I am looking into trying some surplus powder for .223 and .308. So far I think wc846 is the ticket. The downsides I see are the differing burn rates from lot to lot. I did read that the wc846 is temperature sensitive, with performance similar to BLC2. These reloads will only need to keep "minute of varmint" accuracy inside 200 yards and I am not really interested in max velocities from either caliber. .223 will be used in a T/C Encore (rifle) and the .308 in a Remington 700 LTR, no gas operated guns. Any personal experiences (especially any negatives) loading with surplus powder would be appreciated, as would any other considerations I may be missing. At about 1/2 the price of what I use now (Varget, IMR 3031 and W748) I'd like to think the wc846 will work out. Thanks for any opinions.
