View Full Version : Do I need to remove sealant in case mouth?
August 13, 2001, 18:00
I acquired about 300 pcs of 7.62x51 berdan primed cartridge cases (mostly L2A2, some H, H1, H5)that someone had pulled the bullets from. The primers are OK. I cleaned up 10, loaded them with ~43 gr 748 and 147 gr FMJBT and they shot ok. They all have a tar-like sealant in the case neck. I had removed it from the 10 that I tested with q-tips and mineral spirits but I'm wondering if anyone has loaded any 'pulled' cases like these with no resizing or sealant removal. Any advice would be helpful.

I've been reloading for 30 yrs. and never encountered this. The sealant is inert, and they are Berdan, so as long as the bullets readily seat why bother? It won't affect chamber pressure, velocity, etc.. I'm sure what little might go in the bore won't
create any build up: think of it as bullet lube, which doesn't harm guns.

Hey; I have reloaded about 400 of the berdan cases & shot several of them ,and I have not noticed any ill effects from not cleaning them out. I just run a burring tool inside & out and dumped the powder in. So far So Good :) Thumper
