30-06 Primers

[spires5d]

I have a question. Would it be ok to load a magnum primer in a Remington case with Nosler 165 GR. bullet and 59 graines of H4350 powder?






Noslers Rock!

Is this powder charge safe for your rifle with std. primers? If it is the normal rule of thumb is back off alittle, 2-3 grains & work back up slowly with magnum primers, as they are hotter. I am about to find out how hot RWS std. primers are now, I have a bunch. I mention that because all brand primers can vary, so any time I change primers I do the above procedure.

In the broadest sense, magnum primers can be substituted for regular rifle primers safely, but generally speaking, magnum primers in a 30-06 are unnecessary. Make certain to work up the load safely, beginning at least 5 percent below maximum charge and work up carefully.

I assume you are loading for a 30-06, since that is included in the thread title. I am not certain where you obtained you information for the load data, but the current Nosler Reloading Guide lists 57.5 grains as a maximum charge with 165/168 grain bullets. By that criterion, 59 grains would be excessive, and the use of a magnum primer would increase pressure. Nosler ballisticians use a WLR primer in developing the loads listed. In general, if you are uncomfortable launching out on your own, it is not a good idea to alter the recipe provided by bullet and/or powder manufacturers as the listed loads are all pressure tested.

H4350 is an easy to ignite stick powder. Although either would work, you would probably have better results with a cold standard primer, think CCi 200's, or cci BR's. But considering how hard it is to get primers right now, most magnum primers will work just fine. A fed-215 might be just plain too hot and shoot like a scatter gun, but most other will probably work fine. Back off 2-3gr, work up, and see what your gun likes.

I tried 56 grains of H4350 with the CCI 250's in my Sako with no problems. Never went higher. Didn't feel the need to. Switched back to the CCI 200's and didn't notice any change.

Noslers Rock!

I'm shooting the same load in my 30-06's Hodgdon has that load at 2938fps. In my Lilja barrel 59gr/H-4350 gives me 2990fps with 165gr Partition same load in my Bartlein barrel 30-06 give 3076fps. Got to love those 5r barrel from Bartlein. I ran some 168gr TSX with 59gr/H-4350 the Lilja barrel gave me 3044fps and Bartlein 3054fps both those barrels have a 1/11 twist one is 24.5" other 25.5" long

I ran some Fed 215M primers didn't see alot of difference in velocity.

Another powder I've had good luck with is IMR-4350 and 165/168gr bullets you can work up to a max of 60gr.

Well good luck

How were your groups with the 215's?

How were your groups with the 215's?

Couldn't tell the difference. I ran alittle test with primers in my custom 270WSM using 58gr/IMR-4350 with 150gr Sierra.

Primer Rem 9.5M @ 3045fps
Rem 9.5 @3047fps
Fed 210 @3044fps
Fed 215 @3038fps
Fed 215M @3040fps
WLR @3050fps
WLRM @3043fps
CCI-200 @3036fps

Got a good Lawton barrel on that rifle and had that rifle throated alittle longer.

I currently load my brother's .30-06 with the 165 Interbond (he's too cheap to buy the AB) :roll: I use 57.5-H4350 over a Fed. 215 mag primer simply because by the time our rifle deer season rolls around temperatures can be well under freezing. In the next couple of weeks i'm going to "tweak" this load a little bit :grin:

 

[FOTIS]

Mags are hotter so adjust powder charge.

 

[Antelope_Sniper]

That's an interesting test 30-338. Thanks for sharing.
Highest velocities with the WLR primers, Just goes to show how some things can be counter intuitive.

 

[baltz526]

one thing to remember. the highest velocity might be acheived with the coolest primer, and the highest pressure might be at the slowest velocity with the hotest primer.

I have bought the latest nosler and barnes reloading manuals, and see that the max loads listed are lower than older data. I don't know if this is to be well below safe maximums or if new ways of measuring pressures are more accurate. My Oldest reloading manaul printed in the late 60's, shows 59gr. of h-4350 as there max load. I know a lot of mag writers say companys are playing it safe to avoid being sued,by guys not properly working up a load. that said I've stayed with 55gr. standard large rifle primers.

 

[DrMike]

Pressure measurements are more precise, and there is always the added factor of lot to lot variation in powders that likely accounts for some of the variation. I know that some loads from older reloading guides are hot for my rifles. This is the reason we work up a load each time we change a component.

 

[bobbyrum]

Dr. Mike is spot on as they say. My 7mm RUM showed serious pressures while I was working up my load using the 160 AB & Retumbo powder. My max load proved to be well under max indicated by Hodgdon; certainly not a "shot"at Hodgdon. I use their powders exclusively. The point is that I lost a number of very expensive cartridges during my testing due to oversize primer pockets :x Although I didn't start at max, I also did not start low enough Costly mistake for sure

 

[30-338]

here was a test done by Barnes

All in all, both cartridges shot the 200-grain TSX FB very well. The .300 Weatherby Magnum accuracy was outstanding, with all 300-yard groups measuring less than three inches across. Most 100-yard 10-shot groups measured an inch or less in diameter. The .30-06 Springfield also performed well, with all 100-yard groups less than 1.5 inches across, and less than six inches at 300 yards.

*Note. This test reflects results obtained from one magnum and non-magnum primer, using only three selected powders. Testing was limited to firing 10 rounds with each powder-primer combination. Results are for general comparisons only with these specific powders, and should not be considered statistically relevant.

I sure hope nobody thinks I ran that test without working loads up. The advantage I have is I load at the range.
