Just curious if anyone has had success using these or are they a waste of money? I am starting to reload for my tikka in 308 and I would like an easy repeatable way to resize brass. Any input would be greatly appreciated.
They would be better if they were in 0.001" increments. I do not understand why they are not.
Your brass spring back varies with the brand of brass and how many times the case is reloaded. Meaning the .002 increments between the five shell holders is good enough.
Pausing at the top of the ram stroke for 4 to 5 seconds will make the shoulder location more uniform with far less brass spring back.
An option is Whidden's click-adjustable lock rings which have been evaluated locally with positive results:
With our Universal Click Adjustable Lock Ring (Patent No: 10,393,488) you can instantly turn your sizer die into a Click Adjustable Die. Our ring works with any 7/8 OD sizer of any brand with adjustable shoulder bump. Simple in design the inner and outer ring can rotate independently of each other. Each click is metered in true 1 thousandths adjustment and has .100’’ total available travel. Those loading for two rifles with different headspace can easily optimize the shoulder bump for each rifle.
We have also been asked if this lock ring will work with a seating die. All Whidden Gunworks Seater dies are Micrometer Adjustable however other Seaters that are not micrometer adjustable will benefit from this lock rings adjustable design. Even the simplest seater dies are now easy to adjust for different bullets or easily adjusted for testing different seating depths.
The trouble with shims is you are working with an air-space and are at the mercy of press flex and linkage slop. The Comp shellholders pre-load everything and eliminate that variable.
