checkin for steel proofing

[jigga]

is there any way i can check if my gun is steel proofed ? its a bakail o/u ejector ( not sure of model ) also the barrels are chrome lined. cheers

If it has the above symbol and the words 'STEEL SHOT', then it is proofed for steel.

cheers trussman il have a look.

Hi. My Miroku (MK70) has 'special steel 12GA-2 3/4 and 3' written on the barrel. Could someone be kind enough to explain what that means?

[clayman]

Very few manufacturers of modern guns (if any) make two versions, one designed for steel proof and one not.

 

This is really an importer / distributors choice, it costs about double to have a gun steel proofed, so some are and some are just lead proofed - but chances are the guns are exactly the same off the production line.

 

So, if identical models to a lead proofed gun are also available steel proofed ( usually about £50 more to reflect the higher proof charges), the guns are almost certainly identical and the lead proofed one will be perfectly capable of taking steel and being steel proofed if you wanted to submit it.

Thanks clayman. Do you know what the script on my gun (appearing on my previous message) means?

Your miroku MK70 is steel shot proofed, As a rule all Miroku'sBrownings,Berretta's,Lanber, and even now the new model Lincoln's come proofed for steel as standard.

 

However when I mean proofed for steel this generally applies to 3" High performance steel loads, as discussed many times on here you can generally put anything up to 32g of steel through any gun up to half choke.

 

The higher steel proofing as a rule of thumb take your gun up to 1370 bar where standard lead proofing ran at around 1050.

 

As clayman has stated many guns come off the same production line but for obvious reasons are not proofed for steel. such as the case of Miroku or Browning trap guns (either a MK38 or 525 for example) because they are manufactured with too tight a chokes for steel.

special steel 12GA-2 3/4 and 3

 

Well, there are three statements here:

 

12ga = we know what that means, 12 bore or designed to take 1/12 of 1lb of lead in a ball down the barrel

 

2 3/4 and 3' = chamber length, meaning it will take 70 and 75mm cartridges ( open/fired length)

 

special steel = a Miruko sales naming , just like your car may have GT, or turbo or tdi on it, really just some meaningless manufacturers jargon.

 

American guns ( and Jap clones) are subject to manufacturers certification of proof, via measurement and batch testing, in their country of origin.

 

Countries in the CIP Proof agreement all subject every gun to destructive testing, 30% overcharge in it and either it blows up or it passes.

 

CIP English or EU marks of proof, steel or otherwise, are therefore added at the country of import to a Miruko. These are very meaningful, as they state what an independent tester has tested the gun for, while the manufacturer's marks more or less say this is what we have designed the gun to be OK for, and some others we tested a while back were ok, so this one probably is too as we made it the same way.
