This will be quick as I am posting this via my blackberry.

I have an old lot of 38 special remington that had straight lead 158 grain round nose projectiles. The brass has a crimp quarter inch down from opening. Almost looks like a canelure in a projectile would.

What is the purpose that and should I even try to reload these cases, I.em, the grove in brass weakens brass?

Thabks boys.
 
Case cannelure.
Won't hurt anything, and will iron out over several firings.
It might eventually break there, but it's far more likely the necks will crack before that happens.

It was used to prevent any chance of a bullet getting pushed back inside the case on top of the very fast burning powder they used in them.

OK

I'm no expert by any means, but I've asked the same questions before and was told they're OK to use. I was told that was actually called a cannelure (just like the one on the projectile) and that it is there to hold the bullet in the case during production. What I pictured was that cannelure keeping the bullet from vibrating down into the case on an assembly line.

I've loaded several hundred rounds with cases like that with no problems...both in .44 mag and in 38 spcl...also to 38 spcl +P pressures.
 
I reload them all the time. IMHO Remington brass is thinner and tends to split the necks sooner than other brands. YMMV.
