Anybody use one of these?
Do they really improve groupings?

You have to slide them slightly along barrel while checking groups. Yes they do improve groups slightly if you can stand to have to look at them on the barrel. They work best on thinner barrels.

Use the search function.

And no, they are made to separate you from your money.

They do work a bit-just not near like advertized. It's a moot point if ya reload anyway.

I have a 300 weatherby mag, it is well worth the 16.00 dollars.
I have a very good shot placement, the simms made it alot tighter.
all you gotta do is try it and you will see its worth it.
