1x fired brass not feeding

[Jmort1754]

No, I did that two years ago

Went to FL dies recently. Thought the type s were a good mid line

If it seems like there's no bump whatsoever, I'd sand the shell holder down 0.001-0.002 at a time and check (less expensive than messing up a die).

Look at Cortina or SAC dies. Or grind the shell holder.

What’s the headspace measurement on new brass or factory ammo that chambers fine versus the once fired that’s too long?

JM1754, if I understand correctly something changed recently and before that change you had no issues. This seems to be the switch to a FL "type" die (whether type-S or otherwise). You've already determined that you aren't getting shoulder bump.

Lots of good input on this thread. You are correct to move to partial full length sizing (i.e. shoulder bump) as you can only neck size for "so long", however long that will be.

As you FL size you squeeze the case and the shoulder actually initially moves forward, until the die makes full contact with the shoulder and then starts moving the shoulder back. If you cannot screw the die into the press deep enough you will be unable to achieve this. So yes, the answer is either taking down the top of the shellholder or taking material off the bottom of the die. The last time I encountered this the latter was my solution as I needed to load on a progressive so taking down the shellholder was not an option. Pretty sure either of these, allowing for a 2 or 3 thou shoulder bump will fix you up.

New hornady die came in, bumped shoulder .002 and now it loads slicker than shit.

FYI I have had very good results with my Forester bushing dies in 6.5PRC, 7PRC & 300PRC. Only the 6.5PRC was chamber with a wide base reamer. I use this in combo with the Cortina mandrel die. So far no clickers in any of them.

Never knew shit fed that slick

Pleased you got squared away....

Hard to know without being there. Could be shoulder bump, could be case head, could be some other things.

I run a 7 SAUM, these stumpy mags have a tendency to swell down by the case head. Many FL sizing dies don't size down low enough to tighten that area to prevent against getting clickers or hard bolt close. I bought the Eric Cortina expander mandrel die. Not only only does the mandrel work very well. That die resizes the base of the case lower than the FL sizing die. For me it was just a few thou difference but it made the difference in my 7 SAUM.

Also for what it's worth. Hornady one shot has created problems for me. The RCBS case lube is miles better.

Gentlemen, I wouldn’t be surprised if none of you are watching this as it’s a couple weeks old and the issue was resolved. I just want to say thank you, and I really enjoy Rokslide. I’m new to reloading and got myself in a bit of a bind, but this thread resolved my issue quickly. For a newb, it’s great to have a resource and experience you can draw on. Thanks again hope you all have a wonderful week.
