Hie thee to a LGS and get RCBS Case lube to start.
Next thing if that doesn't work, get rid of that SB die.
(You don't/never did need it)
I agree with MEHarvey, loose the SB dies. not needed if you have a in spec std die. My set is a Redding for my 458 SOCOM.
I also use a RCBS Rock Chunker for more pressing power.
Try anything else, if you are a Hornady guy try their Unique lube, it’s much more effective.
One shot works great on the vast majority of what I reload except 45-70 and 50 Beowulf.
I use this wax for everything! and it cleans up easy with rubbing alcohol
Old school, I don't think anybody marketed "resizing lubricant" when I started. What we did back in those days was use a very heavy oil, nay a light grease. Soak an ink pad with it, very lightly. Doesn't take much. Then we rolled the cases (usually 5 at a time) on the pad. The trick was a VERY LIGHT coating. Once resized the brass then had to be degreased. I use my vibratory tumbler with ground walnut shell for this.
So yeah, try a real lubricant. Oh and I'm using Hornady dies. Never had a problem but then I've only loaded about 500 rounds .458 in total.
I guess there is the aspect of using the same name for a number of products.
If the OP is using this.
It would be even worse than this.
As hard as that is to imagine.
NICE! are you going to use a Lee Crimp die?
I’m experimenting with .405g Hard Cast on my .458 SC. impressive numbers
getting 1725 fps
I know it works fine in most cases, none the less it fails to work so much more often than the alternatives that it's always the first thing to change when troubleshooting.
Here is the next issue. The Lyman seating die has a cup in the seating die similar to a round nose bullet. The issue is if the Hornady 300 gr. hollow point isn't almost perfect straight up and down, the seating die will shear the very edge of the lead hollow point. You have feel each bullet slide up into the cup or the bullet push in. The minute it feels like a hard stop, you have to back it back out. Try and realign the bullet. Then try it again. This may take 4 to 5 tries. Yes the case has a slight bell to he mouth from the charging station. Anyone else have this issue? Again is this a design issue with the seating die or just an issue reloading 458 Socoms?
Your having all kinda issue with Lyman. Have not had problems with my cheap Lee Set.
Mabey get a Lee set?
Are you using any thing to expand the case beside the expander that came with the sizing die? if not use your deburring tool and camfer the mouth of the case to break the sharp edge.
I've loaded the Hornady 300 gr HP without any problems. I use the normal seating stem that came with my Redding set.
Pull the seating stem out, chuck in in a drill,
and take some 220 wet/dry (oiled) sandpaper
to the inner contour/edge of the cup.
Round it out to a gradual transition
Thanks for the reply. It's funny. After I posted this request for help I took apart my lee 30-30 die set. Brand new it had a really sharp edge. I spun it in a drill and hit it with some 3m cloth. I then did the same for the Lyman. I can see why it was shearing the lead. Bottom line just breaking the sharp edge took care of the issue. I haven't sheared one off since. I still need to be really careful since there isn't a lot of room for error but I'm thinking this will give me better loads as well. Thanks again.
