What Does "GG" Mean?

[Treetop]

I've seen the abbreviation "GG" used here frequently pertaining to a boolit, but I can't figure it out and it's not listed here:

Thanks, Tt.

Don't know about "GG" but "GC" means gas check, referring to a boolit using a gas check.

[alamogunr]

My guess is that it is a typo. That occurs quite often on this and other forums. It even happens to those experts of expression, the media, more often than you might think.

[Roundnoser]

Not bullet related, just a little used fact: When I was in the military, we would say "GG"...which meant "Good to Go".

Gg-grease groove(d)

[theperfessor]

+1, the Grease Groove (as opposed to crimp groove) of a bullet. Well, most of the time anyway.

[Treetop]

Gg-grease groove(d)

Bingo, that sounds right, given the context! Thanks, swheeler. I wonder if a moderator could add that to the abbreviations sticky?

+ another on "Grease Groove", especially common among the jargon used by muzzle loaders.

My dogs name is GG, stands for Good Girl. She wouldn't tell me her name when she showed up here 3 years ago so I had to ad lib.

GG is guide gun

GG, Grease Groove, refers to cast bullets for black powder cartridge rifles using bullet lube as opposed to those using paper patches. I was somewhat surprised at the question since the great majority of shooters shoot black powder and the rifles made to be used with it, compared to the paltry handful of those shooting white powder.

Another vote for grease groove or Marlin Guide Gun. Actually, here we use lube groove
much more than grease groove, mostly because we spend a great deal of time selecting,
inventing, adjusting, fixing, modifying and discussing lubricants - and grease is too simplistic
a term.

Re: Gamma Globulin. In 'Nam, after a round of amoebic dynsentary due to a water filtration failure, the entire 11th Avn Gp received GG shots...next day, after morning formation, our company was marched past the flight surgeon's infirmary and anyone who wasn't limping was required to show his immunization record (we all remember those) to prove he'd received his shot.

THAT is a nasty shot! Like a hen's egg quantity of ice cold mayonaise injected into your
rump with a horse syringe - about a 1/8" OD "needle". Cold lump for hours. Not to be forgotten.

Grease Groove. As opposed to "slick" or smooth-sided boolits sometimes used for paper-jacket cores. GGGC would mean grease-groove-gas-check boolits as opposed to plain-based (PB) grease-groove boolits. PPGG means paper-patch-grease-groove boolits as opposed to paper-patched slick boolits.

I'm not sure why "lube groove" hasn't stuck, must be the black powder shooters keeping "grease" in common usage. Haven't seen "LG" used much as an abbreviation.

GG stands for grease groove-style bullet as opposed to PP, which indicates a paper patch-style bullet.

A paper patch bullet design will always have smooth sides ... without grooves.

Some people put paper patches on grease groove bullets.

That doesn't make them PP bullets.
They are GG bullets ... wrapped in paper.

[captaint]

Those Hensley & Gibbs guys thought is was grease groove. I guess now we call it lube groove. Mike

Oh, phooey!

We had to do something, since they didn't have the .270 Winchester, .30-'06 Springfield, etc. back in 1879 when all the laws regarding paper-patching were finally etched in granite. We tried smooth-sided boolits from home-made moulds, just like the classic BP designs but the patches just kept peeling off in the throat at velocities over about 2200 fps with smokeless powder. What to do? Somebody tried GG boolits and wet the patches so they shrink into the grooves and hold tight until the muzzle exit! Even a certain famous somebody that worked for the NRA long ago had Lyman make two different .303" moulds for paper-patching (designed to be sized to .001" over bore diameter), and they had grooves to hold the patch because they needed them.

Here's a paper patch boolit design that has grooves, I guess it's the first "modern" paper-patch mould that's been made in over 50 years. They're not "grease grooves" technically, though, I'd call them "retention grooves", and they're only .008" deep. I can call them that because I designed it. :wink: Works really well too!

I got my GG shots before I deployed to the Gulf. The size of that damn needle scared me more than the shot itself...Watched a couple of soldiers pass out just at the sight of it!

montana, that's the context that I was referring to, thanks.

[Treetop]

Can we agree that, for the Cast Boolit Forum purposes, the abbreviation, "GG" can have two meanings, depending on the context it's used in:

1) Grease Groove

2) Marlin Guide Gun

If so, can we have a moderator add these to the approved list of abbreviations in the "Stickies" section? Thanks, Tt.
