It does not take Rocks & Dynamite to stick brass in a chamber. All it takes is a wavy chamber wall, a bit of reverse taper, or unnecessary roughness. Recall S&W introducing many years ago ROLLER BURNISHING to finish chambers and ease extraction. Simultaneous extraction in a double action requires smoother chambers than the one-at-a-time extraction from a single action.
Some believe a degree of roughness in a chamber helps hold the case against setback. The .357 Maximum has straight, untapered chambers, reamed smooth but not roller burnished. Extraction is not a problem. Introduce aberration and all bets are off. The Dan Wesson Arms M40 simultaneously ejects fired .357 Maximum without a hitch.
Chamber finish is a big deal. David Bradshaw

I had one of the first 480s back in the 2001 time period or whenever it was. It did have extraction issues but a quick trip back to Ruger and it was perfect.

According to Whitworths posts when the 480 SRH was reintroduced, burnishing was what was utilized to cure the extraction issues.

I just picked up an early SRH target grey 454 and the first time shooting it I had hard extraction. Now I was shooting some pretty hot reloads, 300gr XTP Mag's. When I got home & cleaned it I noticed the chambers are pretty ruff with tooling marks. I wound up backing the loads down 1.5grs. (31grs.) & no more hard ejecting. Im wanting to polish up the chambers a little bit I just haven't gotten around to it yet. I see Brownells sells a couple different polishing hones for the job. A medium grit & a fine grit. My question is if I just get the medium grit hone will the finish be good enough to leave it as the final finish? Or if I just get the fine hone will it do a good enough job by itself. It doesn't give the grit #, just med. & fine.

I have the 480 5 shot Bisley, bought in December. The first 15 shots through it were hard to extract. They also didn't want to go back into the cylinder after being ejected. I looked at my brass (Starline) and could see about 1/8" above the rim, scratches that were about 1/8" long. I took a smooth round ceramic rod and hit the very rear of the cylinder holes. 15 seconds on each hole smoothed whatever burr there was and I was then able to insert the previously hard to insert brass easily. The next time I took it out the same brass and load dropped out of the cylinder by just tilting the guns muzzle up and rotating the cylinder. I think the chamber reamer left a burr that caused the problem.It is funny that whoever test fired the gun didn't fix/report the problem. I had never heard of this happening to anyone else and thought mine was an isolated fluke.

I wound up calling Brush Research Mfg and talking to a guy about what I wanted. He said all I needed was the finer grit brush (800). So I ordered one from them, $10 cheaper then Brownells.

BigBore44,
I got both in 480. The older Target Grey does have slightly harder extraction than the new model, but nothing a good smack on the ejector don't cure. I personally like the older model better. Mine has much tighter tolerances and lock up than the new model. The older model points better for me as well with it's lighter tapered barrel.

When I had my older 454 SRH I never experienced difficult extraction with handloads or factory loads. But then I wasn't pushing my handloads to the absolute limit either.
When I was shopping for a 480 SRH, I would have bought an older, target gray gun but people were asking NIB prices for their used guns. Then CDNN ran a special at $659, and I jumped on it.

Brasf0311 Good lookin set of Super's you have there. I really like the Target Grey and would love to see Ruger use it more in the future!!! I still think I'd like to add a 480 SRH to my collection. I have a 9.5" SS 44mag and a 7.5" Target Grey 454. I probably don't Need it, but I Want it nonetheless I think if I were to be starting out buying my first SRH I would go with the 480 Ruger...? I'm not crazy about the Loooong bbl on the 44 and might just have it cut down to Toklat length of about 4.75" I'm kinda married to the 44mag with components, molds and such so I probably won't sell it to buy a 480...? But stranger things have happened I was reading more of Max's book "Big Bore Revolvers" last night and it makes me want a 480 even More! Anyone know if CDNN will be getting anymore 480 SRH's in and still running a sale?.? Thanks BigBore44

The newer SS model has a heavier/bigger diameter bbl than the older target grey guns? This I did not know....? BigBore44

You need to sign up on the cdnn website to get their emails or you'll never move fast enough to get the special price before the inventory is gone.
Yes, the new srh has a heavier target barrel. I believe Whit/Max posted about this when got one of the new guns.

I am already signed up at CDNN, I was just wondering if anyone knew if they were getting more in in the future... I just wasn't in a good situation when they had the last batch. Seems that happens more often than not LOL. Thanks again... BigBore44

BigBore44,
The new models have a full bull barrel right at 3/4", if my memory serves me well. The older models have a tapered barrel, that isn't drastically tapered to reduce a lot of weight, and most folks wouldn't perceive any difference from one to the other, but when you can compare them side by side, it is noticeable.
Here you can kind of see the difference in muzzle diameter and the newer crown also. The following pictures were borrowed from the cloud.
