I was straightening up my reloading bench and had put some components on my bed when my wife walked in the room and was looking at what I had lying there. She mentioned I had Large Magnum Rifle Primers and asked what they were for.

I'm color blind so didn't know they were Magnum primers, last time I bought Magnum primers on purpose was when I bought my last batch of them for .357 and I had her with me at the store so she could read the boxes to me. I loaded 10 .308 and 16 .30-06 rounds for my M1A and M1 Garand test rounds. Both the .308 and .30-06 are closer to starting loads. The powder I used is H335 and H4895, is it OK to use the Magnum primers or should I break them all down or would they be OK to shoot?


Before anyone asks, red is a color I have a lot of trouble seeing. There are days I can see it and there are days I can't especially if it's next to other colors like blue or green.

You didn't give the exact load, but if it is indeed close to a starting load you should have no problems.

41 grains for .308 (H335) and 43.3 grains for .30-06 (H4895) also 37 grains (H335 for .30-06) both using Lee, Hodgon and Hornady load data.

what bullet and case?

You'll be fine.

Military ammo uses a hotter primer than commercial -- closer to magnum brisance.  Not sure if that's to light older powder charges or to ensure consistent ignition at below-freezing temperatures as specified in mil-specs.

Examples are CCI 34 and 41 primers.

Save the worry and stress......use a bullet puller and start over.   You can SAFELY fire the primers once the powder is removed.   Then start over with the right primers.
Marking with a felt tip will help you see the differences.

Armscor 147 grain FMJ-BT, Lake City brass for .308 and Armscor 147 grain FMJ-BT mixed Federal and PPU brass for .30-06.

I know the Armscor bullets are garbage bullets but I'm only plinking.

With a starting load, the magnum primers won't be an issue, but the load will be different than if the intended primers were used.

Also feel obligated to add the obvious . . . if you know you are color blind, please do not rely on color recognition for safety. Your wife saw they were magnum, read the labels as she must have.

When I bought them she was not with me. I did read the label, what I read was Large Rifle Primers as the red lettering is invisible to me. I only know they're Magnum primers now because she read the label weeks after I loaded the test rounds because to me, the box still says Large Rifle Primers to me. I've used a yellow paint pen so I can tell they are Magnum primers. It doesn't make a difference to me because the red lettering is completely invisible to me against the blue background.

I've also ordered the proper primers.

I've read (in the reloading manuals) and on the internet that magnum primers are recommended for ball powders.  

Check your reloading manual and see what it says for H335 powder.

I used a lot of the CCI military LR primers with IMR4895 several years ago for my M1A (.308) and M1 Garand 30.06 loads with no issues.  No, I don't remember the powder charge.  Do some research (look at Hogden's website and reloading manuals and see what king of info they give on primers and loads.

Try taking a photo of the labels of your stuff with your cell phone and make it black and white in your photo edit function.

You should be able to read everything then.

Just to be sure.

From News-Medical.net
One of the most common forms of inherited color vision deficiency is the red–green deficiency or deuteranopia. This type of color blindness is passed on via the X chromosome and is more common in men who have only the one X chromosome, than in women, who have two X chromosomes. In men, the prevalence of color blindness is around 5.0% to 8.0%, while in women the prevalence is only 0.5% to 1.0%.

This particular form of color blindness is why it is now a national standard that the red (stop) light is at the top and the green (go) light is at the bottom of traffic signals.

AeroE is spot on.  The manufacturer needs to know that their packaging is not "accessible" to color blind customers.  This impacts the "target audience" of reloading supplies particularly strongly (men versus women).  Most powder makers use a combination of distinctive lettering, LARGE lettering, and color coding on their powder containers to prevent similar (and far more concerning) errors.  Primer packaging needs to be VERY clear.

My apologies, didn't suspect that was the problem. What I don't know about reloading is apparently only exceeded by what I don't know about color blindness :)

Colorblindness isn't just seeing stuff in shades of gray. Red and green disappear for me if they are on the wrong background or I don't shine enough light on em. This means that on packaging you can often see words, but I don't know they are there. At sunset every car on the road is either white or black, at noon I can get every color right.

I never understood the thrill of having lasers on guns, I can't see em

I'm actually surprised that you weren't having trouble with your H-335 load in the 30-06 using standard primers.

H-335 and 150s in our Garand hang fires using standard primers. With magnum primers they work great. I suggest you continue to use the magnum primers with H-335 in the 30-06.

Even using them in the .308 Win with H-335 is not a bad idea.

The overall difference in pressure between using a standard primer and a magnum in those 2 cartridges is very likely too small to even be significant. You would need to be on the ragged edge of maximum with a standard primer then switch to a magnum to even worry. But that would be true for changing any single component of a maximum load.

I haven't actually shot them yet, I've been so busy that I haven't been able to get to the range. I've been even more concerned since I discovered that I loaded them with Magnum primers so they've just sat in the reloading box.

It's funny you mention traffic signals. I've blown through plenty of red lights because they were in the green housings and I didn't know they were there because I couldn't see them.

I have the same problem, reds and greens disappear on certain backgrounds.

Don't they have glasses for people that are colorblind?

Thought I saw something about that recently

Don't know. I already wear glasses as it is. I may have to look into the possibility of getting a pair for the sole purpose of color blindness.

They work for some people with some kinds of color blindness.  The "disappearing color" type isn't typically helped with those glasses.  They help provide more contrast between certain colors, but not any help with "red (or green) on an arbitrary background."
