Hi all, I got a jug of WC 852 from Hi-Tech, lot# BAJ 47288. I loaded some up in my Mauser 06 in win case with REM 165 FLGC and CCI 200 primer. I got very low velocities.
52gns 2484, 2455, 2461
54gns 2414, 2382, 2139
56gns 2436, 2370
58gns 2480, 2507, 2419
60gns 2527, 2470
I was under the impression that WC852 was close in burn rate to IMR4831. It is a very fine ball powder.
I have shot 60gns RL22 for 2770 in the same gun. I also loaded 60gns of IMR5010 and got 2150.
I didn't use a mag primer. Would this help or do I just have a really slow lot of powder?

Lar, check the chrono with a KNOWN load to guarantee that you have a slow lot of 852 before going to smaller bores with the powder. ... felix

Sounds good, I'll do that today. I replaced the battery last night, but the old one was still 8v.

I checked the chrono with last years loads and it was the same. I tried some FED215's with 60gns today and it went up to around 2650.

Lars, now you know your 852 lot is a notch slower than RL22. Try circa 52 grains with a 180-210 grainer cast, seeking the accuracy spot. ... felix
