A GOOD REVIEW FOR NEW HAND LOADERS

[Bill Norris]

The bulletin has this dated Sinclair article in it today concerning setting up the F/L sizing die. It is a good read for new hand loaders and maybe a re-read for all.

Good timing as some have had sizing issues, it seems lately. So would be very good for them to read this bulletin post.

One thing to add to that article. Just before the shoulder bumps, you may see hs measurement get longer. If this happens you will know you are very close. This happens because the case is being squeezed and pushed the shoulder forward slightly. Continue to turn in the die in very small amounts until you get the bump you want

Absolutely.

Yep, it sure does. It freaks a lot of people out before they understand the cause of it.
I try to explain it referencing squeezing a balloon. They see how the balloon will lengthen. Then I place my other hand over the top of the balloon and squeeze again. They see the balloon cannot go forward and can relate that to pushing back the sholder.

An informative video. Takes the mystery out of the process.

I have one question. Unless Sinclair changed the design of their bump gauges, they index off the shoulder not a datum line on the shoulder. They claim it is a more precise method. Whereas Hornaday and Whidden bump gauges index off a datum line on the shoulder.

Any thoughts on that?

I don't think it really makes a difference, just a reference number to track amount of bump you're inducing.
