.44 mag load needed

[Ghost101]

I would like some help for a .44 mag load. I've got a Lyman mold # 4296400V, 856 located below the main number. It's a HP,
GC boolit that should of been 250 gr., but mine are 274, with the GC an Felix lube, sized at .431. Was thinking along the lines of starting with 2400 at 18 gr. Shooting will be out of a early Ruger Vaquero and a Ruger SBH at 4 5/8 barrel.
I believe they are COWW. At the time I wasn't writing everything down like Im trying to do now. Trying hard to get this info stuff down on paper now so I know at a later date what I have.
So anyway If anyone has ideas as to what I should try, I'm all ears or eyes I suppose.

The Alliant 2400 max load datum for 270 grain jacketed bullets is lower than the charge you proposed.

Alliant data for a 250 grain Keith bullet are in line with your proposal.

I suggest buying a Lyman cast bullets reloading manual and work up your loads from that.

Tough to give solid advice on something like this because it is all going to depend on the gun. Try to make the best bullets you can, be careful with your loading practice, and try all kinds of loads from minimum to maximum. My best is a Saeco 441 out of an Anaconda with 8 inch barrel close to max with H110. I also have a Lyman with a gas check but don't know the number and I don't see it in my pile and may have loaned it out and don't remember. It however was not as accurate as the Saeco plus the Saeco doesn't use a gas check. My BHN runs around 10, I use soft lube, and I size to .428 and crimp on the groove.

Just saying, but why start out over max ? seems the advise to get a book or two is sound.

[Ghost101]

Oh but I do have the Lyman Cast Boolit Handbook an several others. The book suggests a 250gr starting load at 17.4 up to 19.2 of 2400. But being that this lot weights in at 274 gr., I want to ask before trying to load. If 24 gr. is not a deal breaker then I indeed will go with the 250 gr. loading data. The Saeco at 265 gr., with 2400 starts out at 18.0 gr., but the Lyman 300 gr. boolit drops down to 14.0 gr. of 2400. This is a stumbling block for me when the boolits are over weight to the listed weights and loading data. I'll get to that point, but not there yet.

24/25 grains could be a deal breaker and maybe not, DEPENDS.
Also it does not have to be a stumbling block of any sort. You can always take the next bullet weight up and work up the load from there, powders like H110 or 296 may be a problem cause they do not like to be loaded under book loads for a given bullet. But 2400 is not of that sort. When in doubt always ask and double chesk as you are doing, be safe.
If it were me and I had no one to ask I would use the start load for the 250 grain bullet you said that was
17.4 and work up a comfortable accurate load watching for over pressure. IMHO the max of 19.2 will be a warm load.

My hunting load is 19 grains of 2400 with a Lyman 429244 GC bullet, it drops about 255 grains and it is a warm load that chronographs at about 1350

I never just pick a load from the choices given for a given bullet weight and powder, I always work up my load from Min. to max in 2 or 3 1/10 increments looking for the best accuracy, most times it's not the hottest load.

Yes it takes more bullets and a few more primers and a little more powder, but it lets you maintain control of the workup.

Ifin it was me I'd start with the 14gr and go from there. You can always go up. In this type of situation I usually do 1/2 grain increases from lowest listed load on a heavier bullet to 1/2gr short of the max load with 5 bullets at each level. You can then track the primer changes to avoid an over pressure problem.

I shot some 244 gr GC 429244's last weekend with 18.6, 19.6 & 20 gr's 2400 All shot nice out of the 7.5" SBH. I like hot loads but I'll tell you what, the 244's @ 20gr felt as hot as most of the hot - jacketed bullet loads I shot. Primer were a little flattened (still a little of the round edges on the primer) and I might go 1/2 grain higher before chickening out. I decided I'd go with 19 gr and chronograph the load to see if they were up to par for my needs. But 24 gr with a 250 is more then I'll do. I like my hands and eyes too much. Be safe.

Mine cast at 263 gn with WW+2% tin. I have been using 22.5 gn Win 296 with CCI LPM seated to the crimp groove. I get excellent accuracy out of the Handi-rifle and a Ruger Super Black-hawk. The load is within the guidelines of the Lyman Manual.

[Grizzly Adams]

Look at all PUBLISHED data you can find (manuals and web) and make a
SWAG (sceintific wild @ss guess) but be conservitive. That being said, I would start
at 15.5g of 2400 and feel fine about it, but I couldn't say the same about 18g without
running a few lower loads through the particular firearm it was intended for. YMMV

[randyrat]

Check into some loads using Unique for some enjoyable shooting.
For "night fire" FUN you have to try some H110/296 out of the shorter barrel. You'll find a load using 2400 and chances are you'll never look back.

Go by boolit weight with just the GC on it, don't bother adding lube weight, makes not a whit of difference for the load.
You will be OK just work loads normally. Flat primers will not tell you anything either, the only indication of over loads will be sticky extraction and even then it can be hard to reach that point so don't even look for it.
Friends have used gross over loads in Rugers and brass fell out. One fella went 8 gr of 296 over max in the .45 Vaquero with no pressure signs, Kind of made me spit out my coffee when he told me.
It is not sane to keep loading, looking for pressure signs in a revolver.

My favorite is a 240gr SWC (3/4 jacket) over 23gr Win296/H110

[Shuz]

I have used 16g of 2400 or 17g of WC820(lot#47320) with the 429640PB or GC for many years. Both loads shoot very well and cases extact easily. Guns used are 629-3 Classic DX,2/ea, 3/ea Ruger SBH's, S&W 329PD, and a 629-4 Mtn Gun.

[44MAG#1]

I have a 270 gr Keith that I use and have shot 20 gr 2400 behind it for years. It seats no deeper than a 250 Keith from the various mold makers and that load works well.
When considering a load one must REMEMBER that seating depth is the major concern. A few grains difference in weight is not as important as depth of seating.
Standard primers are all I use with 2400.
Start at 17.5 gr 2400 and work up and see. You are the Captain of your ship not us. Unless you are looking for a pilot to take it out of port.

I also use the 429640HP and with my alloy they weigh, fully dressed, at 270 gr. I have pressure tested (Oehler M43 with Contender test barrel) 44 magnum loads with Alliant 2400 and found 20.2 gr to consistently be just under the SAAMI MAP (Maximum Average Pressure) of 36,000 psi. I have found 19.5 gr to be an excellent load and is the one I use with that bullet and 2400. I most often use H110 with this bullet in the 44 Magnum as it gives better performance at less psi. However, if 2400 is what you have and what you want to use it will work very nicely.

In the old days with my BH flat top I used Elmers load of 22 gr of 2400 and the 250 gr 429421 all the time. Would I do the same today, darn right I would.

That is still my standard load under the RCBS 44-250-KT and an excellent one it is. Out of the same Contender pressure barrel it runs 33,800 psi(M43) and 1462 fps out of my Ruger 50th Anniversary FT.

I started a 16 gr w my mihec 272 gr hp. I worked up to 18.5. no pressure signs there, howeber, it was not as much fun nor as accurate as 17.5 grains. I'm staying there. lol

[kweidner]

When you get upwards of 19gr you will know it in a 4 5/8. Although accurate, it's not something I want to shoot all day everyday. 2400 has a pretty steong recoil pulse. I use 2400 for hunting rounds and have loads with unique for enjoying.
