308 Norma

Since I have several 308 Norma Magnum rifles, I have plenty of data if you want it.
Started loading for this chambering in 1967....so it's been a year or two, lol.

My pet load in numerous rifles has been with Norma MRP...but Reloder 22 is close to identical in burn rate.

I work up to 75/76 grains of MRP behind the 180 Accubond or Partition. [Start at 72, and go up from there.]
H4831sc also works well, in similar charges. Another dandy in 2 of my rifles is 76 grains of IMR7828

With the 200 grain bullets I have a couple of rifles that really like Reloder 25.....at around 78 grains. Again, start 3 grains below and work up.

Which rifle is your 308 Norma in?

Regards, DaveDave.

Sounds like we started 'rolling our own' for the .308NM about the same time:) . I've had two rifles chambered for 308NM, my favorite 30 cal magnum. The first was a Parker Hale Super Safari but after seeing one in a Schultz & Larsen, I was hooked and had to have one. A Schultz & Larsen model 68DL is what I presently have.



Accuracy has been excellent, especially with bullets 180gr and heavier. Probably my best accuracy has been using the Sierra 200gr BT and IMR 4350. The load on the target has been the one that has performed the best for me but start a little under that load and work your way up, if need be. Oh, another variable in my load is my C.O.A.L., which exceeds the 'suggested' listed in the Sierra manual. I did this to minimize the freebore which I feel has helped to improve the accuracy slightly.

 
Out of my Browning Safari FN I use 71.5gr IMR 4350/150gr for a 1/4 mile deer electrocuter...[makes one ragged hole]....72gr of either RE#19 or H4831 [same sized groups doesn't matter which in my gun] and a 180gr bullet......the 72gr recipe for the 180gr is the same when I used 168gr Barnes X bullets........my gun is special as it likes almost anything.....I reform from free range brass .300 Win mag....Harold
 
Make it out of free range brass .300 win mag/sized +trimmed or if a short neck doesn't bother you .338 win mag.......Harold

If you check, there's a bit of it floating around. Most of my 'supplies' for a number of calibres I pick-up at gun shows,;) like the one in Naniamo tomorrow:). In my reloading room, I store my brass in stackable plastic trays.



2nd stack from the left, top tray, 1 dozen boxes of once fired .308NM. Admittedly, brass for this calibre is easily made.:redface: I just have a bit of an aversion to using something without the correct head stamp, if at all possible. My two exceptions are the 219 Donaldson Wasp and the 375 Chatfield Taylor.

I saw a bag of it at Corlane's in Dawson Creek not long ago. Didn't bother buying it for two reasons:

1. I have a fair supply laid in already.
2. The price would scare flies off a dungpile. :)

Cheers, Dave.
 
Yes the price of a correct headstamp on brass. I bought a 308 NM in a Parker Hale, the second rifle in this caliber i have owned. It became a project and is now my rough use general purpose rifle, something one need not worry about scratching. The other rifle was one of those i should never have sold.

Bought this one because it came with 7 boxes of handloaded 180 partition ammo, 7 boxes of 190 matrix loads, and 11 boxes of once fired Norma brass in Norma boxes. All for $500. None of this is for sale. Sometimes i am capable of learning lessons.
 
308 norma mag

Hello eagleye fairly new to this site but on my 3rd 308 NM .love this calibre . reload extensively for this gun . long story why I am on my 3rd rifle .Anyway right now powder is kind of scarce .Right now I am fiddling with IMR 7977 and h4350 . Moved to BC about 1 year ago ,reside in Prince George .If you have any data with those 2 powders I would greatly appreciate it .Back in Alberta I used this calibre quite a bit , i.e. largest moose ,largest bear , performance was awesome ; and this calibre was not fussy to reload . anyway hope this message gets to you ...later doug
 
Starting in 1964 I spent two years behind the gun counter in a store that could buy Schultz and Larsen rifles and all Norma products, directly from the distributor, thus by-passing all wholesalers. The result was a lot of these rifles and Norma products were sold. The S&L rifles were nearly all in either 7x61 or 308 N mag. And the Norma ammo for them was loaded HOT. One fellow bought a 308 NM, took it home and after firing one shot, the bolt was locked solid! He brought it back to the shop that way, I took it to the back room and with a spruce 2x4 a foot and a half long, I whacked the bolt. Hard. After the third whack, it came open. The owner had done nothing wrong, except he didn't clean and polish the chamber! The rifle was fine after, and with a clean, dry chamber. The 7x61 rifles had to be treated the same. Only they did have a problem, and even the company wasn't sure what to do, except they lowered the pressure on Norma ammo and on Norma loading charts. The new ammo had a different head stamp.
At that time scopes were just getting popular and many hunters wanted their scoped rifles to be sighted in when they bought them. Thus, I did a lot of sighting in rifles, of all makes and as I have said before, the most accurate rifles I sighted in were the Schultz and Larsen in 7x61 and 308 N. Mag. I felt so good about them that I once took a 308 S&L in 308 N. Mag, to a country turkey shoot. The only problem was it turned out the shooting was from off hand, so I could have made a better choice on a rifle to take!
And their best accuracy always came from full blown loads. Norma 205 had just came on the market and we loaded right up to their specs with it and the pressure seemed to be the same as the hot Norma factory loads.
I think, without doubt, that best powder for them is in the range of Norma 205, or the original, war surplus, H4831.

308NM was my favorite cartridge years ago in my P-H rifle.
The best accuracy and speed performance from 180gr bullets before even NMR and Rl 22 entered the market, I was getting from H450 powder.
I still have 1.5 lb of it stashed away and intend to build myself another 308NM P-H rifle (have action) with S&L Palma barrel for this year experiments.
Reg weight rifle at 7.5 to 8lbs would be to violent for the old fellow like me (65yo) but heavy barreled 10lbs one with scope should be just about right.
My friend Mick McPhee over the long conversations was positive than 308 NM with heavy 200gr+VLD bullets was the best 1000yd performer.
GR8 2c worth....
