Anyone care to suggest a starting load for either of these bullets.
I have 2400, H110, H4227, and Unique. I want to try Unique with the 300 grain bullet, and was thinking 7.5 grains to start.

300SSKPB
and
280LBTLWNGC

Will look for published data as the bullets i worked with were not quite the same as anything out there and my results won't match.

OF the powders listed, PLEASE start your work with H4227. It may not be the best powder, but it will be the hardest to get into trouble with...considering the volume of the case left after seating tose heavy bullets, it will be hard to get a serious over load into a case. Once you get a handle on H4227, then can work with the others.

Unique is a bit faster than the others listed, and heavy bullets with faster powders tend to run pressure up quickly.

---------
Long time ago, when the .41mag. was a baby, they didn't quite know how it was going to be used. Lyman made some 210gr. HBWC molds. By making new hollow base plugs (some not hollow based) and seating backwards, made various weights from 210gr. to 340gr. with RN, SWC, or FN shapes.

Now these probably set a bit deeper than anything offered commercially in that weight, so my case volume was a bit liss...but IMR4227 was the accuracy choice. normally 4227 doesn't burn real well in revolver rounds, leaving a good bit of unburned powder littering the barrel...but with a heavy bullet, that powders seems to burn quite well. Won't be as fast as can be had with some of the other powders, but it's a good place to start looking for accuracy with near 100% loadfing density an safe pressures.

Brandon,

There are some proven loads at www.LoadSwap.com with the 280gWLNGC bullets using both W296 and H4227. Here's the link:
http://www.loadswap.com/display.php?...cartridge_id=3

And for the 300g SSK bullet try this one also from LoadSwap.com

http://www.loadswap.com/display.php?...cartridge_id=3

This should get you started!

God Bless,

Thanks, seems the starting points I had in mind were just right. Unless its cloudy or windy next weekend I will be able to chrono my loads (about 13) for my 41 and add to loadswap.

We'll look forward to your results, and the new loadswap data you develop!

God bless,

Well I sure did have some good shooting. I will get all the data on loadswap when I review my notes and enter them into my data base, but H4227 did pretty good with the 280's. Out of 7.5 8.0 and 8.5 the 8.0 was the best with Unique. 8.5 was opening the group back up. However 8.0 placed 10 shots way under 2 inches at 25 yards. The recoil was very mild and the sound was more like a thump than a crack. It was a pleasant experience and I had very little trouble with unique trying to cook the base of those bullets. 7.5 was 950 fps, 8.0 was 1000 fps, and with a large SD 8.5 was roughly 1050, but I could tell i was past the prime pressure.

I started with 18.6 and worked through 19.4 gr. of H4227 with the 280, and they all performed OK. I noticed that the SD were low in some loads, but the accuracy wasn't exceptional. I am still fairly low in velovity at around 1200 so I am deffinately going to go further with this. For now I will say the 18.6 is a very good mark to start with, and was very pleasant to shoot.

Load Swap data is up. Chronograph is a brand new Oehler. I added a few more loads that I feel like might have some use.

Brandon,
Many thanks for taking the time to post your work on LoadSwap.com! It's a great addition for those shooting the .41 Magnum. I appreciate your efforts!

God bless,

Going at it again with the 255 and 280.
The 255 is suposed to be the best performing most accurate bullet for the 41 mag. ( I have heard from a few sources) Frankly against the 280 from Marshal, I am not so much impressed. I am putting these two head to head. I allready have a good load for deer with the 280, so now I am just playing.

Now i don't wanna step on anyones toes, but I see 21.0 grains of w296 getting 1350 fps or so. Now I am going to asume this was a cool burning lot. Lots of people say 296 adn H110 are interchangable, however in this case I am going to drop on back. I think 17.6 or so will be a good starting point for all using the 280 with H110.....................Ima start there adn work up pretty strong.

Will hopefully get this stuff through the skyscreens Sat.
