Sig 229 w/ CB's

[gembob13]

I've read a lot on here about CB's being a bit 'unlucky' in some .40 S&W semi-auto's, especially Glocks. I have a Sig P229 and so far it has fed anything I've put through it. I'm just wondering if anyone here has a 229, or a sig in .40 and what molds work well for it or if any of em will do. PS I did do a search for this, thanks in advance.

Lee 6 bangers or RCBS 175 gr 2 cavity in 10mm are the recommended diet. I have a couple of 229's with 357 sig as well as 40 cal barrels. To add to GemBob's question, if anyone finds a good cast boolit for 357 sig that has lots of room for the taper crimp so it doesn't slide back into the case for the 229's, please let me know what you are using. oh....if it shoots really well, that would be good too. :drinks:

I run the 175 gr ( standard lube grove ) Lee 6 gang mould in my 229

Mine will also feed just about everything

I had to drop to close to start loads to get mine ( night sights ) to shoot close to POA
I wanted to try a 200 gr bullet to get the POI up
But so far the 175 gr bullets shoot so well I haven't bothered

+1 to the Lee 175 TC with conventional lube groove in the 40 S&W. No personal SIG-Sauer experience in 40 S&W, but this bullet did/does very well in a Beretta 96 and CZ-75B so chambered.

Aren't neck-and-shoulder autopistol cartridges FUN TO RELOAD? "My name is Allen, and I reload 30 Mauser and 30 Luger........"

Have you tried any of the truncated cone 9mm boolits? The Lee 122 grainer comes to mind here, there is a LOT more front drive band to set that taper crimp into than the round nosed designs incorporate. I've thought that an 85-90 grain version of such a design of .311" dimensions would do well in the necked monsters I reload. I do believe the greater bearing length of the TC's seems to grab hold on the quick-twist rifling in 9mm and 40 S&W barrels more readily than the shorter RN bearing lengths.
