Bullet is the NOE 260-118RF in plain base.
Powders are Smokes traffic purple and Smokes flat black.
Both covered very well, at least as well as the RCBS 25-120 that doesn't lead, but used a gas check.
Load is 12g of 2400 and WW large rifle primer for std or mag.
The NOE flat based bullet leads profusely, but the RCBS 25-120 gas checked does not.
Why?
