Larry Gibson is a genius

[james nicholson]

I tried the gas check in the lube groove trick that Larry brought up. He was spot on, I now can cast wad cutters for my worn 303 British. As usual Larry was on track and helpful. I now have a mold to make .3145 94 grain wad cutters.

The tricks these long timers come up with can be very ingenious and do solve a lot of problems with very little fuss. It pay well to pay attention.

I , too, commend Larry for his diligence and effort in making our hobby safer and more enjoyable.

james nicholson,
you should post a more thorough description of what you are talking about...
...or at least a link.

Indeed a clever idea. I'm going to make some just for the fun of it.

[Tom W.]

I suppose I'll have to try it, too. I have a NEF 30/30 that I haven't fired in years....

Nothing genius about it, you guys just don't read enough. Here's another article on it.

Another trick that's is different in that it's not to make a wadcutter is to use gascheck or copper bands in a mold placed in the mold where the bearing bands are to make the bullet stronger and be able to shoot high velocity with accuracy. It's all explained in the NRA Cast Bullet Book. If you use gaschecks you have to put a hole in the center of them so the alloy can flow through it.

Read more guys, read more!!!!

Yes Sir, Larry is the best !:bigsmyl2::bigsmyl2:

[swheeler]

He sure is!:drinks: With all the help he has given so many I'm surprised he has been given the "Golden Bullet Award". He's earned it!

"If a lighter weight mould was not available slip on GCs can be pre-heated in a tin lid on top of the furnace and then with tweezers one can be placed in a drive band groove in the mould with the cup facing the sprue plate." --

That's pretty slick!

[Larry Gibson]

Not a "genious" guys, just been to 3 county fairs, 2 hay rides and a hog killin' is all.........

I learned that "trick" many years before Sixgunner magazine was 1st published. Don't claim to have thought it up either. Probably was thought up long before I started using it. Notice if you read the Sixgunner article it is using a large 45 cal mould, not a common 30 caliber or any caliber mould as I suggested. Note the Sixgunner article is using crimp on GCs which means they stay on the WC, the WC needs to be sized and then is shot being good for one use only. That is unlike where I said to use slip on GCs. Those can easily be flicked off the WC and the GC's reused multiple times. The produced WCs also usually don't need sizing and can be simply TL'd and shot "as is". Lastly the article does not tell you about pre-heating the GCs in a tin on top of the furnace as I did which with smaller caliber bullets produces less wrinkled rejects. All things I learned many years ago.

Just enjoy the tip guys.

I am still waiting on his book.

[Boolseye]

I’ll join in on hailing Larry as one of the most astute and knowledgeable people on the board. He has helped me on several occasions as I learned the craft. Don’t forget, some of our members had to learn this stuff the hard way-we get to benefit from their experience. Thank yous are in order.

I posted this sometime back and it was created the same way. I had learned about doing that many, many years ago but forgot about it until a friend refreshed my memory.

Great tip, thanks Larry
The finished w/c they show is screaming for a gas check on both ends.
WHY ? don't no, just seems it would look cool, may not even need lube.
Whatcha all think ? or should I leave a perfectly good wheel alone and invent sum thing else.

[JSnover]

I really want to try this. I don't even know why.

[Larry Gibson]

"The finished w/c they show is screaming for a gas check on both ends."

Yes, it is if it was cast with a bullet designed for GCs. However, at the low velocity I recommend (750 - 900 fps) they act pretty much like a DEWC.

If cast in a PB'd mould I use GC'd formed part as the nose and the PB as the base.

[JSnover]

Using the check to turn your (any profile) mold into a wadcutter is a neat idea.
After some thought I don't know if there would be much point in leaving the check on the nose, except maybe to hard-nose a soft alloy.

[Larry Gibson]

I never found a need to leave the GC on the nose or the base for that matter. For me these WCs in rifles are useful for gallery, cat's sneeze and vermin reduction loads. At their low velocities they perform extremely well.

While I have scrounged Lyman slip on GCs in various calibers to use I have found my own home made GCs, especially the thinner ones made of pop or beer cans, work very well also.
