I got some 160gr Blue Bullets, want to work a load and am looking to see what you all are having luck with. Right now, I have a 147gr Blue Bullet at 1.17 oal, Crimped to .177, Federal SPP, 3.3gr Vectan 9.5(about the same as VV 320), PF 128. Forgot, the bullets are 38/357 Kinda surprised how many folks use 160's in 9mm revolvers. Whats the 929's twist rate compared to typical auto ? My googlefoo is weak today. At sub 130 pf I have had some autoloaders that tumbled 147's. Link to comment Share on other sites More sharing options...

The barrel in my 929 is exactly the same as the barrel in my 627, both of them slugged at .357 Link to comment Share on other sites More sharing options...
ysrracer Posted May 29, 2023 Share Posted May 29, 2023 In my 627 I use a 160gr Bayou Bullet, in my 929 I use a 147gr Blue Bullet. No special reason, other than I use Win 231 in my 9mm and Clays in .38 Short Colt. Link to comment Share on other sites More sharing options...
tomjerry1 Posted May 29, 2023 Author Share Posted May 29, 2023 I believe it is a 1/10 twist rate. Link to comment Share on other sites More sharing options...

The barrels are both .357 but the factory barrels have a 1/16 or 1/18 twist as you mentioned. Apparently the aftermarket barrels are 1/10. At least that is what guys say here who have them.
