So far, everybody else has offered brute-force sollutions. I'll bet this is
faster and easier. Center punch the center, draw a circle 7/64" smaller
than the finished hole, prick marks on this circle 1/8" apart, use an air
drill and 1/8" stub bits and drill these holes, knock-out the slug, clean-up
with a tapered reamer, finish with a sized reamer.

If you are really careful, a .243 winchester will make a nice
.308-315 hole in a frame. Might have to grind off a little crater wall

I once shot a nice hole through a railroad tie plate with a 7.62x54R
Mosin-Nagant rifle.

So how do you deal with the "Come-backs" in this situation if that
bullet decides not to punch through but to bounce?

It's bad enough trying to punch concrete nails into seasoned
underground garage ceiling slabs with a Remington .22 and having the
nails hit the first chunk of quartz gravel and make a U-turn. After
the first two bounces you give up and get the drill.

I don't want to think about a bullet bouncing back...

Only pistol bullets bounce back. Rifle bullets..now you may get a
spray of fragments..generally splatter from the steel target, but
rifle bullets break up. We are not talking AP here..cupronickle
jacket with a lead core.

Making sure other people play nice and dont kill each other (and us)
off in job lots is hardly empire building, particularly when you give
them self determination under "play nice" rules.

Think of it as having your older brother knock the **** out of you
for torturing the cat." Gunner
