I have used all the before mentioned loads in my SRH 480 and had the same results but I wanted to do better then 2 inches at 25 so I went to a 400 grain cast with 20 grains of H1110. 1150 out the barrel with a KO of 32 and it's fun to shoot. When I tried the 300+ bullets they were not that fun to shoot, but to each his own
HI! I'm new to this forum, just migrated from the Marlin forum. I have a 480 SRH with 9 1/2 bbl. While I don't have a specific load for your bullet, I do have a couple good ones;
Speer 274 gr GDHP
WW 296 34.0 grs
CCI 350 Primer
Velocity: 1,690 fps (Speer data, same gun)
Accuracy: 1 1/2" 5-shot group @ 50 yds, 3 group avg.
CPB 410 gr WFNGC (Cast Performance Bullets)
WW 296 21.5 grs
CCI 350 Primer
Velocity: 1,250 fps (Chronograph)
Accuracy: 1 1/4" 5-shot group @ 50 yards, 3 group avg.
All testing was done with a Burris 2-7x scope set at 5x. WW 296 and H110 powders are the same, so I stuck with my large stash of 296. I did try Hodgon Lil' Gun. It was to erratic on pressure. I would ease up on max 0.5 grs at a time. The Lil'Gun powder would start to show a slightly flattened primer, then wam. A 0.5 gr increase and you had to pound the case out of the chamber. I have heard similar comments from magazines and forums. Yes, I did check my lot # for the Hodgon recall. All of my loads will flatten the primers slightly, yet still extract normally. I did find that all of the Cast Performance Bullets were very accurate. I have tried or witnessed their grouping ability in the 357 mag, 44 mag, 45 Colt, 454, 480, 450 marlin. Hope this helps.
Babore, Hello, and welcome to the boards.
Thanks for he timely information.
I am thinking about either a .454, or a .480 Ruger.
It is still a tossup as of which one to go with. I am sure it will be a factory rig, with a little tlc.
Then to try to figure out what bullet and loads are best.Just trying to figure out what would be best for a regular carry sidearm for the trails and fishing camp, up yonder in the northern lights.
Kcih, Thanks for the thought.
I have looked aty loadswap, comparing cartridges that way.
Around here there are not many shops with anything other than either 9mm, or the .45 auto, with a few small - med frame revolvers.
When you try looking into the big bores, everyone just looks at you kinda wild eyed.
Got into the 454/480 discussion on the Marlin Big Bore forum, things got quite opinionated. Bottom line, they're both good rounds. You'll get higher velocity with the 454 using the lighter (260-300 gr) bullets. When you get into the heavyweights, 454 360 gr, things start to equal out. This high velocity does come about with a much higher operating pressure, gun wear, etc. The 480 can handle much heavier bullet weights. From your post I gather that your looking for bear protection. That means frontal shots which means penetration and stopping power. Bigger is better. Take a look at John Linebaughs penetration test with different calibers. He
has a web site or you can link through several bullet & custom sixgun sites. He shows that a heavy, large caliber slug, at 1,200 to 1,400 fps will out penetrate even the same bullet at a higher velocity.
In regards to the comment on the Hodgon data, I to was dazzled by it. But it's not real world. A pressure barrel was used for testing, so your velocities are going to be lower. I used their data when first working up loads for my 480. I could get near their max charge with WW 296 but pressure was excessive. Cut my thumb up trying to push a single empty out of my SRH. Very very sticky extraction, yet the primer was not excessively flattened. Backed the loads down for easy extraction. I have heard of the same problems with the 454. Note; this does not seem to be the case with the Casull or custom guns (Tight chambers). Hope this helps.
Hey a side note from a newbie. How do you log out of the forum? The only place I've seen was at the reply screen.
