Gang, I just purchased 8 lbs each of the above powders and would like to know if any of you have used them with good results. The WC 846 will be used in an AR15 with 55gr and 62gr bullets. Is 27gr a good load or should I start lighter and go up from there? WC 852 will be used in 7.5x55 and 6.5x55 (Swiss and Swedish rifles). Any proven recipes on these two will be appreciated. Thanks, gcp | ||

846, ended up with 40 grains in a 308 using 150 gr pulldown bullets. Shot very well in an M-1A. It made a big flash in 30-06, just not every time, very disconcerting. Did not use it in 223. Used 844. 852F, nice stuff mine loaded like Winchester 760. Made some very accurate '06 loads using 173 grain surplus match bullets. Mollied them and put 50 grain of MY 852 under them and used magnum primers. Work up slowly. You powder may be different from mine. I use expansion at the web as my yardstick. When the expansion is the same as the load I am trying to duplicate I figure I am getting simmilar pressure. Many here will debate that point. All I know is I get factory like velocities, primers look normal and case life is good. Best part is you can plot out the pressure rise and see it coming. | |||

Which batch of WC852 did you buy? There are three DIFFERENT batches out there and the load basis varies according to which you have. | |||

I have used a lot of 852 works well. The 846 I have is very hot I have to use 20 to 30 percent less or I really get high pressures. Be carefull with the 846 and start out low with it. I have blown primers with starting loads of 846. | |||

Quote: Get a copy of "Pet Loads" by Ken Watters. It is expalined in detail there. Basically the brass case walls are tapered thickness. The head is solid. The chamber is tapered. The higher the pressure the further toward the bolt head will the brass perminantly expand due to firing. You can measure the expansion at the junction of the solid head and case wall with a micrometer. You need to do this to 0.0001. Basically, measure the fattest part of the fired case. Measure factory loads and compare them to your reloads. Smaller equals lower pressure. Fatter equals more pressure. Use the same brass. | |||

Here's the lot numbers of the powders I purchased: WC846 #5106 WC852 #47287 Tomorrow I will try the 223 loads with a starting charge of 25gr and go up by .5gr increments to 27gr if possible. That's with 55gr FMJ bullets of course. I am shooting for 3,250f/s velocity max. scot I'll look up "Pet Loads", thanks. gcp | |||
