Not Lugs.  Are Plugs.  Plugs keeps Water and bugs out of the bore.

 

 

Not the tompions.  There are three lugs at the muzzle.

Sixgun is close to correct.  The lugs anchor the tool that is used to remove the replaceable rifled sleeve in the gun tube. 

 

Thanks.   I thought that they might have something to do with some sort of barrel replacement,  but I couldn't see a barrel that size being screwed into a receiver.  Didn't know the liner was replaceable,  even though it makes perfect sense. 

 

Most be a heck of a thing to see.

comparing to the M110 8” SP howitzer, the naval barrel is about 15” longer, the projectile 138 lbs heavier, the rate of fire, 10/minute vs 2 min per round. Range is about the same.

 

numbers are likely a little off because Wikipedia does not differentiate between m110a1 and m110a2

 

our howitzers were usually no combat ready because the barrels were too old, all the good stuff was going to SE Asia.

And to think my mom told me being a smartass would get me nowhere. :D

Are the powder cases reloaded on board, or stowed away and returned to shore?  Are those brass?

Can you reload those powder cases and does RCBS make reloading dies?

What size primers ?

 

Dillon made a progressive press.

 

Primers?  Why, obviously you would use Large Rifle primers. :D

And you thought they were bayonet lugs.

 

I think the japanese were the only ones to put bayonets on guns that big. 

 

I figured the primer was just a 30-06 round.

My father was a Navy Gunners Mate Warrant Officer. We had an ashtray made from the base of one of those 8" shells and as a kid I got to polish them on occasion. So at least some of them were brass. As far as reloading them I don't know and never thought to ask.

As a kid I went on the U.S.S. Boston. They had 8" guns at least I think the first 2 up forward were still there but the rear had been removed to make the ship a guided missile cruiser. I got to go into one of the magazine rings with my dad. This was about 1960 or so.
