Smushing lead HP's

[tomh1426]

Ok I got the round seating plug from RCBS today and tried reloading some nosler 158gr HP's.
It worked alot better than the SWC plug but it still changed the shape of the lead tip.
It starts off as a cone shape and when I seat it it ends up a bowl shape.
Its hard to get it to seat exactly the same every time.
So what am I doing wrong now??

BTW. RCBS has VERY good customer service, they sent me all new plugs and lock rings and would not take $ for them.

No one else has this problem?

Might add a tad more bell.

 

[tomh1426]

Ill try that, I have it set like the manual says " Case mouth should be belled just enough to accept bullet when place on top of the case-no more!"
I have some empty brass, Ill try it later today.
Thanks, Tom

still rounds them, i guess im gunna shootem and see how they work
the smush dosent bother me as much as diff seating depth

One option then would be to send a seat plug and a bullet to RCBS and let then build a custom seat plug. I get minor lead deformation using bulk Remington 38 bullets but the ones you are using did not deform so much for me.

Well after I use these up I think Im just gunna try a diff bullet.
I wasent having any problems at all with the Nosler silhouette's besides finding them locally.
I tried plated bullets and they are ok
I should seat and pull one and send it to RCBS along with a untouched one and see what they do.
I think Its asking alot but wth

Working over a seat plug for a particular bullet is a service RCBS has provided for a long time.

 

[tomh1426]

Really
Its amazing how far they go to make us happy
Ill callem tomarrow.
Hope I dont have this same problem loading cast .45C
Thanks Tim R I knew someone had the answer

 

[tomh1426]

I just called them, they asked for 3 sample bullets and $19.95
If I knew that I was gunna shoot alot of these I would do it but I just started reloading and would like to try diff bullets.
Its nice to know I can have it done but for now Ill wait.
I bet I could turn my own
thanks, Tom

I wonder if a cone shaped cavity in the seating plug would work better ?
You could try seating and crimping as two separate steps.

 

[tomh1426]

Get another die just for crimping or adjust my die and make it a two step process?

It would be worth trying and if it helps look for a used set of dies I've seen RCBS .38 die sets for $5 at gun shows. When I seat hollow points I do it slowly this seems to help. The RCBS sizing die may size more than it needs to, but this does seem to work well with plated bullets.

I had that problem for awhile, and 2 things I did were to bell the case mouth more, and seat and crimp in 2 seperate steps. The pressure required on the nose of the bullet when you crimp is what is deforming the nose. Since I did these 2 things everything has been fine. CB.

ill give it a try, right now I gotta shoot some so I can loadem again.
