Been reloading for a 270 WSM for a little while now. Case stretch is pretty bad with the Hornady New Dimension dies I'm using. Also several stuck cases using these dies and one shot.
Anyway the stuck cases issue can be resolved, I'm looking at the Redding FL type S bushing die to limit case stretch and hopefully make a more accurate round.

Has anyone tried these dies with the WSM's or other cartridges? What do you think?

IMO there is no better factory FL die than the type S bushing die. Of course any fl die needs to be set up to work properly and not over work the cases.

The Redding dies are my go to dies in several calibers. I particularly like the bushing dies and would recomend a neck die and a body only die to give you the maximum amount of control over your reloads.

You may want to get a Custom Redding Full length type s bushing die. You send 3 fired cases to Redding and they match the die to your chamber/fired cases. Then you will have the best fit. Price on there website is $121.50. Special order. I use the bushing die in my 243win. works great.
