I am a little confused here. In several posts I see reference to "boaring" a .480 out to .475, or "opening" one up. I may be mistaken, but I'm pretty sure that the bullet diameter is the same and that the .480 is mearly a shortened .475.

You're in the wrong place. Frequent the forum at Sixgunner.com if you want .500 Linebaugh discussions.

Jeremy, you're right. The .480 Ruger is just a "lite" .475 Linebaugh; just a little bit shorter. I think they mean lengthing the chamber, but I'm not sure...guys?
I agree with yukon delta,the operating psi"s of the two cartridges are NOT the same. Go to Hodgons website and compare the two! THe Linebaugh pressures are higher than the 480,makes sense since the case is bigger,holds more powder!?? To each his own, if you are comfortable pushing the "edge" then go for it!

FWIW, the 475 Linebaugh was designed to operate at a maximum pressure of 50,000 psi. That's according to John Linebaugh's information at sixgunner.com. Yes, the Hodgdon data is hotter than that, and some shooters load even hotter than that. (Hodgdon's 500 data is much hotter than John ever intended. According to him, "the 500 is a mid 30,000 psi gun.")
I don't know what SAAMI max is for the 480, or if it's even been standardized, but Hodgdon lists loads up to 47 or 48,000 psi. So from a design point of view, they're pretty close. I'm confident the SRH would take a lifetime of 50,000 psi loads.
If you want 475 Linebaugh performance from a 480, there's really no reason to lengthen the chambers. The same thing can be accomplished by seating the bullets to the same OAL. As has already been pointed out, however, recoil simply isn't any fun once you approach full-power 475 loads.

When you say the 480 is designed to operate at the same pressures as the 475...that's like saying the 45 colt can operate at the same pressures as the 454. T'aint so. There's about 10k difference in psi (for the 475's) which is a fair bit of difference. What Ruger did in designing the 480 was to make a "Linebaugh special" which might appeal to a bigger market. The problem is that everyone wants to make the 480 scream. By the time you get good pressure and things start to cook in the 480 you have reached 475 recoil in a smaller case. No flies on the 480 but it's not a 475. Hodgdon's data shows a 385 gr. in the .475 can take 30 gr. H110...the .480 can take 26 gr. H110 under a 370 gr. slug. Thirty grains of H110 is a whole bunch of juice.
My point is that you have to really lean on a .480 to make it look like an average 475.

If you want a .475 performance, GET A .475!! The .480 Ruger is a round that does not need to exist. 325gr @ 1350fps (rated out of a 9" barrel )...hmm, sounds like the .50 AE. At the .50 will do it out of a 6" barrel, with a heck of a lot less recoil. At least in the DEP. Never tried it in a revolver. Although the .50AE Super Redhawk conversion Bowen does looks interesting...
correct when a bullet deforms or verse from its stiaght path in any way penentration suffers.

when you say a slower bullet will penetrate better, is that because at the higher velocities they are fragmenting too much? I don't quite follow. Just curious.

The chambers on the SRH are too short to seat the bullets out another .100" to the 475LB length, they must be lengthened... You can, after this use either 480 or 475LB brass to seat bullets to the 475LB length, cannelures however will not cooperate and must be crimped without one.
At 40-55k psi the 480 and 500 will weaken and or fail and are WAY unsafe to use beyond 30k psi, the 454 and 475 are the only ones designed to... That's BULLSHIT and we all know it. Cases are the same design and will take equal pressure. And loaded at equal psi the 475 is superior BECAUSE of the extra capacity only.
I have loaded 45's in my 454 TO 454 psi also... what gives? Don't recomend you do this in your OLD 45 though.
Do you need to stand on your loads? NO, lets all go back to our 45LC's and be satisfied...
dont agree with this statement. The .480 is a wonderful cartridge. Most of my .475 loads are .480 level loads. It has alot more punch then a .44 or .45 it has less recoil then a .454 or .475 and it allows people who cant afford to buy a linebaugh to experience a true big bore. The .50 ae is another good one though I have never owned one. Problem is again if you want it in a revolver you have to pay the piper. If ruger would see to chamber it in a bisley we would have the best over the counter reasonably priced handgun out there.

Glock20rocks I have to agree with Lloyd. The 480 is a step up from the 44 especially if you handload. The key is it bullet weight. The 480 is a wonderful round. It is not a 475 but it is a powerhouse in its own right. If the 475 was never made and the 480 came out on a fresh piece of paper people would be the greatest thing that happened since the 454. It was designed to be put in a platform that already existed, good, bad, or indifferent. Some people can not afford a 475, lets face it, even used they still are not inexpensive. The 475s are a custom or semi custom guns. This same reasoning as the 480 is the same reasoning behind the rumer fo S$W new 500 S&W.
This is what make America great freedom to do what we want. A new 475, 500, 480, 44, bore a 480 to 475.

True, the .480 is a nice step up from the .44 Mag, but there are also "hot" .45 Colt loads and "mild" .454 rounds that are close or equal in performance (like PMC's 300gr .45 Colt). Yeah, the .50AE is NOT a revolver round, even though Freedom Arms and MRI make one. Still wouldn't get one, though. For .480 level power in a revolver I think the best is the downloaded .454/hot loaded .45LC. Just my $0.02...

I can only speak for my own gun, but I have no problems seating both WFN's and LFN's out an additional .100".

Look at the linebaugh seminar results from last summer, and see how the 480 performed with my 460 gr bullet at a leisurely 1100 fps from a 480.
Those that criticisize the 480 have never shot or loaded for one. No, it isn't a 475, was never meant to be, and doesn't need to be one. 400 gr @ 1200 fps is a formadble hunting load, and most importantly, very shootable. IMHO, recoil climbs at a much higher rate then actual killing power when going to heavier loads. If you need more power in the field, then its time for a large rifle.

I was at the seminar and saw all of the testing. I'll be the first to say that a large bullet at the proper velocity doesn't care what the name on the barrel says. Having said that, I didn't hear anyone say they regretted having spent more money to have the 475 built. Most guys prefer the single action and if you're going to have a custom cylinder built you should probably choose the 475 over the 480 due to greater potential.

I was at the seminar as well -- I'm trying to figure out if we met. I'm not touting the 480 SRH as the equivalent of a custom Ruger in 475, but the difference is in the guns, not the cartridge. The Bisley (for me at least) handles recoil much better, and will probably stand up to higher pressures. (However, the 480 SRH is fine to at least 48,000 psi, and John never intended for the 475 to be run hotter than 50,000.) The difference in case length is irrelevant if the cartridges are loded to the same OAL. Same is true of the 45/454.
