Hi Vietnamcam, Thank you very much! as per my pm, just let me know what the postage etc is.
The gong arrived yesterday, I had expected a simple bit of metal with work still to do.... what I got from Vietnamcam was the finished product! really chuffed and thanks for doing that for me.
Sweet as
Steel arrived, was a laugh, 480 staff at my work. Store guys were trying to find "gunshot" thank you
hey guy's i'm looking to get some Bisalloy steel for shooting anyone have any spare or for sale been looking everywhere and can't find any cheers. :yaeh am not durnk:
You good bastard @veitnamcam
As long as the steel has these properties, you'll be fine. Bizalloy/ Hardox etc is brand name as far as I understand it. The harder steel is not more expensive than mild. Hard steel generally secure a complete disintegration of the bullet, mild does not. Thicker steel is not more expensive either, but you will pay more for it as steel normally is sold by the kg (at least here)
Hardness HBW 380 or more for 12mm, 425 or more 8mm plates
Typical yield strenght 1100 - 1300 Mpa.
The main difference between armour 500 plates is that their yield strength is guaranteed, whilst non-armour steel doesn't guarantee the yield strength - just sample the lot. For a shooter, no difference or consequence if he gets a bad lot and a bullet goes through.
You can get some ideas for cheap, durable stands here

Here harder steels are a lot more expensive by weight than mild steel.
Hardox and bisalloy are brands but the two are different steels,hardox is more dent resistant and is designed for the likes of a rock deck on a tipper truck(to resist denting from rock being dropped on it)
Bisaloy is more designed as a work hardening wear surface and is exceptionaly tough as well.
What it means for shooting at, is there is basically no difference between them for shooting at.:thumbsup:
Highly recommend using "400" plus for shooting at as it is hard enough to splat the bullet and it all goes at 90deg to impact, mild if thick enough to resist penetration will crater heavily and send bullet or parts of back in drirection of impact,this is bloody scary! and dangerous.
Not so much of an issue at long range but certainly something to be aware of :)
Well put. Mild steel can also leave larger chunks of bullets alive with significantly more energy potential than the usual 5-10m "spray" (mostly downwards if plate is hung) if it is hard steel.
Some of mine are 12mm mild steel at 10" rounds , 208 A max sprays of them leaving a grey splash 600 yards VLD will deep crater at that distance . both projectiles go right thru 12mm mild from a little under 500 . Al tho i have done i don't use any of the mild gongs under 900 VLD's will still give them some cratering at that range . Generally all i need do is fresh coat of paint make'm almost new again ,at 900 up for me they perform almost as good as the Bisaloy gongs , and cheap as chips some thing like 5 bucks a plate cut . i will say im not recommending using the mild but just saying i do and have found they work ok at range .
Just getting prices for gong was thinking the following
450x450 square with 2 x hole at top for a shackle for hanging
Material bizalloy 400 @ 16mm, (quote has wear 400, so must be a similar material)
also have an option for 20mm (extra $30 tho and 6 kg weight)
Not a permanent set up and wanting size to 'see' where the rounds end up
Thoughts and experiences ??
Ta
Those plates of mine that you have shot, are 500x500 12mm hardox 450. Nothing has ever marked them. Bullets just disintegrate and spash on impact. When painted white, you are left with a very visable dark grey splash mark which is visible thru your scope out as far as ive ever shot them, 700 yards.
I really like the larger plates, we just spray a 2" pink bull on centre of white background. The larger plate easily lets you see where you are hitting and you can adjust accordingly, rather than potentially missing a smaller plate and maybe not knowing 'where' your bullet went.

Funny this thread got new life, in a few days I'll be looking at gong, freight is going to be a killer for me though so will see what eople have lying around. Think I know of an old tractor front end loader that could be used.
