With Dan at Mountain Molds retired, I am working with Lee to get his bullet designs redrawn and submitted to Tom at Accurate Molds to add to his catalog so they can be cut. This thread is going to be where the drawings are posted and they will be labeled with the Accurate Molds catalog # so you can easily order a mold. I will get as many/all of Lee's designs done as soon as possible. The first design is Lee's 41-240gr LFN  The next design is the 45-315gr LFN. |

Thanks so much to you for going to the trouble to do this and to Lee for being willing to share.
Ive got the specs for most but it took a lot of time and I’m not sure I have it all to send Tom.
Was lucky enough to have a fellow Forum member order me the two .41 designs from MM before they closed.
Have cast some of the smaller one (240gn) and they look really good.
Cant wait for the .45!

I believe Tom uses a 60 degree included angle on lube grooves and crimp grooves with a flat as part of the crimp groove. These are items that are a deal killer for me. You need to go look............................

You need to go look............................ hey boolitdesigner, newbie question(s) here, what are the merits of 50 degree inc. angle vs a 60degree? assuming ease of release from the mold? also regarding crimp grooves, what are the advantages of no flats vs flats? Don’t think i’ve cast or loaded bullets with flats many thanks, Chris |

Don’t think i’ve cast or loaded bullets with flats many thanks, Chris Hard to comment on those things I've never used. My methods are completely different. I do suspect the angles he uses are for ease of manufacture though. |

I have a few of Accurate Mold molds. I haven't seen anything wrong with them and he is very accommodating.
Flats, no flats 50 degree, 45 degree, 60 degrees or any other type of degree's.

You need to go look............................ I am sure Tom can cut whatever we want. Not having as cast actual bullets to measure from a mountain molds mold I am kind of winging it. But will gladly make changes as long as Lee is good with it. So I have to ask, why the included 60* angles for the crimp and lube grooves are a deal killer? As has been mentioned I think Tom does it for ease of releasing out of the mold? Is there any structural or design reason aginst doing it? Does it cause any accuracy issues? |

Is there any structural or design reason aginst doing it? Does it cause any accuracy issues? First off, I want to thank 41freak for doing this. When I designed these bullets, I never imagined there would be interest in the molds. As for 60 degree angles, there's no flaw to be found. And it doesn't impact accuracy at all. If someone thinks otherwise, show me the science. Or better yet, show me actual targets. All of my LFNs have been shot heavily at 100 yards. If the gun and shooter are up to the task, they perform exceptionally well. Another thing to add. A good friend of mine competes in benchrest cast bullet competition. A lot of them use molds with various lead angles, to include 60. Declarative statements minus support don't go far with me. -Lee www.singleactions.com"Chasing perfection five shots at a time" |

Ya know, all I said was " You need to go look............................". If you're happy with what you created, then shoot it to your capacity. As far as it doesn't effect accuracy, you would be somewhat inaccurate on that IMO. As far as CBA competition, BTDT and am past what they do. I merely tried to list some of the items that may change your design from what you conceived. Good Luck with going to a different maker as they all don't do the same thing.

"You need to go look....." tells us nothing. If you have wisdom on the subject, share it. Explain to us the 'what' and 'why'. Otherwise it's conjecture. -Lee www.singleactions.com"Chasing perfection five shots at a time" |

One negative is the turnaround time is now 10 weeks. I hope he can maybe get some help. I like Accurate Mold molds.

Otherwise it's conjecture. -Lee www.singleactions.com"Chasing perfection five shots at a time" "You need to go look" refers to what specs Tom is using. Not my specs...His specs. What and Why... I'll refer to Elmer Keith in his statement Lyman ruined his bullet when they changed from a squarish lube groove to a round one. He didn't explain that statement that I know of, but a year modifying the round groove Lyman bullet on my lathe to his square groove with the correct groove shank diameter and the draft angle on that lube groove showed he was correct. There are things you just have to see for yourself as no amount of explanation will get through to people on controversial items. This is something that would take an entire series of posts and would result in a lot of heat generated. BTDT and it really induces heartburn....................... |

Has anyone ever made a Keith bullet with a square lube groove and an identical bullet with a round corner lube groove and tested it in a known accurate handgun and see if there is a real or imagined accuracy difference?
Not just shooting a couple 5 shot groups but several to confirm the findings.
