Grease groves?
My cast .358" bullets have two groves. One wide one close to the base and a narrow one closer to the tip. Are both channels grease groves? Or is the bottom one a grease grove and the top one a cannelure?

That is a poor pic of a crimping groove.

That`s an early likeness of a crimp groove (#1) nowadays the crimp is more beveled.
Here`s a link http://www.handloads.com/articles/default.asp?id=24 Good info by Mr. Fryxell `bout how the swc has changed & who designed em ! 1 of my favorite is the 358446 & the 358429 & the 358156 barebottomed & a couple of custom molds . Lee has some excellent designs the 105 gr swc for cheap plinking a 140 with the same profile,The 158 rnfp (it is hard for me to get this 1 to shoot bad & the only 6 banger I own) the wide meplated swc Gas Checked

Wow, awesome article! I need to read more of Glen's stuff. Many times when I read one of his articles or books I bookmark or print it.

I never relized that the 429421 & the 358429 are the same length & Elmer Keith would`nt budge on the design as most 357 magnum revolvers cyl. were too short at the time ,but in the end he still surmised that 173grs. was a bit heavy for the 357 & it shows on longer shots.
