A query about Vang....

Someone from another forum asked me to ask this around, so...

He reports patterns from his Vang Comped bbl at around 12" at 20 yards. Is this close to standard? It's tighter than my unchoked HD 870, but not by a marvelous amount.

Also, the Vang process has left a rougher bore, supposedly on purpose. The slight retardation of the wad aids the pattern, in theory. But, my respondent reports that lead builds up PDQ when shooting especially slugs. Flakes of lead have to be removed afterwards.

Would all you Vangers(Vangees?) help him out here? Thanks...
 
I have an 18" bbl Vang comped police 870 that will keep 12" at 25 yds. It is true that the Barrel finish is a bit rough and collects lead - particularly at the forcing cone. Ive found that it is best to clean it regularly to keep build up down.

btw: I prefer the title of Vangster, Lol!
 
Here's how my Vang 870 barrel patterns out with Federal LE 132 00 (Tactical Buck #00)

5yds.---1"
7yds.---1.5"
10yds.--2"
15yds.--5"
20yds.--10"

Build up of lead is same or maybe a tiny bit more than with other barrels. I would suspect quality of lead and loading or velocities are a bigger factor.
 
I think mine runs under 12" at 25 yards with the Fed 00 reduced load. That is hardened shot with buffering. Soft shot, or unbuffered payload, might (1) cause more leading (duh!) and (2) deform more and therefore spread more. I've got the targets around somewhere, but I think my memory is right here.

I blew a huge number of slugs and 00 loads downrange one week this summer and did not notice any unusual leading, but we were using the same Fed 00 loads most of the time. (Those reduced recoil slugs are something else -- you can actually watch that ol' pumpkin go downrange.)
 
Well, Vang must have put an apprentice with a dull cutter on my barrel, because what Dave describes is exactly what I get. And that's with the highly overrated Federal 00 "tactical" (meaning they charge more money for less powder), and the leading is just as bad with any of the big 3's standard velocity 2 3/4" slug.
 
Thanks, Vangsters, I think this will help out. A note tho....

Most of the old smiths I know say that the best bore polishing is done by shooting lots of rounds through same. Keith mentions the same thing in his classic work. I wonder just how long it would take for that Vanged cone and choke to smooth up. Any of you guys got more than say, 1000 rounds
or more?

Also, buffering is perhaps the biggest advance in tightening patterns since Fred Kimble invented the choke. Hard shot, plating etc, all don't show the improvement that the buffering does.
 
There are a lot of theories about how a choke works and most of them are probably wrong. The Vang Comp System uses techniques that are well known and have been used by trap shooters for a long time. You should understand that the main purpose of the Vang mods is to produce smaller patterns with buck shot. It does that very well. It also allows the use of any other ammo that can be fired in a 12 ga. shotgun, something that you probably shouldn't do with certain screw-in chokes.

It should also be understood that the Vang Comp System was designed with law enforcement in mind. The idea is to increase the effective range of buck shot and reduce the chances of collateral damage. In other words, put all the pellets in the target. A pellet that misses the target is not a good thing.

Regarding the finish of the bore. I saw some of the original Vang Comp barrels when they were bored by hand. Let me tell you, they looked like an old stove pipe, but they sure shot good. For a while, they put a 120 grit finish on the bore, but it was found that a rougher finish worked better. It has also been found that a fouled bore tends to shoot tighter patterns with buck shot then a clean bore.

I have talked to Hans about his barrels and there is one thing that I find interesting. Of the hundreds of barrels and shotguns he has sold, not one has been returned for a refund. A few barrels have been returned because the owner didn't feel that the patterns were tight enough, but no one has ever asked for his money back. How many businesses can say that?
 
In a sport that is rife with any number of money wasting accessories, most of which just blow a hole in your wallet, I have found the VANG Comp system to be one of the FEW things really worth the money. My 18" 870 Marine Cyl barrel now shoots 1 inch groups at 7 yards, has considerably less recoil and muzzle flash and has never dissapointed me.

I consider it THE best money you can spend on a tactical shotgun... Hell, I might even shoot some trap with that stubby little 18" barrel!

Thanks a lot guys. I'm still undecided about how needed a Vang job is, but the preponderance of user input is quite positive.In fact, this is probably as non contentious a subject as we have.

Ben, too bad we're on different coasts. A mano a mano showdown at 16 yard trap between your Vanged PM and Frankenstein would be interesting and fun to boot. We could do an article for G&A, throwing scruples to the wind(G)...

I can see the leadin....

12 ga SHOOTOUT!!! Vang Custom vs the Loudenboomer SP Mag. WHICH IS BETTER?

Then after 3000 words(duly compensated at the going rate) and some pics, we state they're both great shotguns and a boon to civilization as we know it.
 
My Vang 870 shoots about 10" patterns at 25 yards with Fed Tac OOB and 6-7" patterns at the same distance with Remington's 8 pellet reduced recoil OOB. Some of the Remingtom RR OOB patterns have been as small as 3" at 25 yards (with witnesses) but they average 6-7".

I have also noticed the problem with the leading but it cleans out pretty well with copper scrub pad material wrapped on a bore brush (as recommended by Hans).
 
Dave, if you want, I will mail you my 18.5" 870 Vang barrel for T&E. Seeing is believing. :-) (This is a serious offer.) Email me off-"list" if you are interested.
 
About 1/2" per yard is about right with Vang.

I think the best way to buy a Vang Comp shotgun is to watch his web site and buy a shotgun or barrel that has been already done. Usually, its seems that he has some surplus that he puts on sale. Perhaps extras from a big job.

Cheaper than buying the gun separtely and sending it to him.

Its suppose to reduce recoil somewhat as the shot and charge don't get bunched up. They move through the barrel easier. Its hard to tell though.
 
Some folks claim that the Vang backboring reduces velocity significantly, but others say that the Secret Service and other agencies or testing labs have found only minimal loss of velocity or penetration. I'd like to know more about this issue. Has anyone tested velocity with and without Vang? You already have some velocity loss with tactical buck ( with the trade off of tighter patterns), so if the Vang treatment reduced velocity further it might affect stopping power.

edited to correct a stupid spelling error.

I'm no ballistics expert, I'm just a dude with a shotgun. IMHO you would have to reduce velocity *A*LOT* to reach a point where it would affect stopping power.

Its kinda like being hit by a train doing 50 MPH as opposed to 60 MPH. In the final analysis, you still got hit by a train.

Coronach, I agree, I've read that the wad alone can shove you back more than a couple of inches...and convinced as I am now that bird shot WILL work in home defense (I can't imagine how they would repair a birdshot wound, the buffer alone...yuck) I can't imagine "reduced" buckshot, whether reduced by Mr. Vang or by Mrs. Estate as being short of a manstopper round.
 
Well...

Simple physics would suggest that anything that can forcibly push a target back a few inches would do the same to the shooter (well..I guess my shoulder recoils a few inches. Depends on what you meant, I suppose).

Remember, "Dumb" and "Dumber" recently taught us that cigarette butts can kill at HD ranges. :rolleyes: So, I imagine a shotgun wad will do much the same. :P

Other work besides 870's

Romulus if you get something other than a mossy or rem be prepard to wait for a while as vang sends out his benelli's to GG&G for the benelli barrel to be changed they keep the reciever part and add a new IIRC Shaw barrel to it. I just got mine back after 19 months this month. My first one was an 870 and was back really quick.

Went to phoenix show this last weekend and a guy from maricopa tactical said gg&g will wait till they have a whole pile of benellis then do them all at once hence the sometimes long wait. Hans told me he is going to try to work on making things speed up in the future.
