Reason I mention it is it has turned in (by less than .1") the best 25 yard group yet registered from my 6" Most jhps do 1.1-1.5 or so inches.
 
I will try once more to upload a picture. The system will not allow me to edit or delete the post.

I've been giving serious thought to switching my carry round from CCI Gold Dots to CorBon 110's, but those 140's look pretty impressive.
 
heres how those 110's stack up in the above rugers:

2.25" sp 101= 1466 4" Gp 100= 1635 6" GP 1725

I thought they must have gotten their advertised velocity of 1500 from a 2.5" but Murbach told me it was a 4" GP just like mine. They don't have much kick in the sp101 and cases fall out without even a nudge on the ejector.
 
Thanks mec...
Looks like your 6 incher fell in love with that load.

My experience has been that Cor-Bon's velocity statements have been on the conservative side. I like their stuff.

From a 6" or even a 4" barrel, a 140grain sounds great. Dunno if I'd want those out of a 2" class, I'd be concerned they wouldn't be driven fast enough to open well.

But ya, if your gun likes it and your follow-up shot speed is OK in your gun and arm muscles, go for it.
 
The 110's have (by the #'s) around 525 FPE from a snubby? HELLO!!! :D I think Im going to the store and get a couple of boxes. If they shoot where I want them to..I may have just found the best round for my pocket gun....Thanks Guys, I love this place.
Id have to agree on the published velocities being on the shy side from Corbon. Example...from my K40 the 135gr Corbon clocks at over 1270 FPS..on the box its rated at 1310 FPS...my little 3 1/2" tube almost does that. Not bad for a mini gun.
Shoot well
 
Actually, that 1225 from the sp101 is about the same as a lot of factory 125 grain loads do from the same gun. I would expect some sort of expansion from these. The 110 grain jobs shoot lower than the other ones but fired into a stack of beef brisket, they expand with fragmentation from the 2.25" bbl.

I've always gotten higher velociites than advetised from corbon- if only by a few feet per second. The 135 .40 sw does just over the advertised 1300 fps and has done this one several separate occasions. Everybody's gun,chronograph and local conditions are different and the surest way to never know exactly what is going on is to get two chronographs, two different guns or even sometimes, clock the same load twice.
 
I have a 27-2 that routinely turns in 1" groups at 25 yds with the Rem JHP 140's backed by 15 gr. of 2400. My velocity is slightly less than what you're getting in your 6" Ruger (mine also has a 6" barrel). Strangely this revolver does not shoot well with lighter loads and is terrible with .38's. I also have a 158 gr cast load that squeezes almost 700 ft/# from the Smith and it is almost as accurate as the 140's.
 
My experience with 27s seem to be that they tend to be ammo picky.
TERRY Murbach and I were comparing 27 notes a while back and he has seen the same thing. Absolute tack drivers with the load that the individual gun likes. Only good with other stuff.

sounds pretty normal. the gps have some load combinations they dont particularly like either. Same situation as you describe with model 27s. I had several loads shooting in the 2.5" at 25 yards region then tried some old lyman 358429 hollowpoints loaded over 2400 in 38 special cases and the groups shrunk down to just over an inch.

the 6" ruger hates 158 grain cast swcs over 3.5" bullseye if they are loaded in 38 cases. The 4" gp likes this load just fine and the 6" becomes accurate with the same combination in magnum cases. There are some .38 special case loads that it likes just fine.
 
My 357 redhawk doesn't seem to agree with anything lighter than a 158 grain slug. Yet my sp101 eats 125 grainers all day long with astounding accuracy.

This is one reason reloading is so rewarding.
