41 Mag. bullets

[kbbgood]

I am looking for a bigger Elmer Keith type bullet for my 41 mag. I think it is a 265 gr. bullet. I don't know where to find them though. Can anyone help me finding them and or the blocks to make them?

N.O.E. makes the Ranch Dog .41 cal moulds to 265 gr.

If you want to try a few before buying a mold Montana Bullet Works has them, Dave make good boolits and service has always been excellent.

The true Keith 41 Mag is a 220 gr. made by Hensley & Gibbs and is design #258. Accurate molds has it in their catalog 41-220K.

Is that the Ideal/Lyman 410459??

The nominal 41 caliber boolit(s) have mucho' penetration. Has to do with specific gravity of lead being perfect for the caliber. Therefore, 220 grainers exhibit more than enough umph for thin skinned game at nominal velocities. Tests were performed years ago using steel plates (old cars, et.al.) with all of the proverbial pistol rounds loaded at their nominal velocities. ... felix

The 410459 and the H & G 258 are awfully close. I have both, supplied some samples from the 258 for a group buy from Mihec for four cavity brass molds. That was a couple years ago but there may be some floating around yet. Both shoot well in my M57, my H & G ten cavity was just too heavy to cast with very much, and I didn't want to HP my Lyman four holer.

Might be the reason Keith/Jordan thought the .41 would be the perfect police round.
If I remember correctly, they thought the 41, ~ 220 at ~1100fps would be perfect. They had .357's and .44's to work with, still worked out the .41.....

[runfiverun]

they went a step further and went to the 41 special.
pretty easily giving that 1,000 fps velocity.
super heavy weight boolits in the 41 mag are not needed, the 220 area is plenty it provides enough sectional density and length to penetrate and enough velocity to shoot pretty flat out to 100 yds or so.

The first bullet on this page, 41-240K, was my design. It was intended for revolvers having a cylinder length that requires SAAMI spec overall cartridge length (e.g. FA M97). The bullet carries an abundance of lube (LBT Soft Blue in my case), and has four full-diameter driving bands. It works very well and is very accurate in my FA M97, Ruger SBH, and S&W M57 Mountain gun.

So where do I get the load data for these bullets?

Mr Keith preferred the H&G-- Saeco made a very close copy that shows up from time to time- I got a 4 cav last year weighs in at 230 gr

I got this mold cheap off of eBay, Having fun working with it!

11 Grains of H110 seems to be a bit hot.

You're using a 300 grain rifle bullet in a 41 magnum?

[runfiverun]

probably has a dan Wesson.
I shoot 250's in my 357 max but have to seat a tick deeper than the crimp groove.

I just sold a .411 275 NEI mold. It was a SSK design, a heavy boolit for the .41 magnum. I had shot a few, but they were more than I wanted for/in my Smith & Wesson 57. I did shoot a few turkey's and rams at the gun club range (60 yards) with them. These boolits dropped at 300 grains with my alloy. They did hit the steel with plenty of authority. I was loading them over 16 grains (max load) of H110.
To replace that mold, I bought (from one of our members) the Ranch Dog 411-255 RF. I just received it yesterday and cast up a bunch yesterday afternoon. I am waiting for my gas checks from Blammer. They should be here probably Monday. These boolits drop at 260.5 average. They should be about 265 grains with the checks. These should be easier on me and my model 57 as well.
For years, I have cast and shot the Lyman 410459 swc. I shoot it at about 1000 fps for my plinking loads, and for my wood packing load, I stoke it with either Alliant 2400 or H110. Around the mid 1970's, I took two deer with this boolit, and 8 grains of Unique. The first was a doe about 50 yards. The boolit hit just behind the front shoulder, and out the off side. The deer took few steps, and feel over dead. The second was a small spike buck running about 50 yards. The boolit hit high in the spine, and dropped him like a sack of spuds. I just goes to show, that one does not need full house loads to do the job.
There are many good boolit designs and weights for the .41. All the best in your search. I would definitely recommend the Lyman 410459 swc.

While the 410459 is an accurate bullet, it's not a "Keith".
The industry responded with the .41 Magnum in 1964, with S&W producing the guns on their N-frame, and Remington manufacturing the ammunition. Lyman immediately jumped onto the .41 bandwagon , advertising their new “.41 Keith SWC”, the Lyman 410459. There was only one problem -- Elmer Keith didn’t design the Lyman bullet, he didn’t particularly care for the design, and he didn‘t like his name being used to sell something that he had played no part in developing. Lyman had made the 410459 more aerodynamically streamlined by elongating the nose and making the meplat smaller, and they used a radiused grease groove to insure that bullets would drop from the moulds easily. Keith didn’t like these features; he liked a large meplat to create open wound channels and a “square-cut” grease groove to hold more bullet lube. While he grudgingly admitted that the 410459 was an accurate bullet design, it was just not right (in his eyes), and it certainly was not a Keith. He turned to Hensley & Gibbs to capture the concept of the .41 Keith SWC in metal -- 3 equal width driving bands, a broad meplat, a radiused ogive, beveled crimp groove, and a square-cut lube groove. The result was the 220 grain H&G # 258. SAECO soon followed suit with a similar design. In Keith’s eyes, the .41 Magnum was now properly endowed.

I've got a MP 41- 258 from Miha, he had some extra from a group buy from awhile back I believe. It's a true copy of the H & G 258 and casts/shoots beautifully!!!

Another plus in the DW cylinders is that you can long seat some boolits out to a grease groove. A tenth of an inch more of 296 can really make a diffrence.
265 grainers plus in caliber .41 is the reason I put together a Dan Wesson 414 Supermag. That extra case length gives alot of room for more 1680, 296 or whatever powder. Plus the long DW cylinders make for long seating boolits.
Liked it so much had JES rebore a Glenfield to .412 groove then chambered it to caliber 414 Supermag. That 20 inch barrel will give you approximatly another 350 fps over the DW 8 inch barrel.
Sooner or later a caliber .41 throater will come up and I will rethroat my caliber .414 SM TC barrel to take long seated heavy boolits.
