I use mostly Lee dies, I like those collet dies too. I bought some Herter's dies used from an auction site in .223 recently,I couldn't find them in stock any of the usual places. Ebay had them for a ridiculous price, I saw some go for more than $90 for Lee's. I got the Herter's for about $15, I haven't tried them yet, they might be junk. Have you ever used that brand?
Yep followed your link and that's them. "Compare Lyman "All American" dies from the 50's and 60's and they look just like Herters, even the lettering font." I've not been reloading long enough to remember lyman dies from the 50 & 60's though but that at least sounds like they may not be total junk. I don't remember the .223 being that popular in the early 70's. I had a .222 back then I thought it was a super gun. LOL Other than military though I never seen a .223 around. Remember back in 1972 a box of Remington or Winchester .222's only cost $3.98. Heck who needed to reload stuff with them prices?
