Quote;"I don't see much advantage in it for straight walled pistol. I tumble my brass and it goes through the resizer with very little effort in my Lee carbide dies. If you wnt a good lube, try RCBS case lube-2. It won't harm primers or powder, so if you want to use it on a progressive you won't have to worry about case lube contamination."quote
Wrong! RCBS case lube 2 says right on the bottle "NOTE Too much lube may destroy powder and primers. Wipe cases clean after sizeing".
On the other hand, RCBS case slick spray lube does NOT affect primers or powder. If you insist on lubing straight walled pistol cases, the case slik spray would work great. I use it when I'm loading .223 on my dillon 650.
