What is the difference between the Hornady & Lyman Gas Checks?

[Dthunter]

Are either gas check better for a particular application?

Do one brand have a smaller internal dia/ cup thickness?

[Hickory]

I don't think one is "better" than the other.
The Hornady will crimp onto the base of the boolit,
where the Lyman doesn't.
I have noticed with recovered boolits that sometimes
the Lyman gas check may come off, where the Hornady usually will not.

I believe that the Lyman gas check doesn't come off until after impact.

I think you will find that the "new" Lyman gas checks are Hornady gas checks in a Lyman box, exactly the same gas check.

[Reload3006]

I have found them to be pretty much the same except Lyman is ten dollars a box more

[Dthunter]

Thanks guys! Thats kind of what I thought.

Lymans gaschecks are significantly more expensive!
really adds to the cost of the bullet.

[Le Loup Solitaire]

As already indicated they are the same product in different boxes, but the price.... Lyman puts their "cut" on the top so that they are more expensive than the Hornadys. Its a rip off either way; everyone should just make their own for a lot less $$$. LLS

[Dthunter]

What kind of equipment would you guys use to make your own gaschecks?
What kind/thickness of materials would you use?

[.30/30 Guy]

I use some of PatMarlins Checkmakers for my checks. I am very satisfied with the checks that I get using his dies.

I have been using Ace Hardware aluminum flashing for checks. I use 0.014" for GC checks and 0.085" for PB checks.

The thickness needed is dictated by the gas check shank diameter and the sizing diameter.

[DLCTEX]

The older Lyman checks did not crimp on like the Hornadys. Any manufactured in the past few years are made by Hornady. Gator checks crimp on and are cheaper.

One starts with an H,
And the other starts with an L...
(Well, you opened the door for that...)[smilie=1:

My Hornady commercial checks measured .017 thick in the cup bottom, copper.
The ones I make are .014 thick, and aluminium.
And I never could see a reason to pay $10 more to measure L brand.

But I have made mine from .006 copper, .011 brass, .0092 aluminium, and even .016 aluminium.
The Hornady, .011 brass, .014 Al, and .016 Al, all worked well for me. The thinner aluminium and copper, eh, not so much.

The targets and steels I shoot don't seem to mind either way. 8-)
