Ok fellas one more thing i need to know and i will have all this mastered!! LOL!! I have both a redding type s and a so called fitted Harrels 30BR die #2, The redding die sizes my brass about .001 at the body/shoulder taper and my harrels die doesnt seem to be sizing this area much at all if any. However when i use the Harrels die i have zero problems chambering the round. it goes right on it just like it should. I do have an issue as to were the brass will not fit up inside the wilson seat die, while using the harrels though. Thats an easy fix though. My question is, do i use the harrels that seems to be working fine, but isnt sizing the brass much, or do i use the redding that sizes the brass the otherwise proper suggested size for fl sizing. I was always under the impression that a proper FL size die would re-size the brass about .001 at the body shoulder taper area, and in this case the redding does, but the Harrels does not. I cant seem to tell any difference on the paper, but testing has been somewhat limited due to weather. What do you fellas think? Thanks man!! Lee

In most cases, the "factory", (read Redding/RCBS) dies do not get teh web area of the case sized correctly. Your description of what is happenning also suggests that. The Harrel's dies are really good at getting that job done. As long as it is working, find someone who needs a 30 BR die and unload the Redding and get your seating die opened up. It may only need .0005 or less as what you call sticking may well just be suction. Try pulling the stem up and see if the case will fall out that way. A damn small differential in size can cause a tight fit in a tapered situation. If it won't fall out, just a bit of judisious polishing may do the job as well. You may not have to ever put a cutting tool in the die to make it work. Don't lose sight of the fact that there is not a single item we are dealing with here that has a SAAMI spec associated with it. This is ALL CUSTOM, and you need to be ready to ADAPT!

Its not suction i have to pry the case out of the seat die. the seat die is just a bit to tight. Easy fix though. We talk about self centering at times, and i just wondered if that had anything to do with this situation. The redding is sizing the brass .001 smaller than the harrels. is that really a bad thing? Thats my question. the groups sure dont look like its a bad thing, but like i said, its a bit early to tell the hole story on this new barrel. Lee

Either of your Dies are working fine. The Harrels is working a little better (closer fit). I would love to have the Harrels die if I knew my chamber was the same as yours. But I would also be fine with the Redding. Fix the seater die or better yet send me the Harrels die!!!!!!!!

Glenn, you know perfectely will you have all the equipment to make whatever you need. Shame on you.

Lee, when the weather warms up you may find the cases need a bit more sizing. Having an extra die that sizes a bit differently is never a bad thing. Most sizing issues I've seen with BR chambers have been at the front...depends on the reamer used, etc, etc.

A standard Wilson die has about .005-.006 clearance around the neck area. This can be a cause for hard to find runout. You can address this problem and ensure a good case fit by having the die shortened and the chamber reamer run in. If you're okay with the runout numbers you're getting now, you could simply polish the inside of the die. A bore mop loaded with valve grinding compound and spun with a drill works well for this. You can follow that up with some JB on the mop if you'd like.

Just my view from the cheap seats. :) -Al

You hit the nail on the head. Tomorrow or Friday I will be making me a FL sizing die with neck bushing for a 30 BR.
