Going to start reloading for a 25-06, and hope to use 115 Noslers. In searching the web, I found several posters recommending magnum primers for the slower powder like RL25. None of the reloading manuals I have recommend these primers. Any thoughts?

It really won't matter one way or the other in all probability. You might find with a particular load that there is a preference indicated by a little better accuracy for one or the other, but it would be unlikely.

Just do not intermix with regular primers. Start 10% down and work up just as you do with regular primers.

It’s nothing to worry about. I think you’ll find better accuracy with regular primers but you wont know until you try them.

there's no reason to use magnum primers in the .25-06....however there is also nothing to keep you from using a magnum primer either.....

I use standard LR primers....do what you like!

To get the most out of RL25 in a 25-06 you are going to be looking at a very compressed load. While not my first powder choice it might work fine.

A maximum load of RL25 is still only around 60 grs or so. It will light off fine with a std primer. I've always found std primers more accurate than magnum. Unless I starting a real large case full of super slow hard to light powder I never go with a magnum.

i use fed 215's in mine with rl 22. shoots great but i never tried reg primers to compare to.

I always use magnum primers with the slower (RL19 and slower) propellants.

unlike other stick propellants they are "dua;l based and contain significant ammounts of nitroglycerine.

Nitroglycerine burns slower than Nitrocellulose (single base)
but has more than twice the energy by weight, but brings that energy to the burn cycle pretty late in the party...

Using a hot cap gets the ball rolling early and gets the nitroglycerine working.

The -06 case (approx 60 grain capacity) is about where I would start with magnum primers. As others have pointed out, it might, or might not make a difference. I would, however, make them my primer of choice if heavy bullets and slow burning powders are on the menu.

You likely won't notice any difference. Use whatever you have on hand.

Some people who hunt in very cold climates (< 0F) claim that "magnum" primers perform more dependably than standard force primers. Maybe, but I hope not to find out, myself!

AA MagPro has been my first choice for more than 6 years...it was designed with the WSM's in mind but works great in my Colt\Sauer 25-06. Lots of speed and accuracy with no pressure signs. I light it off with standard primers.

i use WLR PRIMER with IMR-4831

If it gets that [bleeping] cold, I'm staying home!

I have used just about all of the powders mentioned in a standard 25-06 with great succes using only standard primers, and am now working with an Ackley Improved version using enough Ramshot Magnum to hit the bottom of the neck, and being lit very well with CCI-BR2's. They are getting a SD of less than 20fps for a 10 shot string.

I only started playing with it this past weekend but it is showing great potential. Hopefully I will be able to tweak it in over the next couple of weeks to be as accurate as the other one.

Good luck.
