Please post a report. Do you have any HS6 to compare?

Thanks for this gold mine of information! I picked up my new Super Blackhawk January 2nd, I am now waiting on brass, bullet, dies, and a Lee 400gr mold. I have Unique, HS6, 2400, H110/296, and 300-MP on hand to try, I was very interested in the HS6 loads as it does very well in my FA 454. I am trying to decide between the Miha mold, an LBT, or a mold from Tom at Accurate Molds, I have molds from all of them and they are all top notch, with the LBT being the easiest to cast with. Thank you again!

So far I have tried HS6 and 4227 in my 480. 13.5 grains for the HS6 and it shot well. Did get some good results from the 4227 also. Loaded 21 grains. Used Fed. 150 primers for the loads. Did not set up my chrono as I was just testing for accuracy. I was using the MP 477-640 and the NOE 480-370 RF. Both drop at 388 with the alloy I used which was 70/30 + 2%. I did recover an MP slug out of the berm and it expanded perfectly. I believe this alloy backed by the 13.5 grains of HS6 is about perfect. I'm thinking the 21 grain load may be pushing a little fast for this alloy. My question would be if dropping to 19 grains of 4227 would be a better choice? This bullet weight is between the data shown for the 370 grain cast and 400 grain jacketed bullet loads. I also noticed after getting a front sight blade from sixshot that my Bisley has a tall blade. In fact it looks to be the same as the one I received from Dick. I'm still going to install it as I like it better. I'm shooting a little high but I still have adjustment on the rear sight.

Tank have you done any before and after hardness testing?

I'm at the point of loading for my Alaskan... curious why you are useing AA#5, HOOVER, unless it's what you have... the powder seems fast for the bullet weights chosen???
I've looked through 3 different manuals that have 480 in them ( the new Lyman manual most relivant since I'll be shooting lead ) I'm using a Hunters Supply 412 grain flat point, & plan on starting with AA#9 & Lil Gun... but my revolver is the Ruger Alaskan, so I may try the AA#5 listed, because of the shorter barrel... though I'd probably try AA#7 before the #5 with the weight of my bullets...
BTW... I'm looking for midrange pressures so they are shootable... but hope to find something accurate as well...
won't likely test velocities till spring... -17* outside right now

mag, according to the Hodgdon burn rate chart, HS6 and AA#5 are right next to each other, #41 and 42. I have an 8 ib jug of AA#5 and have never seen HS6 in any local stores. COR dropped off a pound jug of HS6 to me to try. I think it is THE powder for mid range loads. the 14.5 gr load crowds 1,200 fps with most slugs, with great accuracy. AA#5 also performed well. Cases just dropped out of cylinder with both powders.
I have since obtained a couple of lbs of HS6 for the .480 and plan on keeping plenty on hand.

Thanks for the reply... I have a good supply of #5, #7, & #9...
I've not loaded with HS-6 yet, but it's about the most available of pistol powders around here right now, so it might be a good option for my "snubbie" revolver...
was curious about the powders, as most manuals seem to graduate to slower powders as the bullet weights go up... I don't think Lyman has any loads using #5 for anything over 380-400 grains...
I have more #7 than any of the other listed powders... it's my go to powder for 10mm... so I might give that one a try...
really appreciate you guys posting your loads... I'll do the same once I get the Chrony out

Hoover, thanks very much for this thread and your data, which has been very helpful in getting me started with 480. The 14.5 grains of HS6 using the Lee 476-325 has been the most accurate for me so far. I'm also making test loads using the Miha in HP and Solid as well as the RCBS 476-400 with AA#9, 2400, H110, Unique and HS6. It's a long process but a lot of fun. Thanks again.
Chris

I saw something very odd with my Bisley .480 yesterday. I loaded up some NOE 480-375 WFN over 12.0-14.5gr of HS-6 graduating by .5gr each time. At 12.5gr the group looked like buckshot pattern. I mean I have never seen a group this bad! With 13.0gr it closed right up. At 14.0&14.5gr it got real tight, velocity was 1090-1100 if i remember correctly. I loaded some more Trail Boss using 5.7gr and they ran 620-630fps and sounded like a cap gun. The Trail Boss loads also shot about 6" higher than the HS-6 loads, i dont quite understand that part either. My other .480, a 9 1/2" SRH shoots both TB loads and the heavy H110 loads to the same POA. The Bisley is very different.

Slower load will shoot higher due to arch/rotation of gun and dwell tie in the barrel before exiting etc.
14.5 is a magic load in the 475L and I like the 14 in the 480. It's all I've shot for about 10 years or so in those. I really don't fool with the 110/296 loads at all. I haven't found that I needed them for the Critters I've shot with that gun.

Anyone tried 800x in 475L /480 R ?

I understand the dwell time and arch of the gun but doesnt really explain why my longer SRH shoots the same with TB or H110.

I got the chance to shoot my 480 Alaskan a couple weeks back, with 15 or 16 grains of #9 ( sorry I don't rember off the top of my head ) & the 412 grain cast bullet... sighting in was easy, ( I had just replaced the factory sights with fiber optic front & rear sights ) & after 2 cylinders full, I was ringing my 16 X 16 CAS AR-500 targets with ease from about 60 ft... temps were right around freezing, & I was using regular CCI large pistol primers... ignition was good... did notice a couple little ashy granules, but that was out of a 2.5" barrel, & really there was very little of it... for the most part, it was very clean shooting...
I think I want to try #7 next, along with those Missouri Bullets 340 grain powdercoated bullets... but there was nothing wrong with those 412 grain cast & conventional lubed bullets

I finally got back to the range today with a replacement chronograph and a fresh, new battery.
480 Ruger fired in 7-1/2" SRH
Federal 150 large pistol primers used throughout...
1. 385 Mihec hp, power coat bullet from Dick/Sixshot over 15.0 grains Hercules Blue Dot, 1162 fps avg., ES = 33 fps. 1153 FPE. Shows promise, need to get back and shoot some groups.
2A. 370 RNFP, hi-tek coating, over 8.0 grains W231. 854 fps avg, ES=20 fps. Nice, easy shooting load. 599 FPE
2B. 370 RNFP/ 9.0 grains W231, 929 fps avg, ES=14 fps, 708 FPE. Still easy shooting, even with my arthritis. Cleaner burning than 2A, cases fall from cylinder.
2C. 370 RNFP/10.0 grains W231, 1023 fps avg, ES=40 fps, 860 FPE. Primers still look ok, but a couple cases were sticky on extraction. Not sure if that was because of dirty chambers or high pressure, but I'll stick with 9 grains W231.
3. 370 RNFP/16.0 H108. 869 fps avg, ES=46 fps, 620 FPE. A definite soft shooter. I'm thinking a magnum primer and another grain or 2 of powder to work up...
