I have a steel gong at 100 yards for plinking. 6mm Hardox (I believe. )
Anyway. It already has a couple of holes from my 243 and 308 , so has become the sacrifial gong.
Mate just turned up to sight in his 7-08, and having got it shooting to POI, he put a couple into the gong.
Thing is, they only dented the bugger. :wtfsmilie:
Now as far as I can tell from the numbers, that just should not happen. Whats the story?
Point of AIM, dumarse
Using armour piercing in the 243 :)
Not quite. 85 Nosler spQuote:

Probably hit the quarry truck on the way down to the gong ....
Shot angle? Hit low so swing took impact? Gay 708?
Who are you calling dumb arse, dumb arse?Quote:

Pengy, having failed School Certificate twice (the second time with distinction) I can absolutely tell you that the answer to your question lays in the diminished area of impact and the rate of transfer of energy on impact. You heard it here first.
Now knowing that you are slow on the uptake, I will give you an example. Think of your hand as a gong. You put your hand on the floor, palm up. Rushy jumps on your hand with the heel of his boot from a chair (this is the 7-08). Your hand hurts (is dented) but is not pierced. Now Gibo (who is there or there abouts half of Rushy's weight) jumps on your hand from the same chair but Gibo is wearing his wife's stiletto (as he has a tendency to do on a Friday night) and he lands the heel right in the centre of your palm (this is the 243) and Bob's your nana, a neat hole in the hand.
Too fucking right uncle but replace hand with flipper ;)
That story puts the shits up me, I hate the thought of a punctured hand, have stabbed myself with a Mercator right in the middle of my hand (palm side) whilst cutting the strings off a bale of silage before and while it was only a small injury it hurt like a bastard and made me get shivers down my spine whenever I felt or looked at itQuote:

2. Velocity is the killer of steel gongs, followed by bullet construction. Anything traveling over 900m/s will cause damage, regardless of calibre. At slower velocities, the blunter the bullet construction, the greater the damage.
3. irregular heat treatment, or heat treatment that had been tempered through high temperature cutting and/or welding of the plate causing soft spots. Get a hammer and a centre punch and test the hardness of the surface of the plate - it will tell you if you have soft spots.
I did wonder about that but I'm not a fucking scientist GM. I have another theory though and it goes like this ....... the 7-08 was useless and belly flopped onto the gong.Quote:

probably using shit 708 fusion ammo.better off using a slug gun..
Usually it is speed related rather than bullet/or caliber.
whats going out of the 308 how fast vs the 7/08 ?

Pengy come to the Toby shoot. Gibo and I have been talking and we want to give my theory a go from the top of Brads' wool sort table.
How close did the 708 hit the the original holes?
Could this have something to do with it?
That's pretty lethargic so would suggest that is probably the answer.Quote:

brain storming here maybe if you wear stiletto,s when shooting off the 7hoe8 you might feel better about it or if you get pissed about the result you could kick the hell out of the gong and put a real dent in it
food for thought himmmmm#%!?:sick:
