Ruger Six cylinder gap (big flame)

[Mark_Mark]

What’s a acceptable cylinder gap for a Ruger Security Six?

I was testing some warm, Max Published .357 and there was some really big flame coming from the gap. My chrono ran out of battery so I don’t know the speed.

load data:

6.3 grain of Universal
158 grain Berry Flat Point
SPPM

.004 to .008 with .006 being best. Thank me for googling it for you.

I’ll measure when I get home

 

[357 Terms]

6.4 grns of Universal and a 158grn plated bullet (Xtreme) has been my 357 plinking load for years now.
I don't have my notes handy, I moved recently, hate moving, lots of stuff still packed away.
If I recall correctly my chrony clocked those at around 1100fps from a 4in Service Six.
I've shot 10,000 plus of those rounds from many 357's, I don't ever recall a huge blast/flame from any of them.
Certainly not compared to 296/H110.

Mark - you're lucky. The gap on my GP-100 is 50% larger at 0.009". According to the rep I talked with at Ruger, that is the max gap allowed out of the factory. They wouldn't do anything as it was still "in spec".

Sometimes a load is “flamy”, its just part of the revolver experience.

Mid-range load with Unique from a 4” S&W Model 66-1.



H-110 load from s 4” S&W Model 686+.





If your B/C gap is within the acceptable range, I would leave it be.

Stay safe.

that’s exactly how flaming my loads were!

just measured… between .006 & .007

I guess it’s a flambé load then, no pressure signs on the primer or case???

The fireball is just an added benefit of shooting revolvers... My 44 redhawk will make the front of the gun disappear in a fireball with my bear hunting loads...

Just make sure none of your digits are too far forward and you will be OK. Otherwise it's going to involve blood and pain. Many, many years ago I learned my lesson by not paying attention and got my finger scorched a little by a single six revolver. Really no damage but it tought me to pay attention to how I placed my left hand.

People have lost fingertips from that flame from 460, 454, and 500 revolvers.

Yeah, the current trend of crawling the support hand really far forward, as the current high speed/low drag guys do, can have bad consequences if shooting a revolver.

My Colt Open Top replica, even with nothing but full charge wadcutters, puts up an entertaining flash as a .38 Spl.

my 460 is no joke and demands your full attention!

Hmm. That doesn't look like it should be a problem, though the shooters left index looks a little dirty. Even a Chiappa bottom chamber revo doesn't bite me, though it does have a clever deflector built into the frame. My alloy frame Smith revos have a steel guard above the cylinder gap, to prevent flame cutting.

It's pretty much the grip I use. No hot fingers with it. The pictured hands are much larger than mine or that is a tiny Ruger. I'm going to say it is lighting and not a dirty finger to be nice.

Thanks. So it was pretty flashy then. Shooting .357 max loaded 125 gr indoors is a real blast in all ways

was not like shooting .38 HBWC!

But I like the load, recoil was mid to low. .357 is a beast round! btw… New to .357 & .38

 

[Laphroaig]

You got me curious and I checked mine. .005 slipped in easy, .006 was a little tight, and .007 wouldn't go.

I haven't shot mine recently; have to rectify that! .38/.357 is one of my favorites to load.

Most people these days have only shot Automatics. Different way of doing things. Hell, give 'em a Luger and they become confused too.

Lugers are confusing! but the look is 2th to the C96
