WLR/WLRM Primers

[Visionz45]

I have both WLR and WLRM primers. Ive switched to H4831sc for my .30-06(180gr. loads). I was told that the "special" coating on the powder may require the use of magnum primers. Has anyone had any experience with any of these combo's?

Check Hodgdon's site for loading info for that powder in your caliber, and see what primer they recommend. If it's a magnum primer, then use the WLRM. Don't take anyone's word when it involves your head and arms around the rifle.

I use 4831sc for 25-06 and .270 loads and use WLR primers. On the can they list Rem 9 1/2 and WLR for 25-06, 260 Rem, .270 Win, 280 Rem, 7mm Rem. Mag and 300 Win. Mag (30-06 not listed). I checked Hodgdon's web site and could find no mention of using magnum primers for 30-06 loads (I could only find 1 recommended 30-06 load using H4831 on their site). If you try the magnum primers I would recommend starting at 10% less than minimum and work your way up.

So if any of us have experience what good will it do to post it, referring to the bottom quote.

After reloading for 40+ years, I've found that the use of magnum primers is not really needed unless you have a huge case of powder to ignite or it is really cold. I know that this goes against the thoughts of some, but it is what I have found to be true.

I have loaded IMR 4831, IMR 7828, IMR 4350, H450, RL19 and others with LR primers in .243 Win, 25/06, 270 Win and 30/06. I had good results accuracy and velocity wise. I've used LRM primers in those same loads with very little difference in either accuracy or velocity, at most you may see a few FPS faster with the LRM primer. Of course you should back down a little on the charge for the LRM. That really only applies when you are getting close to a max load.

If you are using a middle of the road load for say the 25/06 and you run out of LR primers and you have some LRM and load those, I bet most folks would never know which was which as far as accuracy or velocity. Now if you were at max then you could see over pressure signs and would need to reduce the charge.

I advise caution when swapping componants, but there is a lot of BS out there as far as primers go. Be careful!

Now when folk are talking cold temperatures, I hunt from 10 degrees up to maybe 60 or so, would this be the cold that would warrant LRM primer? I'm feeling like maybe I should pull the work up loads and go for WLR's.

Back when I was young, there was no weather too cold to hunt, shoot or fish in. That being said, it is rare very rare to have single digit temperature here in S. GA. I have shot LRP in the teens with out any problem what so ever with my 25/06, 243 & 270 Win(no longer have). Anything colder, you'll have to ask someone North that question.
Now days if it is below freezing, get my meat out of the freezer or at the grocery store.

Never in my youth did I understand how the older folks were always cold, I could never understand why some older guys peed on the tips of their boots.... but I do now!
