Veral,
First, I love my 45 WFN mold, I have wanted one of these for years, after my first casting session all I can say is god bless you!

Second, I have put 168 lapping loads through my 45 SS blackhawk consisting of clover brand 320 silicon carbide rolled onto air cooled WW.

I was looking back through your book and didn't see where you talked about grit size, maybe that was with the kit. Seems like years ago your kit had two grits.

There is not much sign of the constriction coming out. Would you recommend dropping down to 280 grit or keeping this up? According to teh lead push through slugs end is 452 and all the way through is 451 same as when I started.

I'd reccomend that you get my lap kit, which cuts faster than clover compound. I make it up and use a very high grit concentration because it is needed to cut down on the lap time. Had I found clover lap compound to work well I would have never developed my compound. Definately don't go coarser unless you want to rip out a lot of throat. The problem with using clover or other parts house lap compounds is their slow cutting action which wears throats excessively, far more then the LBT lap kit compound. It is well worth the small price.

Well, I guess I'll order it. I had your kit from several years ago, a buddy and I split it, seems like there was two cans or grits then. Anyway that stuff was lost a move or two ago. I can't remember how many shots it took then on a old security six we did, but it had been shot pretty hard before lapping.

How many more do you think it will take to remove a half a thousanth or so? Boy that stainless is tough stuff. I'm tired of wasting primers.

15 shots if it were a S&W, but the stainless that Ruger uses is far more abrasion resistent. Probably 30+. Be sure your lap bullets are around 12 bhn hardness, which is air cooled wheel weight metal aged at least two weeks. To soft doesn't cut fast, too hard doesn't cut straight.

I used the lap kit today I recieved from you. Twenty shots, and the cleaning patch squeeked to within a few inches of the muzzle when I was cleaning. Used to only squeak for about eight inches. I'll put another five through it tomorrow, and do the final patch lapping you recommend afterwards. Sure seems like it is doing the trick! Thanks for a good product.

Thank you. I've learned to expect your kind of answers after several thousand lap kits sold!
