I have two unopened boxes of Hornady 416 gas checks. One box bought in 2008 and the other in 2014. Part # 7125.
Looking to trade them for OLDER .22 Hornady gas checks. I’ve been told new Hornady’s do not work and I tried Gator’s and they do not work.
To buy 416’s today is an expensive proposition. So I need at least two boxes of the .22’s.
Thanks!

I have tested both the old Hornady and the gator and have seen no big difference in accuracy. The gators are a little thicker and required sizing nose first in the Lee sizer. I also made a flaring tool to square and open the gator a little more for easy slip on fit.

I should have explained better.
I've not been able to do any load testing yet, so accuracy is not yet an issue. My challenge with the Gator's is getting them on to the bullet. They crimp on OK but the force requirered to do that causes the bullet to deform, forming a "plowed ridge" on the bullet's nose, about 3/4 of the perimeter of the nose, 1/2 way up. Not a problem but the base of the Gator, after sizing, is rounded, not as flat as the base of a Hornady.
The Gators are about 0.234" dia. The Hornady s are about 0.228" dia. The sizer/lubricator is a Saeco. Maybe my CB sizing dia. @ 0.224" is too small, maybe I should use a 0.225" instead?

Sounds like you are using soft alloy. I always used the .225 Lee sizer (nose first) to prevent deforming bullet.

The alloy reads 10-11 bhn on my LBT hardness tester and maybe that’s a part of the problem.
The pot is a 40-pounder made by Magma and it’s about 80% full, so emptying it and starting a new batch will be a bit of a project. I have no lino to add to it but lots of tin.

Tom I wonder if you could find a nose punch that fit in side your gator check close to it’s side walls and size them before they go on the bullet. The bullet stop could be raised to bottom out before setting the crimp?

Dskid,
Thanks for the suggestion!
I do have quite a few top punches, so I did some research. I can see how, if you had just the right one, this might be a potential solution. But I wasn’t lucky. What I have are either too small or slightly too large.
A friend has some of the newer Hornady’s and he sent me a handful. They seem to work OK so for now I have solved the problem. Looks like alloy and gas check shaft diameter variances on the base of the bullet, can influence our impressions of the suitability of the newer Hornady gas checks compared to the older version.
