Seater plugs that 'fit'

Post by inthebeech on Mon Jun 30, 2014 6:05 am

My wadcutter pluc in my RCBS die set is leaving indentations at the front edge of my Speer HBWC.  I'd turn it perfectly flat on a lathe, if I had a that he that is. 
Is there a brand of die set that makes a flat ended seater plug?  
How are you guys seating your HBWC's?  I've heard of filling the recessed area at the end of the plug with wax or epoxy.  I'll screw that up. I'd prefer something precision machined and ready to go.

Steve Bathje makes wadcutter inserts for different dies and sells them on his ebay market.  I have one for my Dillon and it works great.  If you dont see it listed just send him a message.
Here is the link.

I assume you're talking about 148 hbwc
Are you sure you are flaring the case enough?  Mine set in quite a bit & are square to the case from the begining.

We're definitely going in straignt.  It is just that the small, raised edge on the plug, intended to do a rough job of orienting the semi-wadcutter, makes a small ring indentation on the outer edge/lip of the HBWC.  The indentation is pretty concentric for sure but if the bitter end of the plug were truly flat for its full diameter, then the center of the bullet which is at an equal height as the edge, would likely share the load as the bullet was seated and perhaps make next to nothing as far as deformation.  But if everyone is using the standard SWC plug then I'll go away and live with it.  It's likely not hurting accuracy.  I just thought I'd ask if I'm missing the "secret" to seating HBWC's.

grind it out with a dremel, no big deal since it seats off the edge not the nose. done mine years ago, works like a charm, I hated those little rings

I use Redding dies and they have a flat seating stem for 358 caliber WC . No cut out on stem just flat. When I bought the Redding dies it can with a RN seating stem, I called Redding and asked if they had one for a WC and they sent me this flat stem at N/C. I would give RCBS a call and see if they have a similar flat seating stem. They might even be like Redding and send it out at no expense to you.

For 148gn L-WCs and L-HBWCs, I find that a lot of flare is desirable so the bullet can be partially seated in the case before the seater plug contacts it.
I had Lee take their flat-faced seater plug and drill a cavity/hole in the center so the "button nose" wouldn't get smashed during seating.
SWC seaters are best if they only contact the bullet shoulder and not try to seat from the meplat. For a full wadcutter, there is nothing but the meplat to use for seating, so I have a seater plug that only contact the outer edge of the meplat.

For my BIG Remington 148's I had a 158 expander with a 162 flare made. Slides right in.

Redding just told me of the days when they would make flat plugs for customers but have gotten away from that now. They just suggested the same ideas mentioned here. I'll check out the link mentioned above. Meanwhile I did a respectable job of turning off the raised section of the SWC plug, on my drill press.

Did you possibly mean .358" expander with a .362" flare made?

If so, who made your expander for you?

Another way to fit the plug to the bullet is to "bed" it. I do it for rifle bullets, but haven't tried it for pistol, but should work.

Fill the plug with any bedding epoxy (I use JB Weld), put it back in the seater die,  and into the press. Use a loaded round (or dummy), and put lots of release agent on it (I use Johnson Wax). Run the ram up and let the weight of the handle keep the pressure on it overnight. Next day take apart, clean off the excess. The plug will fit the bullet exactly.

Wouldn't I have to mount my press upside down for this? lol!

you can use HOT MELT GLUE for this also. Then you don't have to mount your ress upside down.
