Semi auto and solid slug

[pheasant sniper 1]

There was no mention of it when I typed the reply I know what the script is with slugs I've been using them for years ,and yes there on my ticket .

Of course you are correct by using cylinder choke whilst using slugs .

Brenneke and (sabot slugs plumbata) which are plastic cased are made to compress through tight chokes where as solid slugs DO NOT compress , where in lies a loss of your sight a hand or death by a barrel blowing if your unlucky .

To be fair WS comments were fair given the op's post

The sabot type I should have put down at plumbata type which are plastic sleeved by a plastic type wad I'll see if I can find a picture of them they are very accurate .

I know the type you mean, they are very popular in America and very accurate through rifled barrels which in the states you can buy to fit on your pump or semi to make a fairly respectable 100 yard rifle. Just such a pity that such barrels would make a pump or semi in the U.K. section 5.

I was always led to belive the fins on the Brenneke were olny to reduce the bearing surface
of the slug to the barrel,in turn this would reduce friction and increase velocity





Where as the Pumblata Slug has a plastic stabliser attatched to the slug.

In rifled barreled bolt action shotguns in both 12 and 20 gauge with sabot slugs I've found them capable of 1 1/2" 3 shot groups at 100 yards .

With the older style slug barrels smooth bore cylinder choke with the plain old Winchester 12 gauge 2 3/4" 1 ounce slugs I've shot 5 shot groups from the bench with open sights at 50 yards from both Remington 870 and 1100 that were 2" . In some of my drillings with full choke in both 12 and 16 I've also shot some pretty decent groups at 50 yards with both Foster style and Brenneke style slugs .

If a fellow fools with ENOUGH slug guns he'll come to the conclusion that while there may be a few generalizations there are NO steadfast rules one needs to give it a try and make their own decision .

So you were searching to Bob, Wikipedia a wonderful thing !

Nice to be nice .

fins are there in an attempt to impart some spin and stability in the mass
the bearing surface of the lead is only a small part of the overall bearing surface

the fins also allow for any compression due to chokes

no slugs are cast like rifle bullets to be compressed in the barrel. they always have tolerance between barrel ID and slug OD (unless they are home made and you screwed up your casting!)
the fullest choke in a shotgun barrel is 0.04" (less than 0.5mm radially) more likely the chokes are as little as half of that.

I used some Brenneke slugs through a mossberg pump
impressive effect on an old Renault!!

Brewsher,I've was always told slugs were better fired in an open choked barrel
& to avoid Multi chokes. Saftey and all that ! nevertheless Thanks.

Rgds, Buck.

PS, you could'nt have picked a better Car !

we tested the theory of Hollywood cops hiding behind car doors!

shot a Renault Fuego broadside.
It went through the drivers door, drivers seat, handbrake handle, passenger seat, passenger door liner and punched a bulge into the skin about 2" deep.

next one went through the front wing into the engine, smashed the crank case and destroyed itself somewhere between piston and crank, taking a con rod with it.

nasty

I've shot Remington slugs through a Benneli M2 with 1/4 choke. If I remember correctly the packagin said recommeded 1/2 or less.

 

[bogtrotter]

Poor answer (what's a ordinary barrel ) full choke , three quarter choke ,half choke , quarter choke, improved cylinder ,there all ordinary barrels ,but I wouldn't put a sold slug through three chokes .

Acurracy with information like this could just save someone's life .

Would agree with that I have an old Laurona that had a slug put through the full choke barrel, the barrel did not burst but if you look down the barrel it is now nicely rifled at the muzzle.

 

[8x57]

How can it become rifled at the muzzle simply by firing a slug through it.

 

[simon1979]

i think id use an open choke myself. what would you be shooting if your useing a slug.
can you buy rifled slugs in the uk??, its something if never used. I know my grandad used them many years ago for the likes of deer but im talking 1940-50's.

 

[6.5rem700]

as far as ime aware [i may me wrong but dont think so] to shoot a solid slug from a shotgun you would need an fac for this ??
please correct me if ime wrong

Quite simply, while the slug may be softer than the barrel it has torn quite deep grooves into the barrel where it is chocked so much so the gun is now unsafe to use.

I should say rifled was just a figure of speech, the barrel is also slightly bulged you cannot really see it but you can feel it if you run your fingers down the barrel.

 

[simon1979]

yes i did think slugs came under section 1, but wasnt sure if it was just rifled slugs or type of slug. I wouldnt think these much need to use them either, but i may be wrong

Yes you need to have slug on your firearms certificate.

Grooves but not rifled. Obviously you didn't use the right type of slug e.g. Benekke which are designed to pass through all types of choke as it says in the link. Some types of slug such as the sabot type are really intended for use through rifled barrels while Brenekke type which are more popular in Europe as designed to be fired through conventional shotguns.


Edit.
I was in a rush when I wrote the above last night so didn’t put it quite right.
You say that the slug has left grooves at the choke of your Laurona shotgun bogtrotter are you mistaking streaks of lead for grooves? I can’t believe a soft lead slug will gouge a steel barrel. If the slug did not compress on the fins and you drove the slug through a tight choke surely you would have bulged the barrel but it is extremely unlikely that this would be in the form of individual ridges or gouges. Yes I know there are cases of over rifling on thin barrelled express rifles when the original Barnes type copper bullets have been pushed down the bore at high pressure and left a ridges in the form of the rifling on the outside of the barrels, but in the case of a shotgun the result is going to be a bulged barrel if there is a problem.

Wild Boar in Europe by Laurent Cabanau ...pages 114/123 gives some useful data on slug of different types/ballistics and choke recommendations....enjoy!

Good book Cervus, I have a copy.
