New guy with an old question.

I'm wondering about paper patching.

I designed a big bore cartridge, the 675 DNR. Cut a 50 BMG shoulder off and seat a 0.671 boolit. Almost a straight wall, just factory body taper.

It's that easy.

I have planned on a 0.675 smooth bore about 18" long.

Would paper patching be a good idea or just make bigger boolits?

Thanks on advance for the heckling.
 
#1...Main use will be for knocking scale out of boilers. They use 700 NE now.

#2...Who else has a smooth bore firing a BMG based cartridge?

#3...No one wants to build a rifled barrel for less than $2K.

#4...I'm not going to be shooting groups. If I hit the back stop, I'm happy. (Who wants a 675 to get away)
 
...or just blow the case out straight and build a 12ga From Hell. Cartridges of the World lists it, and a South African .700 variant.

For US shooters, the ATF's position is (circa 2009-ish when I checked) that if the gun was originally designed to shoot a shotgun shell, it's a shotgun even if you have a rifled barrel and a bullet, and therefore is not an over-.50-caliber "Destructive Device."

Years ago someone on the Accurate Reloading forum observed that the base of a .50 BMG and an ordinary 12ga shotgun shell was very similar, which resulted in several forum members shouting "HOLD MY BEER AND WATCH THIS!"

I bought some of the first run of 12gaFH brass from Ed Hubel back in '07 or so; the ones with the CNC machined rims screwed onto .50 BMG brass. I gave one to a friend who owns a Barrett .50; his reaction was "Are you NUTS?"
 
Don't Winchester/Remington still make kiln guns?

I now Winchester leases the gun and sells you the 8 gauge ammo - it's what we used after wearing several 1100s shooting slugs. Gun is mounted on a tripod
