I understand what DW is asking for, the one bullet mould that will provide the best performance and at the same time will also be very user friendly. I just don't think he will find it based on a long pointed bullet with an exceptionaly high BC and with a length that puts it at the ragged edge of stability. I was just going through my tests after narrowing it down to 2 out 6 bullets for group shooting. One a Jones spitzer and the other a flat nose, both weigh the same 195grs. and light by most people's standards as well as short. The other bullets were more typical of what is currently being used with extremely high BC's thus more weight and longer length. They were dropped early on due to a lack of consistency. Between the last two standing the Jones and the flat nose both cylindrical bullets 260 5 shot groups split evenly were shot and the flat nose proved to be the more consistent and user freindly, as it does not require small variations in the powder charge with the change in density altitude as does the Jones. I am not telling DW by no means what he should or shouldn't buy, that choice is his and his alone. I am just trying to point out based on my exsperiance and supporting test data that what is working for me might be something he might like to take into consideration in his search for that one bullet mould that might work? If it were me in that search, this is something I would like to hear about as you won't see the use and benefits of a short cylindracal flat nosed bullet being recommended all to often. I should also mention for comparison sake that my 5-5 shot 100yd. groups are now averaging 1/2 inch and under if I don't decide to wing one out there by either stupidity or a bad condition call from time to time.

thank you Ken I really appreciate you checking that for me.       That moves the discussion a step farther ahead

so now we know the groove diameter and the twist of that specific rifle. Matching bullet diameter to bore is not hard. But, assuming a bore-riding-nosed tapered projectile; what length/weight (in Woodie alloy)will stabilize at reasonable 4759 non-leading velocity loads

John,   you say "flat nosed"---I have a mental image of an old fashioned wad-cutter, or the old long-discontinued Lee-modern-minie bullet 
(which by the way shoots really well in my original percussion w/loads of 3F---and it makes such nice clean holes in the paper-none of them raggedy hard to see and score holes  ) 
Or are you talking about a rounded bore riding nose with a flat meplat Like AccurateMolds offers?

Kind of  like the truncated cone flat nose on a keith style pistol wadcutter, not bore riding, then,   correct?

Hi John,

Is it like or close to this?

Accurate Molds has  a tapered style one in his catalogue.  I've used them for a couple other custom molds with great satisfaction of quality and service. It's # 32-195D mentioned above.  it might be made might to work.  Tom allows to you to adjust the dimensions a little. I've written to him about it.  I think the base and last couple bands might need to be a mite fatter for my groove diameter---not sure yet about the bore--really need to make and measure a chamber throat cast before I go any farther.  And maybe the nose needs be given a bit of a bore riding segment with a tapered cone to the meplat.  I'm concerned also about the overall length and weight/twist ratios.

bumming bullets is also a possibility
