Beretta S686 and steel Carts

[Agriv8]

Google is not giving me a conclusive answer.

i have an old 686s that I was thinking of thanking as been invited down to the ponds before beating in a couple of weeks.

So as we are over water steels are the order of the day.

I could take the 725 but as I will be taking the beretta for the rest of the day 

any help appreciated and if in doubt I can nip and see my gunsmith but don’t want to trouble him if I don’t need to.

barrel markings

Thanks Agriv8

Your chokes are full and 3/4 ?

Wont be steel proofed and you need to look at the marking on the side of the barrels to determine the chokes.  Here are the markings on my S686 Special I have circled the choke markings 1/4 and 3/4 in my gun (had it confirmed by a gunsmith, as they've often been opened up).

Never shot steel through it though.

It’s Mobil chokes IIRC and currently running 1/4 and 3/8 ( teaque s ) iirc.

i will have a look at the pdf from basc when I can find something that will open it !

Here you go;

STEEL SHOT
What you need to know from a safety point of view
There are two types of steel shot cartridges: Standard Steel and High Performance
Steel (See table below for criteria). Standard Steel cartridges can be fired through
any gun proved to the standard level (ie most “Nitro” proved guns, proved to at least
930 bar) and through any choke. High Performance Steel cartridges should
always be marked as such on the box and should only be fired through guns
that have passed Steel Shot proof. These guns should be proved to at least 1320
bar, be stamped with "Steel Shot" and a have a Fleur de Lys proof mark to prove
it). Most High Performance steel can be fired through any choke, but it is
recommended not to use choke greater than a half for shot sizes BB (4.1mm) or
larger.
As a result of its hardness and the typical plastic wad, steel does have the potential
to cause some choke expansion ("bulging") particularly in older, traditional lightweight
guns. Care is also needed when shooting steel shot as it can ricochet more than
lead. Eye protection may be sensible.
The descriptions and limits are set out by the International Proof Commission (CIP)
for 12 bore guns are:
Type
Chamber
Length
(mm)
Max Average
Service
Pressure (bar)
Max Velocity
at 2.5m
(m/s) / (ft/s)
Max Momentum

12 3.25

High
Performance 73 to 76 1050 430
(1410) 15 -
High
Performance 89 1050 430
(1410) 19 -
"Steel" shot is really soft iron. Its density is about 7.8g/cc (compared with around
11g/cc for lead shot) and it is much harder than lead - consequently it needs to be
contained in a robust wad (usually plastic) to protect barrel walls from scratching or
wear. Its lower density also requires some adjustments to be made to the choice of
cartridge/pellet size for each type of shooting as low density shot (size for size) does
not carry the same energy, or for as long, as lead shot. Therefore it is recommended
to use steel shot at least two shot sizes larger than you would use in lead.

Sorry mate didn’t realise yours was a multichoke!

[motty]

I would put any steel cartridges through it, of the appropriate length.

Thanks chaps will have a check This eve when I get home. The carts are not HP steel link here :-

https://www.lyalvaleexpress.com/product/steel-game-32-grams-2/

will check proof marks asap

thanks

I put a lot of those very cartridges through a standard Spanish SxS 2 3/4 inch (70 mm). No problems since the lead ban on ducks/geese, and that is 21 years ago.

[Agriv8]

Ok well found the proof marks and looks like I am good for up to 1410 but not sure what Ksi stand.

thanks Agriv8 

Second look it’s kg 1410

 

Assume this is the proof house

[London Best]

I THINK the Kg 1,410 is the weight of the barrels, not the proof pressure.

Just use it! It won’t come to any harm at all.
