44s into 44mag

[monge]

Is it possible to convert a 44sp blackhawk into a 44mag ? Just want to shoot light 44mag loads out of it. Thanks Joe:holysheep

[PacMan]

Is it possible? Yes
Should you? most likely not. If you were going to live forever and be the only person to ever own the gun would be one thing. But we know that ant happening.
Having said all that i did somthing close.I reamed the cylinders of a 44sp stoping just short of letting a full length 44mag case fit.
Would i ever do it again? NO.

Flame away guys

light 44 mag loads = heavy 44 sp loads
from the dreams of one mans 44 sp spawned the 44 mag

[Char-Gar]

Not a good idea.

The 44 Special Blackhawk is called a flattop, the frame is lighter that the usual Blackhawk frame used for the magnums, only by a small amount but, enough that you wouldn't want to use it for that.

It would be safer to use a 44 Magnum frame as opposed to the flattop. I like my 44 flattop, it's really nice. It has become one of my favorite pea shooters now!

The frame isn't the problem, it is the diameter of the cylinder and the thickness of the cylinder at the bolt notches.

You are correct!

[Ed K]

Interestingly Elmer Keith wanted a gun and load that was in the vicinity of the heavy 44 special/ light 44mag that you speak of. What was placed into his hands was more than he had bargained for.

Anyhow since you can do what you want with 44 special brass why would you want to permanently modify your gun?

[44man]

I agree, nothing wrong with the special. If you want a mag, just buy one. You gain nothing loading light loads in longer brass.

[big dale]

This looks like the perfect excuse to buy another gun.

Have fun with this stuff.

Thanks for the help I think Ill pass on reaming cylinders . 44s is a pound lighter to carry eneyway!

The weight in the 44 Special Ruger is in the grip frame. Chang it to an alloy one if you are wanting a light packing gun. If size isn't a concern, get a 45 Blackhawk, blued. It is about the lightest Ruger has.

[KYCaster]

You can call me a wimp, but 44 Special is all the fun I can stand in a single action frame. :oops:

When I want to shoot a magnum it's in a more recoil friendly package.

You can call me a wimp,

No, sir, I shoot a 41 magnum, it can seriously dish it out!

[scattershot]

You can get within shouting distance of 1000 fps with the Special, so I'm not sure what you would gain by rechambering to a possibly dangerous cartridge. somewhere down the line, someone will stick a Garrett Abominable Snowman load in that pistol, with possible damage to the gun and the shooter. I wouldn't do it, and I'll bet a gunsmith wouldn't, either.

[MT Gianni]

You are better off trading for a Mag if that is what you want.

[Lloyd Smale]

in a ruger flattop you can get within shouting distance of 1200 fps with a 250 cast. Its a level i run most of my 44 mags at anyway. that said im a big 44mag fan and would love a 4 5/8s flattop bisley in 44 mag. My thoughts though go to making it a 5 shot so heavy bullets could be run a 1200 fps.

In a SPECIAL?? Holy cow!!!

[monge]

what are some of your favorite 44sp loads?

[Lloyd Smale]

ive shot a ton of 250s ahead of 18 grains of 2400 in my flattop. Ive even put quite a few of those loads through my 696 but anymore have backed that gun down to 1000 fps loads. It never gave me any troubles but ive allways been conserned about how thin the forcing cone is on it. Ive also got a 3 screw 357 that clements coverted to a 4 inch 44 spec and its digested MANY of those loads and has even taken a buffalo using them. The ruger mid frames are plenty strong for that load. Another good one is 20 grains of 110. Dont shoot these in a charter bulldog or a tarus though as they will certianly shoot the gun loose in short order.

[EDK]

UNCLE ELMER, patron saint of the magnums, ran 18 grains of 2400 in the old style ballon head 44 SPECIAL brass with 429421 in various COLT and SMITH & WESSON 44 SPECIALS for decades. When the solid head brass came out, he reduced the load to 17 grains. As was mentioned previously, the 44 MAGNUM was a bit more than Elmer envisioned....and he embraced it WITH some reservations. He wrote somewhere that he put 600 rounds of factory MAGNUM loads through the 6.5 inch Model S&W that was his first 44 MAGNUM in a year.

I don't hunt much, so I can use less enthusiastic loads. My preferred guns are 5.5 inch 44 MAGNUM Original Size VAQUEROS (with DRAGOON or HUNTER grip frames) or BISLEY VAQUEROS. Obviously adjustable sighted SUPER BLACK HAWKS/BISLEYS are a better choice for some purposes, but I like the VAQUEROS. My loadings are in the area that Elmer had in mind...perhaps a bit lighter. Some easier on the guns and my aging body.

Hey LLoyd, take a look at Jim Stroh's (ALPHA PRECISION) web site for his FLAT TOP conversion with the BOWEN target rear sights. He welds up the frame, re-machines it for the rear sight, etc. Beautiful workmanship from a guy who takes his work beyond craftsmanship into art work.

Having read in other places the loads that EDK reports, I figured 15grains under the classic 429421 would be a prudent place to start in my 4 5/8" FT .44Spl.

Must be some cold fusion going on or something because they clocked right on 1200fps and in that little gun are quite the handful!

13gr of 2400 will run these 240swcs right around 1050fps in my pistol and that's about all the knuckle of my middle finger wants to shoot.

[EDK]

The NEW version of 2400 is allegedly some hotter than the older version...don't know the cut-off dates/lot numbers, but its been a few years.

Pressure testing equipment and chronographs have been improved considerably since a lot of these loads were developed. There were a lot of "estimates" on pressure and velocity...Scientific Wild A** Guesses might be better!...back in the "good old days." Looking at published loads in LYMAN and other reloading manuals dating back to the 1950s/1960s is a good example. Loads have been reduced.

I got "my knuckles dusted" with XR3-red grip frames on 5.5 inch SUPER BLACK HAWKS and VAQUEROS, so I switched to DRAGOON/HUNTER grip frames on all of mine. No problem with the BISLEYS in that length. The SAA style grip is sadly lacking when you go for higher end performance; EAGLE GRIPS Gunfighter Model grips will help as much as is possible.

The various gun writers who praised the various "wrist wreckers" in the past seem to have re-dsicovered the 44 Special and 45 Colt in more conservative loadings. Load a little lighter and avoid carpal tunnel...your guns will appreciate it also.

Do you mean to say 15 grains of 2400? If so, your velocities surely are different than mine --- Really different.

In a Stainless, NM BlackHawk 44 Special, 4 5/8" barrel:

16 grains 2400 + 250 grain 429421 + WW LPP + Starline brass = 1060 fps

the 240 grain Nosler JHP with 16 grains of 2400 does 1050 fps.

[PWS]

Larry, you read the numbers correctly. Beats me why 2400 is so fast in this particular pistol as 700X, Clays, IMR4227, and Universal are behaving normally. Pressures are there with the 2400 too (according to case expansions) so I'm glad I didn't start higher! Here's a few more with 2400:

#429421, .430", 22Bhn, Lyman Moly lube, CBC brass, Fed 150 primer:

14gr - 1139 fps
13gr - 1103 fps

RCBS 44-240SWC GC, .430", 22Bhn, White Label CR lube, CBC brass, Fed 150 primer:

13.5gr - 1122 fps
13.0gr - 1053 fps

Cylinder throats are on the large size, almost .432" and I think the bore is a bit small .427" but I haven't measured it other than on recovered (and somewhat distorted) slugs.

I haven't tried a bunch of different bullets yet but the #429421 and the RCBS will group into 1 1/2" at 25yards pretty often. Not sure I need to look much further!

[PWS]

Sorry for the hijack of the original "44s into 44mag" post. Point being, the conversion may not be necessary at all!

[monge]

Is that 14grs of 2400 a compressed load ? Thanks Joe

I am getting 1140fps with 16 grains of 2400 in my BH using a Keith 150gr.

[PWS]

Not quite and 15grains was also very close to 100% load density. I'd planned on working upwards from 15gr but after getting 1200fps, I had to go down!

[1Shirt]

I guess my question would be "why would you need or want to to it"? To me a waste of time, and money. A good 44Sp works just fine, doen'nt need to be fixed.
1Shirt!

[monge]

Some people say 2400 doesnt like short barrels and unique is a better chioce what do you guys think? my two 44sp both have short barrels.

As stated above, I use 2400 in my 4 5/8" Flattop with heavy bullets. Especially with 250 grain WFNGCs, Power Pistol (a faster powder -- in the Unique range) won't give the velocity that 2400 does, at least in my gun.

I'd surely be interested in your results using a different lot of 2400 --- I've never seen/heard of velocities even close to yours.

It takes Brian Pearce (Handloader Mag) 17 grains of 2400 to get 1200 fps with a 250 grain 429421 in a 5 1/2"er.

[EDK]

Velocity can be effected by a lot of variables.

RUGER made a short run of 38-40 and 10MM/40 S&W? convertible BLACK HAWKS awhile back. Various gun writers reported EXTREMELY high velocity with factory ammo....they also mentioned that case expansion was minimal due to TIGHT chambering. Some research on the 38/40 shows a great variation between factory chamber and ammo dimensions...the case really gets altered/expanded when fired...then you overwork the brass reloading it!

My SWAG (Scientific Will A** Guess) is that PWS has a gun with optimal dimensions for velocity....AND accuracy sounds pretty good too.

:redneck: :cbpour: :guntootsmiley:

[Larry in MT]

EDK
I'm not trying to beat this to death, PWS surely knows of what he speaks:

but .... explain to me why only 2400 produces exceptional velocity figures for PWS while all the other powders behave normally...

I have a Rem 700 in 7 Mag that produces more fps than it should with reasonable pressure signs using IMR4831. Never quite figured out why.
