unique loads for the 480 Rug

[white eagle]

I have tried 13.0 gr and 10.0 gr on Unique in my Super Redhawk
The 13 I had to beat the empties out and the 10 gr load had stiff extraction as well
I am puzzled the loads are book loads

[Lefty SRH]

Thats odd, what boolit?

[Lefty SRH]

Are your chambers rough?

For a 400 gr cast boolit with GC, Quick Load lists the following;

480 Ruger Pmax pressure: 47,862 psi

400 gr GC boolit with a seat depth of 0.525 inches (QL SAAMI OAL)
10.0 grs Unique: 36,754 psi
13.0 grs Unique: 64,273 psi

400 gr GC boolit with a seat depth of 0.435 inches (my design)
10.0 grs Unique: 28,966 psi
13.0 grs Unique: 48,913 psi

Hopefully you were using a much lighter boolit. Here's a Lee 476, 325 gr GC;

Lee 325 gr GC with a seat depth of 0.447
10.0 grs Unique: 25,892 psi
13.0 grs Unique: 44,460 psi

Even the light weight Lee boolit is nearing max with 13 grains.

The SRH can certainly handle being a bit above SAAMI pressure, but I wouldn't be pushing it with a fast powder like Unique. Your best served with a slower powder like WW296 or H110 if you want to run them hard. Unique doesn't measure all that well to be pushing on it. 8.5 to 10.0 grains is a nice midrange load.

You also have to watch the brass used. New Hornady brass is about dead soft. It will stick even moderate loads when new. Once work hardened a bit by 3-4 firings, it comes around to what SL brass is new.

thanks Bruce and Lefty
I do not recall the boolit I was using
but I was in search of a easy to shoot light load
either I read the info wrong or I used the wrong boolit

[subsonic]

If you're "working up a load", you're doing it wrong

[Lefty SRH]

The charts say Trail Boss is a light load. You may want to consider that.

[Lefty SRH]

Titegroup also looks to be a light load also.

[subsonic]

I have seen some bad juju with titegroup. I would not recommend it in large capacity cases...

The Unique will work, just needs to drop it back a bit I think. Hard to say without knowing what boolit.

And this kids, is exactly why you work UP a load. Strange things happen.

Now, I am also guilty as charged of picking a book load and running with it. But I learned long ago to only load a VERY FEW of anything before trying them. Watched a buddy load about 350 38spls with the decapping pin in the progressive just bumping the primer enough to knock out the firing pin dent. Didn't catch it either.

Wow, thats sucks....a lot of time spent for dud rounds.

I have used 10 grains of Unique with 400 gr. Lee boolits.
One thing I noticed,when your looking at the load manual,look at the PRESSURES.
I havent had any troubles with Titegroup,its sold for large capacity cases,BUT the powder charge may be low but the pressures are a pretty good ways up there. There are no "light" loads other than Trailboss.

[subsonic]

I have heard lots of good things about HS6 in the big cases for easy shooting loads. I have played with it very little in my .475 using a load Mellonhead gave me of 14gr behind a 400gr Keith style he designed and a CCI300 spark plug. Obviously the .480 has less capacity and something like 10gr and work up to maybe 12gr sounds reasonable.

I plan on playing with Longshot someday and want to try some 800x, but 800x meters like cornflakes, so even if it is the holy grail, I probably will use something else.

[Lefty SRH]

I'd like to find a load with HS-6 and a 400-420gr boolit. I've seen HS-6 perform really well in my .44spl, .44mag snubby Alaskan, and my .45 colt. But 14.0gr in the .480 sounds pretty low considering I throw 13.0 in the .45 colt.
It would be great if Hodgdon would list some data for the .480 with some HS-6.

[mellonhead]

I use 14 grains of HS6 under a 400 grain SWC in my Linebaugh. I get right at 1150 fps. I have been using it in my 500 WE with excellent results also. 99% of my loading is done with HS6.

As in .475 Linebaugh?

BA Bore, can you run HS-6 and a 420gr LFN PB boolit thru your Quick-Loads for .480 Ruger and see what it says please.

[mellonhead]

Yeah, 475 Linebaugh.

My SRH had very rough chambers and made even the lightest load have "sticky" extraction. I polished the chambers with some scothbrite that I wound around an old bronze brush that I chucked in my electric screwdriver. After that even the loads that were well above max had the cases falling out of the cylinder by their own weight and the chambers were shiny clean even after a 100 rounds shot.

Shoot me the specs on the boolit. OAL and seating depth.

[Lefty SRH]

Shoot me the specs on the boolit. OAL and seating depth.

OAL length of the loaded cartridge is 1.750" OAL of the boolit is .950" Nose to crimp is .480" So the amount of boolit in the case is .470"
Thank you
