jh9 Posted March 5, 2015 Share Posted March 5, 2015 I'm thinking about having my 627 pro converted to 9mm. Mostly out of annoyance of having to transmogrify my 9mm and .38spl 550 toolheads every time I want to load it. That and I never did buy a *lot* of .38 short colt brass while I'm otherwise swimming in 9 and .38. Is there any reason to believe that having a shop like TK Custom do the conversion will get around some of the factory 929 issues (extraction issues specifically)? Is this a stupid idea that I should feel bad about saying in public? Link to comment Share on other sites More sharing options...
Toolguy Posted March 5, 2015 Share Posted March 5, 2015 It would be easy enough to ream the chambers for 9mm, you will probably have to load .357 or .358 bullets to get accuracy. It shouldn't work OK. There are a lot of variables, so impossible to say anything for certain ahead of time. I made 2 of my 686s into 40 S&W and they both turned out fine.

DougCarden Posted March 5, 2015 Share Posted March 5, 2015 Only thing I would add is you could Taylor throat your barrel so the bullet centers up when it engages the rifling, so you don't have to worry about the cylinder throats. I made a short colt only revo and it works just fine.... DougC Link to comment Share on other sites More sharing options...
revoman Posted March 5, 2015 Share Posted March 5, 2015 (edited) Same as Doug and it will keep them under 2" at 50 yds. I probably should have cleaned it. Edited March 5, 2015 by revoman Link to comment Share on other sites More sharing options...

crotchThrower Posted March 5, 2015 Share Posted March 5, 2015 (edited) Have you heard of the long colt? Scrap that, oh how about short colt..?. All can get you to the 125 PF and all you have to do is buy brass and dies... Don't do it! Edited March 5, 2015 by crotchThrower Link to comment Share on other sites More sharing options...
seanc Posted March 8, 2015 Share Posted March 8, 2015 i read a lot of mized results with these conversions, some reports are its the greatest thing since ever, other are that there are some issues. I was going to have an extra cylinder I have cut for 9mm so I could have a backup for my 929 but bailed when someone who had done this indicated he was loosing 100+fps on a converted gun vs his 929. No point if I can't have the same ammo. In order to compensate, my ammo would be like 150pf out of the 929 to make a comfortable 130 in the converted gun...

Toolguy Posted March 8, 2015 Share Posted March 8, 2015 When doing a convertible you have to make the cylinder gaps the same. Most revo velocity variations are cylinder gap, all else being equal. In reality all else is never equal, but you can get close enough to be workable. A different barrel will affect velocity too. Link to comment Share on other sites More sharing options...
DougCarden Posted March 9, 2015 Share Posted March 9, 2015 To Clarify with Short Colt.......You can load minor all the way up to Major...yes, it has been done....not sure why, but a European competitor did it. What you CAN'T do is use fast powder with heavy bullets and go over 128 PF without sticky extraction and problems. Using medium powder and you can run 135 PF + all day long with accurate and light recoiling ammo.....thread drift back on DougC Link to comment Share on other sites More sharing options...
crotchThrower Posted March 9, 2015 Share Posted March 9, 2015 Going over 128 PF when all you need is 125 is a moot point. No? Link to comment Share on other sites More sharing options...
Guest Posted March 9, 2015 Share Posted March 9, 2015 If you are running 160 grain bullets a 128pf only give you a 19fps cushion when you hit the chono stage. Making minor isn't a sure thing if you get a slow chrono, and if you fall below minor...well, hopefully you are having fun 'cuz you won't get scored.

Carmoney Posted March 11, 2015 Share Posted March 11, 2015 Going over 128 PF when all you need is 125 is a moot point. No? Personally, I would never attempt a big match with ammo that didn't hit at least 133 p.f. All my ammo hits at least that power factor in all my guns. Takes down steel, and I don't have to sweat chrono. Link to comment Share on other sites More sharing options...
MWP Posted March 11, 2015 Share Posted March 11, 2015 133-135 is the smart number for majors. 128 is fine if you don't mind shooting for no score at some point. Link to comment Share on other sites More sharing options...
jhgtyre Posted March 11, 2015 Share Posted March 11, 2015 My 160gr short colt loads make 137pf. After chrono I got a shrug and "I can't believe THAT made power factor" (or words to that effect) from the chrono guy. Link to comment Share on other sites More sharing options...
crotchThrower Posted March 12, 2015 Share Posted March 12, 2015 (edited) do you mind sharing or pm'ing your load for the short colt. Also isn't ICORE minimum PF 125? Am I mistaken? Edited March 12, 2015 by crotchThrower Link to comment Share on other sites More sharing options...
revoman Posted March 12, 2015 Share Posted March 12, 2015 ICORE is 120 PF Link to comment Share on other sites More sharing options...
girphoto Posted March 13, 2015 Share Posted March 13, 2015 So, I sent my S&W 67-5 to TK Custom and had them recut from 38 Spl. to 9 mm. The cylinder came back today, I took it to the range and out to 25 yes. shot 36 rds (6 clips) The result was not bad.....I load a 130g Berry's with 3.9 g Clay-Dot and Federal primers. It gives me a 123 PF. Link to comment Share on other sites More sharing options...
MrDanCheck Posted March 13, 2015 Share Posted March 13, 2015 I have 2 627s that where converted to 9mm by TKs.. Well worth the money. I run 38 super bullets and don't have any issues.. I just got a 929 and are wading through that mess now.. Link to comment Share on other sites More sharing options...
jh9 Posted March 13, 2015 Author Share Posted March 13, 2015 (edited) The only reservations I have are factory ammo making major (4" barrel in the 627pro) and factory bullets' (.355") accuracy at longish distance. Reloads would be using proper size lead, but part of the appeal is using factory ammo when it's available and I'm too lazy to put the press back together (live in an apartment) for loading up another batch. Anybody got rough chrono numbers for factory ball? I'd be plenty happy with girphoto's accuracy if those are .355" bullets.

girphoto Posted March 13, 2015 Share Posted March 13, 2015 Hi jh9 The bullets that I use measure 355.5 I just got a large order of lead at 354 and after loading a few moon's I will test on Saturday after our Cowboy Match. If I have time I will Chrono it. Load is 4g Clay-Dot, Federal primers and 130g lead (at 354) I will shoot at 25 yds to keep all the same. Link to comment Share on other sites More sharing options...

Bwana Six-Gun Posted March 16, 2015 Share Posted March 16, 2015 Where were you able to find Short Colt data for VV. I checked their website and could not find any. Do you get any pressure signs with this load? Is this a minimum, mid-range, or near max load? Appreciate the help. Link to comment Share on other sites More sharing options...
alecmc Posted March 16, 2015 Share Posted March 16, 2015 Use 9mm load data Link to comment Share on other sites More sharing options...
