Gorilla Checks

we all know that gas checks work ..

so wouldn't better gas checks work better ??  after all, a nosler ballistic tip is really only a cast bullet with a real long gas check ...  i only shoot bare naked castings, believing it heresy to shoot partial-jackets in a cast-bullet match.   although come to think of it, i have never shot in a serious cast match either ... but let me continue without thought  ....  

has anybody tried really really thick walled gas checks ??    i am thinking that for a 30 cal, i could machine out some ( 0.310 - 0.125 ) = 0.093 wall gas checks that would fit on a bullet that had a 0.125 shank on the back .  being that i have a bunch of aluminum left over from my working days, that would be my first material.  i have a hobby turret lathe that could whip out a handful in a day if someone with an accurate rifle has interest. pm me.

while we are at it, how about a 3/8 long gas check, real thick base ... i have 2 or 3 110 gr molds, might wind up with a front heavy, 3/4 inch long 115 gr, 30 cal, gorilla checked bullet.

*************

no doubt against some match rule, but this is only for purposes of homebrew bullets that shoot well.

and to test the idea that more is better.

***************

or, have any of you obsessive match shooters machined " standard " gas checks, looking for better bases and fits ??

****************

the above comes from me finding some old targets from my serious days that show improvements from lathe turned ( perfect, at least before ignition  ) bases, and my squisher dies that probably mostly squared bases .

Isn't that about the same as Speer Plinkers a n Hornady Half Jackets? Both 30 caliber.

That was my first thought beagle. The old half jackets.  Give it a try Ken. We have to have something to tinker with on our toys. Retirement is great, having the time for projects. Gp

yep, kinda like the commercial half jackets.  speer plinkers are still available, at midway for $0.13 ..

btw, midway has remmy plinker 22lr for 3 cents today .    gas checks seem less complex than a complete cartridge for the same price.

i suppose commercial half jacket bullets are a little cheaper because they don't need a nose forming op.  long ago i bot 2 or 3 hundred 30 cal for my 30 carbine but i think they didn't shoot as well as my standard mj.  i read back then a reason why, but thought maybe modern techniques might improve the results.   just to start, the lead nose looks very undersize.... wouldn't work for a 3118 either.

thanks for comments.  ken

Geez,

It's a blasted conspiracy to make me feel old today.

The Direct-TV tech installing new HD Rcvrs looks like He's a 110yrs old

I just talked to the Lodge Treasurer who's 79yrs old, known him my whole life, Last Lodge Member present when I was Raised in 1976, 43 blasted years ago.

Now you guys are making me recall pouring cores for half-jackets back in the 1960's. Think I got a box of 38 jackets buried somewhere in the garage. they'll find 'em when I'm gone. Along with Noah's Ark.

What's next ?

Long time Caster/Reloader, Getting back into it after almost 10yrs. Life Member NRA 40+yrs, Life S.A.S.S. #375. Does this mean a description of me as a fumble-fingered knuckle-draggin' baboon. I also drool in my sleep. I firmly believe that true happiness is a warm gun. Did I mention how much I HATE auto-correct on this blasted tablet.

I could never get the half jackets to feed reliably in my M1 Carbine either.
