Hi everyone, I'm a new Marlin guide gun owner and wondering if anyone has had any experiance using 4227 powder. My bullet of choice is a 425 grain hard cast with gas check. I'm looking for some help with load data in achieving 1450 to 1600 feet per second with 4227. Also wondering who has the best reloading guide for cast bullets in the 405, 425 and 450 grains weight range? Anyone not wanting to post reloading information on this forum can e-mail me direct at; email@example.com
Thanks for your help and keep your powder dry!
Lymans Cast Bullet Handbook and 48th Reloading Handbook are good places to start looking for cast bullet data. Both are available and a good addition to any reloading library.
I have a Lymans reloading book , and there is no data for the 425 grain bullets. Thanks anyway. BTW, 4227 is a good powder for the 45/70. I'm just looking for a starting point and a stopping point for my loads.
I can't offer you any load data other than 4227, be it H or IMR, generates a lot of pressure. I wanted to work with H4227 in my 375 Win, another straight wall case, because my Load From A Disk software recommended it as a promising load. 34.0-grains producing 2028 FPS and 43.9 CUP (48.6 PSI). Luckily, I started with an 80% density of 26.6 and it put me on high alert not because of the velocity (1949 FPS) but by the fact that it generated 52.9 PSI! My nephew was shooting the strings, so what the heck, we went to the next interval of 28.0-grains (84%) density and it produced 2022 FPS and 63.2 PSI! We had five more strings working toward the recommend 34.0-grain load but ended it there!
I also don't think that the powder, and others that are similar, produce very good accuracy results. It lays horizontally in the case instead of up against web for uniform ignition. There is evidence that these type of powders become a shaped charge in the case.
I haven't finished formating the charts for my web site yet and won't have time until after the first of the year but in the bullet range you are interested in I've seen very good results with BL-C(2), H4895, and Varget. Low pressure, velocity in your range of interest or slightly higher, and excellent accuracy generated by that full case of powder.
Someone told me that 4227 would be a good powder for the 45/70. I was given a load of 30.0 grains 4227 and told that it should give me around 1400 feet per second. But not given an actual starting or stopping point and thats why I decided to ask here. It sound like this is a powder that should not be used in the 45/70 case. I have seen the powders you mentioned given many times for 45/70 loads, espcially the H4895. I've also been seeing that a lot of shooters are saying H322 is the best powder for the 45/70. I guess I need to be looking in the direction of Hodgdon's 4895 or 322 for my loads. I'm only looking for a load that will give me around 1450 fps and maybe up to 1600 fps max! I'm not looking to punish my shoulder, and I don't think the 45/70 needs to go any faster than that to accomplish its job on any NA game animals. THANKS RANCH DOG!!!
I checked over my 45-70 data, most of my loading manuals, Hodgdons Reloading Center and Load from a disk and couldn't find but two references to using 4227 powder. One was for a 300 gr Speer bullet and the other was for the Nosler 300 Gr PT. It isn't one of the powders I would use for this application being faster than 4198 which generates as much pressure and velocity as I want with a 400 gr bullet. Maybe for light bullets and light practice loads, I can't say not having used 4227 in this application.
Check out the Hodgdons Reloading Center,
for a list of loads for different powders and, of course, Beartooth Bullets,
My NEF BC is most accurate with H4198, H4895 or RL-7 with any jacketed bullet weight. I haven't tried the 425 or 525 Piledrivers yet as I like jacketed bullets over cast lead, but the 525-550 gr cast lead slugs are on my "to try" list. H322 and AA2015 are other good powders to try.
Glad I'm not Ranch dogs nephew. :shock: :roll:
Thanks NFG, I am now looking for a load using either H4895 or H322, whichever will give me the velocity I am looking for with the best accuracy at 100 yards.
I use 25 grains of 2400 under a 405 as a mild load in my Marlin.
Seems pretty acurate enough. I forget exactly the velocity but I want to say 1300fps or so.

I use the same load Leverdude. I want to say it chronos at around 1500fps, but, I could be wrong.
After absorbing everyones advice about powder and loads, I've decided to exchange my H4227 powder today for H322. Everyone seems to be saying the same thing about this powder, thats its the best choice for the 45/70, we'll see. I also picked up the new Lyman 48th load book which has a good half dozen different loadings, including 322. Loading in this book shows a starting load of 43.5 grains of 322 up to 48.5 grains for a 405 gr. bullet. The 425 gr. bullet is so close to a 405 gr., that this data will work fine since I'm not planning on maxing out my loads. Wishing you all a fine Christmas, and don't forget to keep your powder dry & seal your primers
