Not sure if I responded earlier but thanks to Bob, aka Reed338, I got to shoot a 338 Winmag IIRC, closest to that, what just about everyone on this forum owns, a Mosin 7.62X54R..

Honestly, I'm surprised we have no former military here talking about shooting a 120mm tank gun, or a 155mm howitzer...

 

See post 44

Does a 90 mm recoilless rifle count ..........

Does a 90 mm recoilless rifle count ..........

 

... Or a 4.2" mortar?

 

.50 caliber Ma Deuce on full auto. Good times.

Does a 90 mm recoilless rifle count ..........

 

If we're counting that, I've fired 90mm recoiless, AT-4, LAW, M203, M2 BMG. All live HE rounds.

 

Never fired any modern cannon or even a single HE mortar round.

30/06 in an 03 springfield prone when I was 12 didnt have it tight had one hell of a bruise

The usual infantry stuff, .50 M2 machine gun, dragon rocket launcher (tow like wire guided), RPG9, MK19, m203

105mm stabilized rifled cannon while moving at 30mph.. And hitting a vehicular target.at 2000 meters . at night.. mounted on my avatar...muhahah!

 

I've got a very cool one-day-a-year (July 4) part-time job as a pyro crew chief for a local fireworks company.   The mortars for the hand-fired shows top out at 6" diameter, shells lofted by black powder lift charges.

 

The finales are chain-fused together, which I guess counts as 500+ mortars firing on full-auto.   

Double barrel 12 gauge shotgun/.308 combo on top.  That woke me up that day!

82A1 Barrett

Biggest handgun was A S&W 500. Center fire .45 colt. Now muzzleloader is tricky. .58 navy arms hawken but have shot a .69 cannon and in my 12 gauge muzzleloader I shoot a .714 round ball out of it.

Handgun - Magnum Research BFR in .500 S&W

 

Long gun - either my H&R HB2-500 Handi-Rifle (.500 S&W)

                   or my Wessson & Harrington buffalo Classic in 45-75

 

 

I have shot the Serbu 50 BMG but not on a regular basis.........

.500 Jeffery w/540 gr Norma solid.  Sucks.

I got to shoot a .50 Beowulf this weekend... I must say, I've been pricing out the costs to build one most of the morning....

I got to shoot a replica Sharps 45-70 and on my 4th shot hit a 18"x18" steel plate at 500 yards with the iron peep sights

300 win mag

Either a .338 lapua or a .50 Beowulf. Depends what you consider bigger

My dad was a DI at Dix and I was able to shoot m60s as a kid.  I've never shot anything more powerful than 30-06/.308 but did get to throw a grenade one time!

7mm Mag....once, and never again.
