Quote from: TXCOONDOG on December 08 2019 06:46:39 AM MSTThe .357 Sig is a very accurate, hard hitting & flat-shooting round ... along with the 10mm & 7.62x25, it's right at the top of my favorite caliber heap.
...How accurate is the round ?
Anyone convert there 40 to the Sig .357 ?
Your favorite powders, etc ?
Likes, dislikes and other thoughts ?
All my 357s are actual .357s, save for an HK VP40 & Steyer L40-A1 which were purchased for the sole purpose of converting them to .357 Sig ... which I did, thanks to Rim Country Manufacturing & their excellent barrels. All it takes to turn a .40 S&W into a .357 Sig is a barrel & possibly, depending on how you & your pistol perform, a different front sight.
My favorite powders are AA#9 & 800X, the latter which, though it meters like a bag of Doritos, is one of the best kept .357 Sig secrets ... it affords amazing results @ diminished pressure levels. I go the two-step, lube-free route when it comes to sizing - i.e., I first run cases through a Redding 10mm carbide sizing die & then through a conventional Redding .357 Sig sizing die. Having experimented with a number of different bullets, I now load exclusively with Montana Gold FMJ & JHP 125gr .357 &/or RMR (9mm/.357 Sig) JHP 124gr Multi Purpose bullets ... both are excellent performers & have the perfect ogive for .357 brass. Yea, I quit pulling my hair out @ the bench once I started using those bullets!
