Standard primers vs magnum primers in 30-06 using rl 26

So here is the thing. going to try some reloader 26 in a 30-06 shooting with180 grain flat base bullet. I have Done made up the first test round using the standard primers 210F but have not shot them at the range. Started at 58.5 gr and going up in charge weight. My question is would there be any discussion on using the magnums 215 primers since the case fill is so high and the burn rate of this powder.
In the past the only thing I've done is try different primer brands.
Additional info. Reason I'm trying RL26 is trying to find a couple powders for all guns I reload and the H4350 I typically use has been a little challenge to get my hands on but not impossible. If this don't work with RL26 I'll just go and find some 4350.

The 06 doesn't need mag primers because of the powder volume but you could try with reduced loads and see the effect on SDs. I find a difference in cartridges that have 70+ grains of powder capacity.

A lot of people use them because they increase the velocity, but they can hurt the consistency in the SDs.

Plus one what J E CUSTOM said. When I first got load info (from a forum member) for the .300WinMag using 212/215 class bullets and RL-26, the shooter listed CCI BR2 primers. I thought that was odd and tried several magnum primers. All gave lousy ES/SD's and accuracy was not up to what I wanted.
I started over using the BR2's and the guy was right. They work great with 75gn's of RL26 and velocity is consistent (over 3K) with ES below 15 and SD in the single digits. I shot a four shot group yesterday at 100yds in the .3's.

I found just the opposite with my 30 06. 62.4 grains RL26 with the 190 Berger and the 215 primer got me better and more consistent ES. 2880fps with 18ES. Just my findings though. The 210 primer had less velocity and the ES was in the 50fps range.

I think the best overall answer is try them and see for yourself. You never know as it seems every gun is different.

Reloader 26 is a double base powder containing nitroglycerin and will have more deterrent coatings than single base powders. Meaning double base powders are harder to ignite than single base powders. I'm old fashioned the older reloading manuals always used a magnum primer with double base powders.

Lake City uses magnum type primers with its 5.56 and 7.62 ammunition.

And you use magnum primers with slow burning double base powders in the .357, .44 magnum, etc. And these pistol cases have far less volume than a 30-06 case.

When I load double base powders I always think of the Doors song " Light my Fire" and magnum primers.

CHOOSING THE RIGHT PRIMER - A PRIMER ON PRIMERS

How fast a powder burns depends not only on granule size (bigger granules have more relative surface area) but on exterior coatings. Extruded powders, such as relatively small-grained 4895 or large-grained H-4831 depend mostly on granule size to control burning rate. Ball powders don't vary much in granule size, so depend mostly on relatively flame-resistant exterior coatings to control burning rate. By definition, these coatings make ball powders harder to ignite.

For example, in the 30-06, IMR 4895 is very easy to ignite, one reason it's often suggested for reduced loads down to 2/3 of a case's capacity. We'll probably get the very best accuracy from a mild primer such as the CCI 200.

To make the 30-06 zip however, we might try Ramshot Big Game. The Ramshot ball powders burn cleaner than most ball powders, but they also require more flame. Winchester Large Rifle primers are the hottest "standard" rifle primer and often perform very well with Ramshot powders, but if they don't definitely try a magnum primer. This can often result in smaller groups.

I had problems lighting off 51.5 grains of R19 in a 6.5 Remington Magnum case with standard CCI LRP. I got hang fires. Only load a few to try out your powder/primer combination.

Good Luck

What works good in my Rem 700 30/06 is Winchester brass, Fed 210 primers, 63.8 grains of RL 26 and a 180 Accubond. This load produces 2861 FPS from the 22 inch barrel. I have been shooting this for 2 years now with great results.
This is a Quick Load work up that I got from a different forum. My rifle shows no indications of excessive pressure.
If you try it start low and work up slow.

I run magnum primers in my 30-06/180 NPT/RL26 load. Added about 70 fps and shrunk groups. ES was about the same.

For me I've had the best luck with Fed 210 primers in the 06. But I haven't tried the RL26 I set aside for it. When I can find some 215gr Hybrids locally I may get some Fed 215's also.

Use mag primers in everything. Not much difference in price an don't have to keep them separated

I use magnum primers in my 308,30-06 and 338-06.I get excellent accuracy with them so I see no need to buy standard primers since I load for magnum rifles too.

In my little 6mmBRDX, I use a magnum CCI primer (450) with RL15, and I have tried both magnum match and std match primers with RL26 in my 6.5-284. Neither seemed to work particularly well with 26... I had about 10" vertical at 1,000 yards using a Sierra 150 gr, but I forget the exact powder charge. I don't recall it being compressed very much, though.

Good reply fellas

Think I'll see how the standard primers group and watch the ES. If theES is high or the spread is open I'll back off a loads and try some magnum primers. read a lot last couple of days and answer vary so I guess I'll try the test and see what happens method. Some interesting reads on ES spread and using a standard primer vs a magnum in trying to reduce groupings.
