we are in south dakota, rapid city.

here is the 300

375.

i would recommend Jeff @ Accurate innovations to do the stock for you and then he can take it to Randall.

Wow Flyguy that is a beautiful gun! I was looking at claro wood also for that 721 it looks like yours is an oil finish is that correct? What kind of recoil pad did you put on there?
 
yes premium oil rubbed finish with all the pores filled. actually has a bit of "resin" in the mix to harden it a bit.

the pad is a pachmyer deceler8r. the only pad to buy!

like i said building a kick butt 721 is not that expensive. i have seen them go for 600 bux. then dump another 100 in the trigger, 6-1500 in the stock(depends on how nice you want to go with wood)

for around 1200-2k you can have a AN AWESOME CLASSIC.

pm me if you want numbers and names. just so you know i have nothing to gain by sending you to these guys. i dont work for them or get any kickbacks. they are legitimately good guys.
 
I think you'd be well ahead of the game getting a Remington 721.

They're still out there, underappreciated, and not bringing tremendous prices.

A custom stock job, maybe a new barrel if you're so inclined, and you'd be good to go.

I have not a 721, but two 722s in .300 Savage. One has been pretty badly butchered, but the other is stock. I've shot it a fair amount. Very accurate and not a hint of problems over the years.
 
i am having a 300H&H custom built at the moment on a k98 action. the gunsmith who is doing this has one and when i saw it i told him to build mine exactly the same. as we are limited in s-africa to the quantity of rifles we are allowed to have i knew that the rifle i choose should be the mother of all all rounders. i literally traveled the country and asking all the gunsmiths and gun shop owners i met "What cartridge do you recommend?"

their reply would always be "what and where do you plan to hunt?"

the recommendation would always be either 300wm or 30-06. but here comes the interesting part. when i asked them with what they hunt a mojority would reply that they hunt mainly with 300H&H. so when i first said i will have one of those i was informed that nobody has this rifle as a production rifle any more. however the kind of feedback i got from further inquiries convinced me that to spend the extra money to build the H&H was the way to go.according to our local reloading guide the H&H is faster than wm on the 180grn
with a few f/s. however the 150grn out of the wm is faster.

having hunted the last couple of months with a 300wm i think the difference in the wm and the H&H is unnoticeable with the naked eye, however i do enjoy the H&H's lesser recoil.
 
I would not choose a Rem. action for a 300 H&H. That design, both the 700 and 721 series do not have many features which make a good hunting rifle.

They lack CRF (controlled round feeding), a strong extractor (they only have that tiny weak spring), the bolt handle is only brazed on and can break off and they don't have a three position safety let along one that holds the firing pin.

I have a 300 H&H on a pre 64 M70. Thats a better design.

Savage99 so your saying that the bdl and sendero that I have an have killed numerous deer with aren't good hunting rifles? Here's a liitle trick too replace the 700 extractor with a saki one if your that worried about it.

ROTFLMAO!!!!!:p


That's why Remington won't last, they don't have the features needed to make a good hunting rifle...:rolleyes:
 
300H&H is same length as 375H&H.

300 Win mag is shorter, and Rem 7mm Mag is even shorter.

As such, the 300H&H has more powder capacity than 300 Win Mag.
 
I have inherited both a .300 and a .375 H&H made by Holland and Holland c.1955 and between them there is nothing on the face of the earth they can't kill and have done so--whether I'd go after elephant with the .375, even if it's allowed and will accompish the task, I'd still prefer a true stopping caliber of .45+ which I have in a Westly Richards doubles in .470 NE and .476 WR and a .425 WR bolt action all c.1955 as well--when six of my uncles went on safari...

When H&H rounds became scarce I acquired a .300 Weatherby and used that a lot until the scarcity dried up and I've gone back to the H&H as it is very accurate and with a lot less recoil then the Wby or Win mag...Now, that I reload, I don't have that problem anymore except for getting brass, maybe!

You will be hunting with a true classic calibre, nearly 90 years old,
Introduced in Britain in 1925 by Holland & Holland as the belted rimless magnum not to be confused with the .300 H&H Flanged NE...
180 grain Soft Nose Bullet
Muzzle Velocity 2750 ft/sec Energy 3020 ft/lbs BL 26"
220 grain Soft Nose Bullet
Muzzle Velocity 2300 ft/sec Energy 2115 ft/lbs BL 26"

Although you have to go to European ammo makers for the cartridges, I can't remember who made it, but there was a 165 or 168 gr bullet for it that was just devastating on deer and pronghorn at around 3,000 fps...When you get it buy lots of ammo for it, 200, 300 rounds maybe even more between the two/three major loadings and this way you won't run out...you can always have your empty cases reloaded by a friend or a custom loader if you don't do it yourself, which you really should...
 
The .300 H&H made its competition debut in 1935 when Ben Comfort used a Griffin & Howe modified M1917 Enfield chambered for it winning the 1000-yard Wimbledon Cup with it. Folks shooting long range matches demanded it as it was a better round than the .30-06. But only by a slight amount as the .300's muzzle velocity was originally only 100 fps faster than the '06 for a given bullet. A few years later, Winchester chambered their Model 70 hunting and target rifles for it because of the demand for this "magnum" cartridge. Several Model 70's were bought in the 1950's then rechambered for the .300 Weatherby costing much less than buying a Weatherby rifle and getting Roy's new cartridge to shoot.

People handloaded .300's to get a bit more muzzle velocity and it stayed in its place as the favorite 1000-yard target cartridge until the early 1960's. In 1959, Fred Huntington (RCBS founder) sized .338 Win. cases down to 30 caliber naming it the .30-.338 and this cartridge was the death knell for the old H&H round in rifle matches. Its shorter, fatter case enabled lower muzzle velocity spreads virtually eliminating vertical shot stringing at long range.

SeekHer mentions the .300 H&H Flanged (Rimmed, for us North Americans) being the basis for the .300 H&H. That belt on the case prevented the flange/rim from hanging up in loading from box magazines, yet also let the same round be used in double rifles. A really good idea; one cartridge fitting two rifle types and functioning reliable in both. Those crafty Brits have many shooting sports ideas the world's benefited from.

Savage99 and davlandrum, your comments on Rem. 7XX are interesting. For what it's worth, some of them shooting heavy recoiling rounds have had their recoil lug bent forward. To say nothing of many extractor failures. And those round receivers tend to twist loose from epoxy bedding from barrel torque when heavy bullets go down the barrel really fast. Box magazine versions are only about 1/3rd as rigid/stiff as a Win. 70 receiver.

i see that a couple of the posts here mentions the scarcity of ammo. until now i havnt had this problem over here in africa. we have a local company by the name of PMP that has a production line for this caliber. this just goes to show the popularity of this calibre in africa. however most of the shelf ammo in my possession are american. that is why i worry when i read american posts of ammo being scarce. it seems that was temporary?

a not so well known fact about the UK based Holland&Holland company is that it is South-African owned.

though the 300H&H can do high speeds such as 180grn @ + 3000ft/s the local hunters of s-africa are not fond of high speeds. by far the largest majority of game being hunted in s-africa is hunted by local hunters that dont hunt trophy's but are "biltong"(meat) hunters. thus the wide range of bullets that can be reloaded at less speed(less meat damage) but still retain more than enough energy, has ensure(the 300H&H) a legendary place in Africa.

the H&H is perfect for this: to hunt Eland Gemsbok and Wildebeest and so on at great distances. it is a 30 caliber with long distance ability and average recoil. so it is suitable for all day game harvesting. Harvesting- roughly explained as taking more than 10 heads of game per hunter per night for venison purposes. ie for export or local markets.

though at the moment i would say the most popular caliber for harvesting of large game at night such as Gemsbok or Wildebeest is done by 25-06. even the H&H's recoil is too much if you have to take a 100 + wildebeest a night.
