Great write up, know my next mold "fixing project! For sure a sticky, I've already saved this and will go over it a few times before I proceed. Fine job sir, fine job.
Undoubtably the best post I've ever read on lapping a mold. Crystal clear instructions and photos. Remarkable. And please do a post on lapping that pistol barrel!!!! I have an old 3 screw Ruger .357 that has the same problem and really need to see that write-up. Thank you Sir! Audie...the Oldfart..
Today was a shooting day for me so this morning I hadn't read the entire post but sure glad I got back to it this evening.
Gear is half right, this is not only sticky material in the molds forum but also straight to the "frequently asked questions" forum also.
Exceptional write up, impressive to say the least.

Thank you all for the great comments. It makes it all worthwhile to know that you appreciate my effort, as do I when I read the many other useful and interesting threads on the forum.
I will try and do justice to this when I get around to doing the bore lapping thread ...:)
I put up a suggestion to add this and another pertinent link to the "Beagling" FAQ thread that's already in place.

Sticky for sure!
Great job. Thank you for taking the time to post this.
Thanks for this amazing tutorial
Quite enjoyed the read.
Better than the lap a bit and test method I have painfully used before.
good work
Love the mic
Great tutorial and great pictures. Thanks for taking all the effort in making it so easy to follow!
I just seen this thread for the first time...WOW !
Stickied !
How did I miss this until today? Well Done, Sir! Well Done!
( Is "Jolly Good Show" the correct response?)
Yes...I vote STICKY.
Please post when you find a way to lap bores this easy and accurately.

I am curious about this, as I have the exact same mold and WOULD want to take all the bands up to .359"-.360", and have the same issue of the front one being smaller than the back two. I'm guessing that you'd start by doing all three bands at once, until the larger back two reach the desired spec, then cast some new slugs and only do the smaller front band? I'd think you'd need to leave at least the rearmost band on the lap to ensure everything stays straight?
Well the directions work just great! I fixed my Lyman mold H&G clone for 45ACP 200 gr SWC. Was 0.4505 and now is 0.4525. Perfect for my old faith ful. I can size it down one more thousand if my Gold Cup likes that better.
Thank you!

Before reading this post I lapped an undersized .401 Lyman mould a few days ago. I did it basically the same way, with excellent results. Very nice write-up.
Thanks for this!!! I'll be in the shop enlarging my RCBS 416-350 tomorrow. It drops just a bit too small and a 416 sizing die barely touches the parting line even when cast with pure Lino. I bet I need to cut the GC shank down to keep from enlarging this area.
ETA: Followed the instructions and it works well. I now have a fatter bullet that actually gets sized by the sizer instead of just barely getting touched. Took less time than I thought it would and the bullets drop out nice and round and literally fall out of the mold. THANKS!!!
