Loading cast bullets for 44 magnum

[Mfy3624]

First time posting ,
Picked up 500 rounds of SNS casting 240 gr LSWC
trying to come up with a good target load ?
I will be loading for my 629 classic 44 mag
And using w231 because I have quite a bit of it and cci300 primers.
I tried 10 grains of W231 per Hodgdon website trying to get around 1200 fps. Shot twelve rounds and appears to be some lead build up. A little fast for lead ? I’ve been loading for years but this is my first attempt at cast bullets .

I use unique powder for all my leadcast bullets. I get very little to no leading. At the end of the shoot I do run some jacketed just a few rounds.

 

[arjay]

Try them at 900-1000 fps

Your cast bullets may not fit your gun well and 231 is not the best powder for 1200 fps velocity; it's a bit fast burning for that speed. However stick with it anyway and try backing your load down a half grain or a grain at a time to around 8 grs. to see if leading will stop and check the accuracy as well. Shoot at least one 6- or 10- shot group at 25 yards benchrested with each load change. If you really "need" 1200 fps, I'd try a slower powder like #2400, if you can find it.

I’ve had a similar experience with W231 trying to push cast bullets hard out of a 357. I’ve found unique and 2400 to be my favorite powders for cast midrange and magnum loads

Try 7 grains for a more pleasant load.

Try seeing how your bullets fit the chamber throats on your revolver. They should go thru with a little resistance. If they just drop thru, they are a little undersized, and combined with a hot load and a bevel bullet base, can lead to leading. Also pay attention to where the leading is occurring. If its mostly in the first half of the barrel, its usually poor bullet fit, if mostly the end of the barrel, its usually a lube failure.

Agree with the above posters - 231 is not an ideal powder for magnum strength loads in the .44. Too fast and peaky for the application. Personally, I like Red Dot with a 240 cast SWC, at about 900 - 950 fps. It works well in most of my guns. I use W231 also for similar loads, and it works well at those velocities.

A trick I tried several times with commercial cast bullets that were leading a couple of my guns was to roll some blackpowder "Wonder Lube" on them before seating. Kind of a pain, but it did reduce leading in those guns quite a bit, at least at the sub max velocities I usually use. Gas checked bullets can also make up for less than perfect bullet fit or a less than smooth bore, but both are band aid approaches to the real issue of good bullet fit.

I’ve ran those SNS to 1200 fps, but I used 2400 to get there. Those coated bullets are hard and can be pushed fast.

MFY3624 - How was the accuracy of your loads at that estimated velocity?
I don't load .44 mag for handguns, but do load cast 220 gr. Keith SWC's in .41 mag for my Rugers and S&W's. 6.8 grs. of W231 and CCI #300 primers will group ~2.0" at 25 yds. in my revolvers - with NO Leading. Chronographed velocity is +/-1,000 fps.
I've pushed the same bullets to over 1,200 fps. (actual chronographed velocities) with no leading, but I was using 2400 powder.
I would check the diameter of your bullets - they should be at least .429", .430" would be better. Undersized alloy bullets pushed too fast will leave a lot of lead behind.
I would suggest dropping the velocity of your loads down to the 900 fps range and see how they do. Don't give up on shooting cast bullets, they're less expensive than jacketed and will handle at least 97% of your handgun requirements. The learning curve is just a bit longer.

This is not the load the original poster is looking for, but I don't load .44 magnum anymore. I use a 231 load (6 grs.) in .44 Special with a 200 grain flat nose (SAECO mould) cast from wheelweight alloy and sized to .432". Muzzle velocity from a 4" barrel is, I think, around 830 -850 fps, from my 29 and 24-3s.

Accurate and pleasant to shoot. I loaded .44 Magnum for more than forty years and now I'm not sure why I did that.

 

[Mfy3624]

Thanks for the info .
They were very accurate , I’m using a red dot and the group was under six inches at fifty yards . The bullets measure .429 to .430 you can not push them through the cylinder . I’m getting exactly .429 on all six of the exit bores .

 

[minconrevo]

Try your cast lead bullets at about 900 fps using Unique or perhaps Red Dot. BTW in .41 mag target loads with cast bullets Red Dot is the berries!

 

[alwslate]

Everyone has opinions based on their experiences and here are mine. Forget crappy Unique. You can’t find a better powder for your loads than your 231. 1200 FPS is too fast for target loads. Use 8 to 8.5 grs of 231 for around 900 to 1,000 FPS depending on your barrel length. Make sure you use a good roll crimp in the crimping groove of your cast bullets.

8 grains of W231 and a 250 grain cast bullet has been my favorite general purpose load for the .44 mag for over 30 years.

 

[Ruger 13]

10 grains of Unique and Elmer’s bullet is very accurate in all of my revolvers.

I like to keep lead at 1000 fps or less, except for my really hard cast, gas checked hunting loads.

Try 8 to 8.5 gr. of Unique.

If you're insistent on 231 just drop down to the 1000 fps mark. To me, 231 is kind of fast for anything other than lower velocity target loads in the 44 mag.

This.

About 10 grains of AA#5 will do the trick. This load is not listed in the AA reloading guide. I extrapolated it from .45 Colt data in the AA guide.* Accurate, punchy but not painful, easy on shooter and gun, and should kill any game in North America, if used for hunting.

Asking about cast bullet loading on a forum will produce a lot of "Old Wives' Tales" and plain old misinformation.

I have reloaded cast bullets in my S&W 629, Ruger SBH, Dan Wesson 44H, Contender and Puma carbine starting in '88. I have reloaded everything from cast 123 gr. balls to 300 gr. ingots. Normally I prefer Unique, Universal, 2400 , but I have used, quite successfully, W231 (9.9-11.0) and Bullseye (8.9-9.8 gr) in magnum loads to close to 1,200 fps.

The single most important factor in loading/shooting lead bullets is bullet fit (I didn't see the bullet diameter on the SNS website, measure yours and for starters .431" is a fair starting point). Bullets must be larger than groove diameter to seal the bore and prevent leading, so I size (or purchase) my bullets to the same diameter as the cylinder throats. I have driven my cast (429421 plain base, BHN 12) to well over 1,200 fps many times with no/minimal barrel leading (fit is very important!).

This will get you started, but I recommend getting a copy of Lyman's Cast Bullet Handbook (3rd Edition is a bit better than the 4th, if you can find one) and hanging around the Cast Boolit forum Cast Boolits

Elmer Keith who was the father of the 44 magnum believed in a bullet alloy of 1 part tin to 16 parts lead which gives a Briin
ell Hardness Number (BHN) of about 10. This is very soft by today's standards but Elmer apparently had no particular problems driving cast bullets over 1200 fps. Today's commercial cast bullets are usually composed of an alloy of 6% Antimony, 2% Tin and 92% Lead for a BHN of 18 which is quite hard. There is a school of thought that believes incorrect bullet obturation is a major cause of barrel leading and that a BHN of 12 is a good temper for general purpose shooting, 14 BHN for magnum handgun, and 18 BHN for rifle loads. Under this theory, your leading problem may simply be caused by an incorrect bullet hardness for your application and a softer, more plastic bullet may cure your problem. Food for thought....

 

[THE PILGRIM]

It’s been a while since cast bullets, but I used Wheel Weights to get Antimony and I added Pure Tin.
I had a bunch of pure lead and added some of that.
Loaded 44s and 357s at about 1200.
Recall more leading in my 357s than my 44s.
