If you're lucky, someone may be able to do chamber casts for you to reverse engineer it.

You'll have to tell us the intended use for them. Is it target or hunting?

The first thing I would do is get rid of the bevel base. It's good for easy loading but not for accuracy.

I can send you some .35 bullets from original molds, both the #1 conical and #2 cylindrical for you to measure. PM me with your address and I'll send a few samples.

Thanks so much Bruce;

Have an original single cavity mold in 38 cylindrical I might be willing to part with, dark patina and casts with a fin near the base.  Have not done anything to it except cast a few bullets and oiled it afterward.  jbkhays@centex.net

Frank,
They may be striving to re-create exact copies of the original Maynard bullet design....and every single Mass. Arms-made grooved bullet mould I've examined has that bevel base on it. I understand what you're saying , and I agree...but bullets made with those moulds seemed to work OK for Maynard shooters back in the day - if you examine the match scores.

I read a lot of stuff and can't remember where I read this......but I understand that Mass. Arms supplied their Maynard customers with a grooved bullet mould cut to be perfectly matched to each rifled barrel. I have noticed that Maynard rifles of the same caliber have some variation with respect to land and groove dimensions - likewise...moulds of the same caliber drop bullets with different dimensions. I really wish the heirs of old-time shooters had kept all the stuff together...!   

If they get this reproduction mould thing up and going, and if the dimensions are correct for my barrels, I may need to consider getting some for myself. The old Mass. Arms moulds are beautifully-crafted -- but are a real PITA to cast a substantial number of bullets with...     

My 40-40 has the original mold with it and bore of the rifle is huge compared to Froggies and mic's out at Ø.424". My mold throws a bullet of Ø.425" and Froggies original mold throws about Ø416".(if mwemoery serves me right) That is a huge variation and both are 1873 thick rim barrels. Later, moodyholler
