So I have 2 - 480's... an Alaskan, & a custom 5" barrel Super Blackhawk... what can one expect with heavy bullets out of both of these barrel lengths... so far I've only checked the velocity of a medium starting load with a heavy bullet out of my 5" Super Blackhawk & was only getting 740ish fps... I was pretty stunned it was that low, made me wonder what velocity those would pull out of the short barreled Alaskan... These loads were with a 375ish grain cast bullet... what would you expect the minimum killing velocity ought to be ( killed a possum dead right there, with the Alaskan, with these loads ) but obviously looking for the same results on dangerous game... Alaskan is to be used as designed, IMO, the perfect "bear get off me gun" thinking 900 -1100 fps would be close to my target, for both barrel lengths... thoughts & actually I now have many boxes of these Lehigh Defense 330 grain WFN solid copper bullets ( I accidentally double ordered... thinking I have 400 of them ) www.midwayusa.com/product/337435/lehigh-defense-match-solid-bullets-475-caliber-475-diameter-330-grain-solid-copper-wide-flat-nose-lead-free-box-of-50these should be a good platform to launch... thoughts on effective velocities with these 2 bullets... out of the snubbie & the single action on larger or dangerous game... |

You should be able to get 1200 fps with those 375s from the 5" 5 shot. At least 1k with the snubbie. I worked up a load with the Accurate Molds 380V boolit. I was beating 1200. Closer to 1300 fps from my 7 1/2" 6 shot SRH. With Accurate #9 powder.
The Accurate Powders reloading manual has some good data in it. You can download it for free.
Those solids should go over 1400 out of the 5" and at least 1100 fps from the Alaskan.
At least that is what I would expect with magnum powders .

First choose the bullet that you like the best & that you think will work best for you & then load it up as far as you are comfortable shooting that bullet. After you've done that, check your chronograph & see if you are happy. Don't worry about velocity if you can't handle the recoil. That's what I would do if I needed a "shoot it off me" load. Those big bullets will take pretty good care of you if you place them correctly, speed is good, placement is more good!

Am just up and on here. In a bit I'll go to the basement and see what velos I got from first shots thru the new chrono and see if any of those numbers will help you. The Lehigh WFN was tried. A certain experienced tipper of bovines told me/us that with the solid copper offerings, good things happen at 1300 fps and beyond. I'm still a grain or so below the powder charge quoted me. My velos from a 4 5/8" BSBH. The heaviest bullet here is a batch of Sixshot's 385gr HP's. The few loaded ones here, now, on Longshot and I'll bring that data up and post. If I dont have it , will go out and shoot a few this am..

I did find some loads on the www yesterday... comparing the Alaskan to 7.5" barrel in 480 Ruger ( both were Super Redhawks ) & in my case it would be one double action, & one single action... most were running between 225 & 275 fps slower in the snubbie... so I'm guessing 175 - 200 fps between my 5" & the Alaskan, load for load...
thinking some faster powder experiments might be warranted for the Alaskan... for example AA #9 is a little faster than Lil Gun, H-110, 296 & 4227... I found data for Long Shot, & it's a bit faster than AA#9... but AA#7 is only 2 powders ahead of Long Shot... thinking these faster powders may perform better with the snubbie & the lighter copper bullet...
I do have 2 Accurate manuals, but both are old enough that they don't have 480 Ruger in them... so I just copied that page off line... I see they do list loads for #7 & while they are close or slightly lower velocities than the other powders listed... thinking the faster powder won't give up as much to the shorter barrel of the Alaskan...
looking like this spring I'll be playing with the 500 JRH, & the 2 - 480's to start with...

Ok, so the 385gr HP was my surprisingly slow/light load. 11grs of Longshot averaged 925 fps.. Not useful to you. The Lehighs on 13grs of Power Pistol averaged 1190 fps. Another grain to go to the charge weight I was quoted to give 1300 fps in a longer barrel.

I've not used Power Pistol before... it's a faster powder than most load recipes I'm finding... it falls between AA #5 & AA#7, & is slightly faster than Long Shot... to my understanding... the faster powders are not recommended under heavier for caliber bullets as they can raise the chamber pressures quickly, but ( again, my understanding ) as long as they are not too fast or loaded too hot, they can reduce the "flame thrower" effect of too slow a powder burning outside of the barrel... finding a good match for bullet weight, verses barrel length, & pressures would get us the most efficient ( & in theory ) consistent loads... one powder is not going to take us from the lowest, to the highest practical velocity, or the shortest, to the longest barrel with the best consistency...
I'm quite sure I'll end up with a best Alaskan load, & a best Super Blackhawk load... may be able to use the same bullet, but will likely be using at least slightly different powders

Thanks Max, was, am, being cautious. Did not recall if the "14gr-14.5gr" was read here or came to me in a PM. So have left off mentioning that 14.5gr part. Am currently outta Lehighs to go higher, hotter, and it's trout season then crazed yard work mode and won't be moving forward on these loads for a while.

Mwm ;
Have you done any workups with these bullets and powders yet in your 480s?

been wanting to... but life has been too crazy lately, for me to find some quiet time in the gun room... I've got load data, bullets & brass sitting there for 3 calibers to load right now...

Believe me, I know how that is.
I managed to get a half hour a couple days ago to load about 20 rounds of 416 that I had all prepped and in the loading block.
I need to take a day and load up a bunch of 480 as I'll be moving in June and all my reloading room will be packed away for prolly 6 months.

MRS does quilting weekends, and those have been my best time to reload... but I’ve not been able too the last couple times... so I’m way behind on loading

Have you thought of good old UNIQUE.... Just looked over on LoadData.com and they have quite a few loads from 900 to 1400 fps with bullets ranging from 285 to 405 grains...
I used it in my .475 Linebaugh for light loads...

I've actually loaded quite a bit using Unique... in other calibers... it's pretty smokey unless it's loaded under heavy bullets & with a heavy crimp... I don't personally like how it meters, being a flake powder, but I seem to still get pretty consistent velocities from it even if the powder charges vary a few flakes from load to load... might have to try it in the 480  |
