mikeAZ Posted October 25, 2015 Share Posted October 25, 2015 I've been a participant in the learning curve for the 929's (Have 2 of them) one with a C-More one with fiber sights front and rear. . Previously, I had 2 each 627's which had their own likes and dislikes. I shoot lot's and lot's of 9mm in various pistols, rifles and this was my main reason for the switch from 627's and short Colt ammo. If your NOT a big user of 9mm?, I see no big reason to switch to the 929 platform from the 627 platform unless you just want a new toy???.... To be honest, my ignorance and my insistence of what I thought I needed caused most of my so called 929 "sticky" cylinder issues (That and the "U" die loosening in my Dillon). Too much Clays didn't help either. I had the original moon clips EDM cut and insisted that they be on the "tight" side rather than the loose side for FEDERAL nickel cases, mistake #1. (It's 100% true that there is a big variance in 9mm brass). A little loose is better than a little tight. Of course, the 1st. thing I did was a little interior polishing/spring changes and added one Apex hammer and one lightened stock Mims hammer in the second, Apex firing pins in both. Neither 929 was way bad from the Factory, though the forcing cone in the 1st. one was not filed square (I squared it with the Brownells cutter/facer..... If the S&W 929's were sold for a lot less...... they would be a great buy.... (Dream on).. I've settled on Titegroup powder as it's fairly easy to get compared to Vit. or ????...Bullets, I'm pretty open, I'm experimenting with 124's,147's,160's, FMJ's, plated, coated.ONE very important thing,..... I gauge every round and the best $$$ spent is for the EGW 7 round checker (made with Clymer finish reamers). Trigger's are set to just a tic over 6#'s and Fed. 100 primers are used... I use the AA holster as I have the S&W and Glock insert and it's a 5 minute change when it's Glock time... You can read my beginning posts when I was more ignorant......I'm 74 years old and would be 75 except I was sick for a year.....Mike Link to comment Share on other sites More sharing options...
Ty Hamby Posted October 25, 2015 Share Posted October 25, 2015 (edited) Tagged. I am also working on 929 loads. I have 2 929's and both are showing horrible accuracy so far. I have been working exclusively with Short Colts with coated 160gn .358 bullets with both N310 and N320. I have some coated 145gn (135gn without lube groove) sized to .357 on their way. One revolvers cylinders throats 4x .3565 and 4x .357. The other cylinder throats are all 8 .357 using pin gauges to determine. I also used a plug guage to determine the forcing cone is within spec. I have re-cut the crown on one of the two. I really thought I would have found a load by now. I have tried 160's loaded 1.170 - 1.250 OAL and charges varying from N310 2.6-2.9 and N320 3.1-3.5 Looking forward to trying the 145's I have coming. I also have a couple thousand Bear Creek 170's sized to .356 I may play with. I have on hand lots of S1000, Universal Clays, N310 and N320. Time is ticking away. I need a load for short colts im my 929's before the 2016 season. Edited October 25, 2015 by Ty Hamby Link to comment Share on other sites More sharing options...
peterthefish Posted October 25, 2015 Share Posted October 25, 2015 It might seem crazy but have you tried some 9mm cases to see if that helps w accuracy? Link to comment Share on other sites More sharing options...
Ty Hamby Posted October 25, 2015 Share Posted October 25, 2015 It might seem crazy but have you tried some 9mm cases to see if that helps w accuracy? I shot some of my 135gn 1.100OAL pet loads from my CZ shadow. Didn't impress me enough to measure. All of my shots in testing are from a Ransom Rest with the trigger being pulled via a metal rod in each hand pulled equally rearward. All issues are ammo and mechanical accuracy of the gun.

The closest I came was a non-repeatable 1.25" a 30.. Average group was 2+"@30yds. hopeing to do better.

seanc Posted October 25, 2015 Share Posted October 25, 2015 Ive had OK results w .357 147 GR Blue Bullets and N320. Not sure what your standard is for accuracy. He is looking for sub 2" at 50 yards for ICORE, specifically far and near standards. I'd be happy with a 3" but 2" is gooder. I haven't found a definitive 3 yet, but I did find something very promising in hornady 147 HP/XTP that will be getting more tinking. Link to comment Share on other sites More sharing options...

I got some Zero 147 JHPs I'm going to try next, but with cylinder throats at .357 I'm not expecting much. Link to comment Share on other sites More sharing options...

dillon Posted October 27, 2015 Share Posted October 27, 2015 (edited) One of my customers had accuracy issues with his 929. Upon slugging the barrel, the groove-to groove dimension was .3565" . He switched to 130 grain 38 Super projectiles and a medum burning rate powder, and groups shrunk to acceptable levels. No 115 grain projectiles performed well at all, regardless of diameter.

Ty Hamby Posted October 31, 2015 Share Posted October 31, 2015 Update.I finally found some success in my 929's with Short Colts N310 and .358 160BBI's I just needed to shorten the OAL and back off the charge. Thank you Sean Cheney for the recommendations. Here are photos of my latest load and photos of the groups. Everything was @ 25yards with 160BBI's Loaded to 1.20OAL in Starline Shortcolts with 2.7gn's of VV N310. Link to comment Share on other sites More sharing options...
