    Thanks for the replies.

    35remington, I know that less sizing will result in longer case life, all else being equal. I think I have a tight chamber and gun, and that will certainly produce different results than someone with a loose chamber and using minimum dies.

    I've been thinking on how I can measure the shoulder. Im going to try using a socket to index on the shoulder and see if I can get a repeatable measurement. If it works it won't be as good as a store bought comparator but it will offer a close idea .

    Trapper, I know lube dents result from too much lube on the shoulder or right below it. I get small dents with Hornady one shot. I mention it as evidence that my dies are indeed moving the shoulder some.

    Drop a .357 mag case over the neck of the 30-30 case and measure the oal before and after sizing. Then store 357 case in your die box to use for future measurements. A 38 sp. case will also work, heck maybe even a 9mm case.

    Thanks longpoint, it didn't occur to me to use an empty casing. I'll try that and see if it's consistent.

    I was not sure you know about the over lube. I use Hornady Unique for my case lube .

    Thanks trapper,

    I've not tried the unique lube yet. I've been using imperial or Hornady one shot. The one shot though, because you spray it one gets on the shoulder. I don't scrimp on it, and it'll make little dents. It's a lot faster than the imperial, but I like the imperial better.
