I'm looking to load up some .223 with 55 grain FMJ's. The WC 846 jugs I have say to use BLC2 data. My Speer manual calls for magnum primers with BLC2. Has anyone found it necessary to use magnum primers with the WC846? I didn't find another listing calling for magnum primers except Speer.

Thanks,

Dave

Dave, can't tell ya about 846 or BLC2. I've been using 2230-C (load like AA2460 which is right next to H335) in .223 with 55 gr Midway Dogtown bullets and they do just fine. Primers are small rifle. I've seen listings for H335 for mag primers. I say, if you can make a load work with standard primers, better.

.................I've used lots of WC846 in 223 out of my M112 Savage with std Win SR primers. No magnums. Ditto, partial to full caseloads in the 35 Rem under 200gr Saeco's. No magnum primers. I don't see how mag primers could have tightened up the groups I got.

Long ago I'd heard it said that if you go to a ball powder use magnum primers. I don't know if that was because the ball propellants had more deterrant used or if it was because they loaded denser? If you check castpics load data for surplus, any marked as "Buckshot' were all loaded with Win Std primers, either rifle or pistol. I think the only magnum primers I used was with WC820 in the 357 magnum. And that was only as I was doing direct load for load comparisons with H110 and W296 and they used mag primers.

I'm currently experimenting with WC846 in my 7.62X39 Remmy 799 and it appears you can't put enough in the case to get yourself in trouble. I started at 28 grains and worked up to 32 grains without any pressure indications. I'm currently using a magnum large rifle primer but I will switch to the standard as a comparison. Best grouping with 130 grain J words (until the barrel is broken in ) ran a true inch for 5 shots with 4 in a .436" cluster.
