magnum primers in '06 loads

02 August 2003, 17:21

Does anyone but me use magnum primers in their 30-06 loads? Seems like the '06 is right on the dividing line between large rifle and magnum.

I went for years with large rifle. No problems. Good ignition, good accuracy. Then I ran out. So I started using from a brick of magnums that I had (backed the powder down 1 gr.)Still very accurate.

I am curious if you have run into any downsides of this practice.

I use magnum primers with the slower powders, like 4350, 4831, and the ball powders. Works well for me.

Kyna - I have NEVER seen an advantage to magnum primers in anything....other than putting an extra $buck in the manufacturer's pocket with each brick you purchase.

I'll probably get stoned to death for saying that but such has been my observation over some 45 years of reloading.

kynadog,

The '06 case size doesn't require a mag primer for good ignition. The only exception may be the use of slow burning ball powders during cold weather. That is the only time I think they might help. [Smile]

I have used them from time to time in smaller cases like the '06 and 7X57mm, but didn't see a lot of difference in either velocity, accuracy or APPARENT pressure. I don't generally use them in non-magnum cases. however. [Big Grin]

My experience tends to confirm the theory that magnum primers don't give any advantage in smaller capacity--maybe '06 or smaller--cases. Once I tried CCI magnum primers with a .223 load using Winchester 748 powder. Accuracy was poor. When I switched to a regular, non magnum, CCI primer, all else the same, accuracy improved considerably.

I use magnum primers in a 06 load that stuffs the case full of Re22. Other than that I have had good results with regular puny primers.

I have found that Magnum primers work best in Magnum rifles and standard primers work best in non magnum rifles, amazing isn't it?

Except that my 375 H&H seems to work better with the standard Winchester WLR (non-magnum) primer. Is the 375 H&H a magnum or not? Maybe, although it has a belt, it's borderline?

Nothing in cast in stone when it comes to what a hunting rifle will or will not like. I find that the 300 Winchester magnum case and larger is the starting point for using magnum primers. In my case my 300 Winchester magnum shoots fantastic groups with Federal standard large rifle primers. I see no reason to use a magnum primer in the 06 case except if your out of standard large rifle primers and the fridge has no meat in the freezer. Magnum primers were designed to produce a hotter flame that will ignite large powder charges for more consistant performance. If your rifle will group well with standard large rifle primers why use magnum primers.

It is always best to use the proper tool for the job being performed. Using High test gas in any engine designed to run efficently on regular fuel is not wise and a waiste of hard earned money. With over 40 years experience behind me reloading, I stick to the basics and find success more often than not. Reloading manuals contain many millions of hours of hard work and testing we need not do. Those men know their craft and I believe what they put in writing.
