I might be interested, however, I just purchsed the Saeco 300 gr tapered mold, dont know if I want or need another at this point. What would the base diameter be? Joe S

Joe and 1878:  You are asking questions that cannot be answered presently unless I had an original Ideal 375166 and had cast with it at various alloys.

You see, this mold has not see the light of day since the early 1970's and prior.

The group buy is to obtain 25 persons or more that want to buy the mold.  Then Lou Sellman, a Lyman mold distributor will put up $600.  Then Lyman will pull the 375166 original cherry off the shelf and cut the number of molds requested.

You know 1878 - I too would like to see Lyman's dimensioned drawings for the mold but. in fact I have never seen a dimensioned drawing for any of the molds that they currently produce.

Don Miller did not shoot any of the 24 black powder bullets that he did the revised Greenhill forumula in his article.  For the 375166, the dimensions in the article were:
Diameter - 377
Weight - 330gr
Length - 1.165
Length in calibers - 3.090
Estimated fps - 1300 

I have an original Ideal 37583 (145gr) mold that casts a 380 bullet using 1:16 alloy

singleshot1 ... Like I said previously I don't have this information because the mold has not been cut for close to 40 years.

The mold will be cut with the original cherry or from the original dimensions that Lyman has.  See the only dimensions that I posted previously.  If you know anyone that has the original mold and has cast from it that was sold by Ideal PRIOR to the early '70's ... give them a shout.  I'd be interested too.  Otherwise, look at the picture of the original bullet ...

Please remember this:
This mold will never be a production run from Lyman.  Lou Sellman, a Lyman mold distributor, will pay for and own the cherry and he will be the only source for the mold ... if this group buy ever gets off the ground

If it's any consolation, a group of us through Lou Sellman, purchased the cherry for the out of production Ideal 457192 mold.  I and one other person had samples of the original bullet and the special run mold was dead nuts on the original

If you or anyone else wants the 457192, they were all sold but Lou is ordering more ... (he also owns the cherry for this mold).  Send me a PM or mail and I'll give you the ordering details

And I might add, don't let anyone tell you a 330 -335gr bullet will not shoot from your 38-55.  Here's a couple  of 2006 pictures that I have not fine tuned the recipe for:

100yd target

200yd target ... the 8 ring groups were sight adjustments and both targets were shot with the H&R Target Model rifle

Update:  The holes marked D in the 10 ring are the final elevation and windage adjustments

$1600 for the Cherry(s) to make a short-run of molds? PLUS $50-60 for each mold?

For that, you could just order 40 custom molds from (insert your favorite custom mold-maker), AND you could be  sure of the dimensions, too.

Who does Lyman think they are? RCBS?

Westerner - Small correction.  The targets I posted were not shot using the Ideal 375166 ... The bullet was the Lyman 378674 using the H&R 38-55 Target barrel back in 2006l!  You know, the El Cheapo $400 rifle

This October at Ridgway with a revised recipe and a Uberti HiWall ... settings were otained on the vernier (200-500m) and the Rams dropped consistently with this bullet and the revised recipe

If a 378674 bullet will shoot to 500 meters and the Ideal 375166 calculates to 17.65 in a 1:18 twist barrel ... I definately expect better accuracy using this old Ideal re-make mold

Marlinguy, proof is on the paper and for a 1:16 twist, sounds like the Ideal 3765 272 is a very good bullet.  How does it shoot at longer distances?  Using original powder, do you know the twist ratio for this bullet in a 1:16 barrel?

Joe - I'll let you read about twist ratio and what is does.  Here's plenty of links using 'ballistic twist ratio' on Google ... (You need to Login or Register to view media files and links);
