Mag Primers Required For WC820?

[alamogunr]

Did a quick search but found nothing that addressed this question directly. I normally use WLP with my low to mid-range loads in .45 Colt and .475L using HS-6 and Unique. I think I'm ready to move up to some higher power loads(not max) and I have a lot of WC820 on hand. I would prefer to continue to use the WLP but will buy mag primers if that is the reommended way to go.

I'd say no they are not required. I've switched from magnum primers to WLP for my H110 loads with no ill effects. They actually may be a bit more accurate than with the magnum primers. I still use the magnum primers in some of my 45 Colt loads simply because they are silver. Reason being, it is one more way of differentiating between rounds that are safe for my Uberti and Mid Frame Flattop. Any of my 45 Colt loads with the silver CCI primers are not to be shot in the weaker revolvers. It's simply an extra precaution to keep Murphy from paying a visit.

Some guys on the castboolits forum say yes to mag primers, but if you have good case/bullet tension, a firm crimp with proper load density the WLP should work just fine.

I use mag primers with H108 (said to be similar to WC820), but then I've got a bunch to burn up.

A guy on another forum said that he had squib loads when shooting WC820 at very low temps, even WITH mag primers. Squibs in that they fizzled, and lodged the bullet into the forcing cone or bore, along with a clump of unburned powder. The loads were supposedly normal charges. He's an experienced reloader and shooter, so I'm inclined to believe him. This might be something to watch out for if you hunt in the cold.

I have burned 24 lbs plus, working on my last jug ,and wish I had bought more. Lots may vary I suppose. Mine mirrors AA#9 across the chrono and on target. Never had any issues with primers or cold weather with my lot.
Kilauea powders I think should be approached with the ide some load work will need to be done. More so than a regular off the shelf powder.

I can be a bit dense, but not sure what this means -- can you clarify?

Thanks,

My lot of WC820 has an identical burn rate to AA-9, I have only used standard primers. Some lots of WC820 are closer to H-110, I don't have any experience with those lots.

As far as I can tell, the surplus powder has lost it's value for being a cheap reloading component. Between the lack of availability, and increased cost, canister powders are almost just as cheap, and more readily available.

Our testing with wc820(lot 47320 and 47321) in a ballistic lab shows the federal 155 is verging on dangerous swings, the WLP current is not so good either. Remington 2 1/2 and cci300 both were pretty good. This is 45 colt, 310 Keith data. Large pistol primers are very different from each other.
The federal 155 in my 44 mag is pretty good or at least without the pressure swings as in the 45.

Kilauea, I have no idea how spell check came up with that......... Lol I typed in surplus again and it tried to put that down.
Should have been surplus powders.
