info on reloading for 41 Magnum


July 3, 2010, 06:20 PM
My landlord said he has a Ruger in 41 mag he rarely shoots due to ammo cost. When he saw my casting setup and reloading bench his eyes lit up, and he mentioned he thought he might have dies somewhere in his house, and possibly some brass. Now my question is....
What size primers? All I have are small pistol, that would be large pistol, magnum, right? Handgun powders I have are Accurate Arms #2 and # 7, saw some data for #7 on the Accurate website.
Anyone have a mould for a 41 mag boolit they don't need anymore? BTW, I am not selling these reloads to him, nor is this in consideration for reductions in rent or any other renumeration, that would illegal, just helping him out, he is a heck of a nice guy. Yes, I am dead serious.

Lee makes two molds for 41 mag, just a few $$. A 195 grain SWC and a 210 SWC.

Here's some on-line data.

The second site has AA#2 and #7 info.

FWIW, I think Unique will give about as great of velocity spread as you can find in any one powder. I used Unique and Universal the most with my .41, but I dabbled in AA#9 and 2400 before I sold it.

The Modern Reloading (second Edition) by Richard Lee has loads for .41 Magnum using AA2 and AA7.

that would be large pistol, magnum, right? Wrong.
Standard LG Pistol primers are all you need for AA#2 & AA#7.

Magnum primers are not used because it says Magnum on the cartridge headstamp.

They are used to ignite slow burning sperical pistol powders normally used in magnum calibers.

Not needed for faster burning, easier to light powders like you have.

OK, I didn't know, right now I load/cast in handgun just for 38 Special and 9mm. :)

I like running 6.3grns Titegroup, standard large pistol primer and Sierra 170grn JHP. I shoot them out of a Ruger Old Model .41. They are pleasent to shoot and they don't try to break your wrist,,,,lol.

#7 should be a great powder for .41 magnum. It performs just like Blue Dot but with less drama. All you need is standard LP primers, but using magnum primers won't hurt anything; just give you a different endpoint when you work up the loads.

Another often-overlooked powder for cast bullet loads is Herco.

AA #2 will be fine for light loads in .41 Mag, and AA #7 will be just fine for medium loads. As posted, Mag primers are not needed for those powders.

You will have to come up with AA #2 data by the seat of your pants, but you have a high pressure caliber so it will help protect you. The load would get very snappy and "un-light" like before you get into pressure trouble. Study AA #2 data for other calibers and compare any fast powder load data you can find. PM if you would like a place to start.

My favorite light .45 Colt load uses AA #2. (powder puff load I can shot all day)

The online Accurate PDF has some #7 data.

The usual mag powders will work if you decide to load some full loads.

For the .41 Magnum, #2400 is a great powder as is #5. #5 meters well and is great for medium plinkers. #2400 is good for higher velocity loads without much blast. For full power loads, skip H110/W296 and use LilGun.

Mild target load,

8.0-8.3 grains of Unique behind a 215 gr LSWC with a standard large pistol primer.

Gives about 900 FPS and is capable of very good accuracy.

Lee makes 2 different Dies steel wich requires lubing each case with a lube like rcbs lee etc. and can be messy as too much lube can dent the case etc but for a few bucks more they sell carbide dies wich I have 2 sets and the rest are RCBS and REDDING but wichever you get save yourself more work and get the Lee Carbide. You won't regret it. I load 357 sig, 40 s&w, 10mm, 41 mag. 44 mag, 460 & 500 alsoas well as the std calibers and only the 357 SIG I had to buy steel as its a shouldered case and carbide isn't made for them Dang. they are another step I could do without and I agree on lil'gun for full power loads I've just started using it and it is hotter than H-110 but with much less pressure but my old favorite is 17.5 of 2400 behind a 210 grn Hornady xtp
