Title: Slug the barrel
Post by: DJK11 on January 30, 2021, 11:36:57 AM

Question for the experts:  So can one slug the barrel with a coated lead bullet and obtain acceptable results?

In my mind the coating has nothing to do with it.

You need a chunk of soft lead, maybe 0.004" larger than your bore, some good oil, a strong rod to push and hammer with, and a good micrometer (or excellent caliper).

I typically slug 9mm bores with 38 bullets that are the appropriate oversize, but not sure where to start for 45 cal. I've seen fishing weights discussed, but have no idea what sizes they come in.

Thank you.  I’ll give it a go and see what happens.  I will use my press and hardwood dowel.

For 45 ACP you can use .458 black powder slugs.

Never had an issue slugging a bore whether it be a 9mm or .45 with a freshly cast bullet. I have bought .451 and .452 lube/size dies as I have run across larger bores before on some 1911's.

Do you inspect for stirations along groove bearing surface or assume it worked. Personally, I don't use oil as that might affect reading and never had any leading.

Beartooth bullets used to sell lead slugging bullets for just about every caliber. They also had instructions with them.

I've taken fishing weights/ wheel weights and melted them down in a fired case (in the caliber your slugging).  It makes a slug just oversized and has a slight taper to ease starting it down the bore.

I just sacrifice a case and heat it with a torch and add lead until full. Then let cool and use a kinetic hammer to pull the slug out of the case.

Cheers,
Toby

That's the exact method I use.  I use split shot lead that I previously cast from soft lead.
