Largest / Most Powerful gun you've fired

[BigBill]

1. A full auto Thompson Chicago type writer.
2. A full auto m14 in 308.
3. A 700 Remington 338win mag.
4. Marlin 444S in 444 marlin. Drilling holes n 3/8” boiler plate.

Probably, and this is going to sound pathetic, a 3" magnum slug from one of my shotguns.

I made the mistake of buying high-brass 12 gauge shotgun shells by accident. It was, like, a buckshot geese load. I didn't realize they would have such POWERFUL recoil. My god. It felt like a horse kicked me. Wow! Never again. Never again.

[ACORN]

Some kind of wildcatted .358 Win-mag in a custom XP100. My wrist literally felt like I punched a brick wall.

 

[505Gibbs]

Handgun - 460 S&W.
In a rifle - 505 Gibbs - my retirement gift to myself!!

 

[SailDesign]

The GPMG on a 1970's SAS Land Rover (Pink Panther camo)

Probably only a 7.62 FN MAG, but quite fun in full auto mode.

FN MAG - Wikipedia

 

[OLDNAVYMCPO]

Largest bore would be M-203, greatest firepower would be M-60. Sporting arms would be T/C 30-30 in handguns, 7mm Mag in rifle.

 

[Kurusu]

.458 Lott. In a portable gun.

Edit. In case you're wondering. Didn't like it much.

 

[ISCS Yoda]

Fun thread resurrection!!!

In a handgun, besides a .44 Magnum, a .30 Carbine in Thompson Center Contender or a .35 Remington in a Remington XP-100. I can't recall for sure but I think the latter.

In a rifle it was a CZ-550 "European" in .416 Rigby. THAT was entertaining.

 

[Mr. Wonderful]

Hmmm... let me think.

Was it the Browning Auto-22 in .22 Short? No.

Was it the S&W 29-2 in .44 Magnum? Let me think again...

Was it the Sauer 202 Supreme-Lux in .375 H&H Magnum?

I really can't remember. I think my brain was a bit rattled after I shot the Sauer.

Best wishes everyone!

For the shoulder-fired category, it's the M67 90mm recoilless rifle:

For the "other guns" category, its the M109 Paladin 155mm SP howitzer:

For the handgun category, its the S&W 500:

And, finally, for the "all time favorite" category, none other than MA Deuce:

 

[hkcavalier]

120mm Rheinmetall.

Thompson Contender chambered in .45/70. As my old grandmother would say that is just too much sugar for a dime! I fired it the first time out of ignorance. I fired it the second time in the vein of "getting back up on the horse that th'owed me"
There won't be a third time unless something very very bad is about to happen to me. I mean it.

The first pic is a graphic demonstration of the difference in the standard .45acp and the .45/70. If you are wondering about the recoil of this round in such a light fire arm...well, there's yer clue.

I don't care how big and strong you are. I don't care which stance you use. You fire this beast and you will be takin' a couple of steps backward.

My Brother had a T/C Contender in .45/70. In factory condition you might get three shots off before you had to put it away. But after he put a JP Recoil Eliminator (JP Howitzer Brake) and a set of Rubber Pachmyr Grips on it, it was a pleasure to shoot, I could shoot it all day long then. The low pressure .45/70 Makes a big impressive low Frequency Boom, fun to shoot and fun to hear. Unlike my .458 Win Mag Pistol, which is much more powerful and hurt a lot more, but is was more of Loud “Crack” do to the high pressure/high intensity round, somehow not as satisfying as a big BOOOOOOM! of the .45/70. ;-)

If you equate powerful = painful the most powerful hand gun was a 14" TC in 44 mag. I was stupid and fired 2 rounds of my own ammo. I guess the first one didn't hurt enough. The same ammo in my Ruger Redhawk 7-1/2" was comfortable.

In rifle it is my Sharps Quigley replica in 45-70. Loaded with Accurate Arms 5744 powder it was robust, switched to AA2015 and redefined agony -- good news it was only 5 rounds.

 

[78bagger]

Twin mount, 3 inch 50 off an LST.
Handgun? .44 mag
Long gun? Ma Duece

 

[steelslaver]

Hand held would be an M79 grenade launcher or a laws rocket.

My brother was on a 8" howitzer crew. He loved his gun.

 

[walkinghorse]

.55 caliber Boys anti-tank rifle. Shot several times and did not care for it!
Over 40;years ago!

 

[Bakebfr480]

A 4 bore paradox!

 

[cowboy4evr]

10 ga magnum double barrel shotgun .

 

[MTC(SS)Ret]

I guess you wouldn't call it a gun but I threw the switch to launch a Poseidon missile from the launch tube on a submerged submarine back in my Navy days.

 

[Da Nang Seabee]

M2 .50cal. Didn't Fire it much but it was great.
