Do people use .22LR rim thickness gauges?

[ovenpaa]

I was asked today if I could make some inserts for the Hornady type comparator to measure the rim thickness of .22LR ammunition, are such things still used these days, I thought .22LR was so consistent there was no need to measure the rim thickness...

There are such gadgets up for sale in the Sinclair reloading catalogue

The benchrest guys use gauges - I think we've an article on it in April's Target Shooter.

I will make a couple of spares then, they are simple enough to make and if I have the machine set up.......
