A-1 die set. I especially like the sizing die. In one shot put in a 223 case and out comes a 25 caliber case. Be aware of too much crimp bulging the case at the shoulder.

Top quality.

haven't used them a whole lot yet, but so far 100% first time through perfect.

Bought these dies to start rolling my own .25-45 sharps rounds. Dies are what I expected since I already own 8 or 10 sets of rcbs, 8 or 10 lees, 5 or 6 hornady, and 4 or 5 sets of redding dies. The require the same intial cleaning, set them up and roll on. I am planning to order a custom lee factory crimp die, since one isn't available commercially, instead of using the seater die to roll crimp them.
When you size the once fired 5.56 brass, the mouth is noticeably bigger than a 5.56, then when you run them through the expander it gives them a final sizing to .257 pretty effortlessly. First batch I did with H335. Then add your favorite topping (bullet) and enjoy. I have high hopes for my new quarter bore. Fast shipping from SRC, and the only place I have seen these dies. So whats not to like?

RCBS always a top notch product. Expect no less from them.
