steel

Does anyone think that a .30 cal going 2900 will go through a 1/2 steel plate at 100 yards? Everyone else so far has told me no.
Thanks

Re: steel

Depends on the bullet and the steel. I almost punched through a fat 1/2" mild steel plate with my 30 Gibbs. This launches a 165gr SST at 2950fps. My shot was at 200yds.

If you use something like a Barnes X, I think that penetration should occur. Maybe even the SST considering the bulge and stretching the shot above caused.

Only one way to find out...

Re: steel

Mild steel... YES. A 308 150gn match will.

500 brinell steel I think will take it, unless you're talking about Barnes solids.

A 338 300gr SMK at 3000 fps will burn holes right through at over 500 yards and dent em good at 1000yds in 1/2" mild steel... food for thought.

Re: steel

Thanks guys, the bullet is a 220 gr MK from a .300 Wby. I will only shoot it at 100 yards. Oneone today said his cousin shot at one and the bullet came back and killed him. Then again he was shooting at rocks too. [img]images/icons/frown.gif[/img]

Re: steel

I shot a 300 WinMag with factory 180gr CoreLokt bullets thru 3/4" mild steel plate at 100yds. I've also shot my 300 RUM with 190gr SMK's going 3200fps at 3/8" 500 brinell hardened steel plate at 300yds and but a tiny and I mean tiny dimple was all that happened.

Re: steel

I guess It all depends on the grade of steel you are shooting. I shot 180gr partition from 300 ultra and it went right through 1/2" at 200 yards.

Re: steel

Depends entirely on the steel. US military uses 3/8" 40 Rockwell C for pop-ups, using 5.56mm.

Hunting bullets will penetrate mild steel at given velocity/momentum,etc. 40 RC is different.
