Had some fun on saturday smashing gongs with the 7mmRM and my anemic 6.5, got me thinking about sorting some of my own. Where is the best place to buy em from or does anyone on the forums make them?

Talk to Fletcher Easy Steel in Auckland. Had $2000 worth of plates cut from 10mm thick AR500 a couple of months ago for the club.
Ha ha :D
I got 12 different size gongs from a engineers in town for $50 he drilled holes for chains etc, they were just off cuts. nothing fancy, ya only shooting the things. From 400 meters to a 1000meters. Nice heavy inch thick etc, big bombs dont punch through it.
Its been said before, and I'll say it again, be very careful shooting steels of the wrong steel grade set at an incorrect angle to the line of fire ........... you put yourself and everyone around you at considerable risk.

Save yourself, save a friend, buy AR500 plate as a minimum, and set it up at a 20 deg forward facing angle to your line if fire. The cost difference of AR500 over mild steel plate is only a couple of boxes of ammo. Whats you life or that of a family member worth??
On offence intended by the above image - I would hate to see someone end up on the "incident" thread of this forum.
I got a couple made up from 20mm MS for 500 yds. Problem was the wind picked up just after I'd hung it up so I put 5 rounds from the 1917 into it from 100 and can put my thumb into the divots. Quite impressive to see what grunt 30 06 corelokt has.http://uploads.tapatalk-cdn.com/2016...3a205430e1.jpg

130 barnes at 3000fps at 100 :) 300 Rum with 208 amax don't even dent em at 100. Shit standing group ;)

If you're tight like me then try the scrap yard, leading edges on digger buckets, digger buckets etc, there are lots of things down there that're HT steel and only cost 60-90c per kilo, flick them a box of beers and they might gas them to shape and gas a couple of holes in them for you.
Just pulled out the price we paid for AR500. A piece 300x300x10mm was $41 each +gst.
Interestingly, we were originally quoted AR400 which was only $1.21 cheaper per piece.
This is very competitive pricing and they dropped their margin to low single digit so you would struggle to match this but, in the bigger scheme of things, plates aren't expensive.
Projectile velocity is the killer of steel plates, more so than bullet weight. Have a look at https://youtu.be/AX4AqkqQJg8
Ar500 is the business, punched loads of holes through 16mm stainless at 320m, only a very shallow dimple with the ar500. And it rings rather than makes a 'whack' sound so far easier to hear a hit at longer ranges
I just got an IPSC made up from Hardox 450 15mm thick.
What will this be able to stand up to?
I had the local engineer here chop up an old digger bucket, not sure what steel it is but he said it was a bastard to cut, its about 14mm thick and takes a pretty good thrashing hasnt really had any big cannons on it yet (270wsm and 300saum are biggest so far) but its soaked up hundreds of rounds from 270, 30-06, 223, 260, 308 etc, only cratering it has was from me "experimenting" what would happen shooting it at 100 with 270 and it put some pretty good craters in it.
Sure its not plastic? 270 denting steel....you're having a go :D
Ha ha go the 270
How are people organising the 20 degeee downangle ?
Could you get someone to weld a few single chain links onto the back of the plate and hang it from those ?
A photo would be interesting.
What's the need for the downward angle? Surely the gongs are in a place which is appropriate to begin with?
Downward deflection?
hardly any need for rifle work, whats the point of shooting a gong inside 400 meters at the end of the day??.... to see the dent in it or something
The 20 deg angle serves two purposes:
1. It ensures that the projectile splatters in a downward direction and into the ground rather than off to the side or up, potentially into an unsafe zone risking injury to someone.
2. It reduces the energy that the plate has to absorb when the projectile hits, therefore less damage to the plate, therefore your plates last longer.
The issue of uncontrolled deflection of projectiles is becoming more and more of an issue as awareness improves. Lots of pistol clubs have now banned the likes of poppers and falling plates that hinge backwards because competitors 'chase the plate' with rounds as it falls backwards resulting in and upward facing plate and projectiles skipping out of the range safety zone/back drop. They now only allow forward facing targets that fall forward when hit.
good info, thanks @hotbarrels
If the gong is hung near top it naturally deflects down
Yes, hanging off chains is an option and you can position the chain mounting points such that the plate will hang at 20 deg. The biggest issue I see with chains is the time it takes for the target to resettle after being hit. If the target is swinging then the 20 deg safety angle is constantly changing. Therefore it you do a rapid fire on the plate and it has swung to the wrong angle, then you have the potential to deflect a round to where you don't want it.
I will try and post some images of a target stand and mounting bracket that I have developed for our club targets. These are designed to protect the stand from all deflections and/or miss placed shots. The only surface visible to the shooter is the plate. This keeps maintenance to a minimum, and the setup and knock down is as simple as setting out electric fence standards.
Here's some videos showing typical ricochet issues highlighted by using tracers. Note the completely random directions for the rounds, even coming off the ground in the first video. If they weren't using tracers, they would have no idea where the rounds are going. Steels at the wrong angles are a major cause of ricochets.
