24.0 grs H-110, 240 gr JHP is my standard load for my Redhalk. So you7 are fine.

I have gone as high as 25.0 grs during my long range (200 Meters) Sillouette days. I don't load that hot anymore.

One advantage of a Redhalk is that if a bullet has 2 cannelures, you can seat to the upper cannelure and gain case
capacity/increase powder charge. Work up carefully.

Talking about the 300 gr jacketed bullets, and the 310 gr powder coated bullets I cast.

My buddies Super Blackhalk won't chamber my long loads, cylinder is too short.

Back issue (couple years ago) of Handloader Magazine has loads for 44 Magnum +P.

I rarely chrono anything. Ever notice I never post velocities?

I remember reading the article, that's all.

Try a search on their website.

My Redhalk is magnaported and the hot 240 gr loads feel like shooting a 357.

The 300 gr full loads are a bit more, but don't cause me to flinch.

I highly recommend getting it done.

Wheel guns are pretty easy to monitor the load.

A. Make sure that the spent case are easy to hand eject out of the cylinder via the ejector.

B. take a look at the spent primers.   In 44 mag, your hot loads will require mag primers, the cups on the spent primers will show the correct pressure and so long as your spent primers are not flattened all the way to the side of the case primer pocket, your golden.

So primer in the middle and the spent case hand cycle out of the cylinder, your good.
Mag primer to the right, and even if it the cases  hand eject out of the cylinder with no problem via the ejector, your over max working pressures.



Now the last thing, just because you can get max speeds out of a pistol, does not mean that the bullet is going to shoot it best at those speeds.  So work up the load, find out where that bullet type shoots it best during increasing the speeds, and call it good for that speed.

Some good advice.

Yep, sticky extraction means load is too hot.

Some guns will handle hotter loads than some others. Which is why we test.

Trust me, on some of the hunting loads for my 629, they are not over pressure, but via long loading, well above the 1600fps mark while still in working pressures.

Simply put, on most 44 mag wheel guns, the cylinder gives you lots of room to long load the round to increase the working volume of the case under bullet set, and works best to use it to your advantage if speed is what you seak.




In a 1894, can push a 270gr hard case PC load COAL with .003" jump to lands, past the 2KFPS mark safely, but load that one back down to 1800fps since the rigs will shoot tighter groups at the slightly reduced load isntead.

To give you an idea of the increase in working case volume after bullet set, both the 270gr bullet on the left, and the 210gr bullet on the right have been seated in the case for the .003" jump to lands.  The bullets next to each case, show the increase or decrease of working volume if they were seated to different point on the case isntead.
Note, can get the 210gr well past 2500fps in the 1894's within working pressures, but has too small of a tip flat point to be useful as a hunting bullet and lets face it, just way to fast for any useful purpose in a heavy type bushing rifle to start with.

phdog, all the spent primers you show, have the ammo within working pressures.

As for max loads in the data, remember that that is for the components listed in the data, and more so to the COAL they show with those components since it for the give case volume amount under bullet set. By longer loading than the given COAL, your increasing the working volume of the case under bullet set, which allows you to increase what will be max charge.

But to back it up, can pretty much tell when you are going over pressure with a wheel gun, since the spent cases will be hard to eject to being with.  Looking at the spent primers next in the cases, just confirms such when the sides of the primer cup have pressure flowed all the way to the sides of the primer channel in the case.

H110/296 (they are the same powder, hence St marks #296), does not do well in 357 until you step up to a much heaver bullet over that of the 157gr type bullets.  Its just that the powder burns too slow for that light of a bullet, and will find that you can get faster speeds in 357 with powders that have a slightly faster burn rate instead.  So for say a 357 mag, 157 jacket bullet, will find that you achieve the highest speed from say a 6" barrel using something in the #7 burn range isntead.  Yes, #9 powder shows a increase of 6 FPS, that is requiring an addition 3 grs of powder.

In 44 mag, 240gr ~ 290gr, the H110/296 is an ideal burn speed, and why it pretty much the speed king for that caliber/bullet weight instead.
The downside through, is H110-296 needs at least 80% case volume fill under bullet set to maintain a reliable ignition, and the powder will produce it lowest SD right at max pressures.  So H110/296 is pretty much at go for max speeds/pressure kind of powder, and if your looking for a powder that has a wider range of pressure use/ not so sensitive, then use AA #9 or 2400 instead.

As for if going to a 300gr bullet or heaver, then you looking for a slightly slower burning powder instead.  Since I bring up St marks powder, 300-mp is produced by St mark as well, and has a burn speed of #297 instead.

Hence AA#9 has a burn speed close to St mark #295.
H-110/296 has a burn speed of #296 (since that is what the  powders are, just sold under different labling).
Since  Alliant could not get in on the band wagon to sell #296 powder under their own branding from SMP (Saint Marks Powder), they pick up one of the St marks #297 derivative powders, and 300-mp has the burn rate of #297.

__________________________________________
As for why Hodgdon and Olin/Winchester both selling the same SMP #296, before Olin starting selling powders to the public/reloaders, Hodgdon went to Olin to buy up surplus powders to get the company started, and at the time was a great deal of #296 surplus powder from 30 carbine mil loads that was available. When olin got into the market of selling canister powders to the public/reloaders later, since they owned the St mark plant at the time that was producing the powder, was able to offer the #296 under it own branding since it was not a breach of contract with Hodgdon contract.

GD bought the St mark plant some time ago (needed for the LC plant contract when they took over, since st mark plant is the only one making "Ball"/sperical powder in the states), and since olin/wichester type powder licensing where up for sale at the same time the plant was sold (which General Dynamics/ATK did not want since they focus on the goverment supply side only), Hodgdon bought up the Winchester powder licensing rights instead.

As for why I bring this up, both the H110 and Win 296 powders are both the same powder, sold by the same company now, and when shopping for such, just buy the one that the least expensive of the two isntead.  For the most part, will be the H110, since Hodgdon adds a small charge  to the win 296 branding of the powder, to pay for the additional licensing Fee to selll the powder in the Win labeling isntead.
Note: not a hard fast rule, since price is really dictated by the final shop selling the powder in the end, and have seen win 296, priced less expensive then H110 in some shops isntead.

With the faster burning powders like Unique or Unversial (both have close to the same burn speeds), these powders are used for med loads speeds, but you still have to watch the over all working pressures since these powders will spike very quickly isntead.

So at 12.5 grains of unique behind a 240 jacket bullet, your not really pushing anywhere close to max speeds, but well over the working pressure of the round to put undue stress on the parts that way instead.

Note, in the above data, the powder listed are by burn rate, and the slower the powder burns, the more of it you can use to increase the speed of the round, while the ammo's working pressure is not going over pressure.

As for the 629, its no where near at strong as the Ruger action, so using data at full speeds with the correct slower burning power, limit the bullet weight to 240gr max.  Bullets heaver this this, will really decrease the time before the 629 will need to be sent back in to be rebuilt.

As for the strongest action on the market for 300gr+ bullets at full speeds with the correct slow burning powder fr 44 mag, it was the Dan Wesson M44 with dual lock up.

St marks #296 and #297 are good powders for 44 mag with 240gr bullets or slightly heavier, but in 357 with a 157gr bullet, bullet is moving too fast/not enough weight to it to take advantage of power that is burning this slow for even a 357 mag with 8" barrel.

Now in a rifle with 16" barrel in 357 with a 157gr bullet, hell yes, since you have enough barrel to take advantage of the slower burn time isntead.

In 410, I hit 1350FPS with either 296/H110, or 300mp (#297) through 30" tubes,  and one power really does not top the other since both require about the same amount of powder volume to hit the same speeds. Here, your dealing with much less working pressures, plus you do have the limited room in the stack height to push the shell any faster instead.
Note, I'm loading on PW's, so the sizer fully contains the hull sides during sizing, does allow me to use a touch more powder, and not have the sides of the hull budge out during crimping if loading on say a Mec.

As for if you loading at less than 1300fps, then the 300-mp is not the ideal powder, and your better off with the slightly faster burning 296/H110 that will have lower SD's instead.

There are a couple different type ST marks #297 powders (flash suppressor or not), all though the 297 powder all have the same burn speeds,  Alliant has admitted that although the powder is not the standard WC 297 formula with flash suppression, but still St marks powder and does have the #297 burn speed ( slightly slower than WC 296).

I have some 296 loads that are 24.7gr with a 240 jhp.

No pressure signs in my Redhawk, but they are not pleasant to shoot

Ditto, big fan of Universal powder for 44 mag med speed pinking loads, since I burn it by the 8lb jugs in 20 and 28 gauge  for skeet to start with.

As for full loads with H110-296 via long loading so you can gain some speed without going over pressure (remember, this powder will have it lowest SD at max pressures), they are pretty much brutal to shoot no matter the rig.  In pistol, lets just say your not going to make a day of it at the range with such loads, since hands and wrists are going to be ringing in pretty much the first half hour.  In a rifle at the bench like the lighter lever guns, 10 min in and the butt stock will be trying to chew your shoulder apart instead.

So full loads are good for two's and few's to get ready for hunting season, but for a day at the range having fun shooting hundreds of rounds, go with a med load using something in the unique or universal instead. Both of these powders are bulkier powders, so even for med speed loads, you get a good case fill under bullet set.
