I believe the word is meplat. I don’t shoot over 200 meters so can’t answer your question. Wikipedia does have a small technical article on how a meplat effects down range performance.

5 minutes more elevation for a potentially better balanced bullet seems like a fair trade-off. Now it's time for me to get the lead pot out and cast up some for practical experiments. Thanks all. Now I feel better about buying the used moulds

I have read many times about cast bullets and trapped air pockets. It's a given with poured lead. Swaging is the only way to eliminate. Pope did his nose pour moulds to place trapped air in nose rather than base to have a better balanced bullet. Granted, he only shot at 200 yards so I was concerned about longer range. After Hoch closed most nose pour moulds companies are gone. I believe Brooks will still make custom nose pour but don't know of any others. The Hoch moulds I bought were reasonable in cost  enough to give a trial. I see everyone seems to be jumping on Money bullet profile so this will be something different for me to play with. I enjoy doing things against the grain so to speak.

Didn't Mann do some horrible things to bullet noses without making significant changes to the results?

I still use a flat nose bullet in my 45s. The Saeco 530 gr bullet. Me and Chuck tried the long elliptical money and postel style bullets way back in the 80-90s but just could not get them to shoot accurate. 
I get admonished for using the Saeco occasionally so I tell people the flat nose squares the bullet up against the air to keep the bullet stable. I also add that the round nosed bullets dip and dart around when they get down to the speed of sound. Seldom do I shoot past 500 meters.  

I don't like a long unsupported nose on any lead bullet.  I have a couple spitzer bullets that shoot very well in my 45s.  At 1000 yards the Lyman spitzer is over the top of the target with a Saeco 530 sight setting. 

The Mathews tapered spitzer shoots extremely well in one of my 45s. Trouble with it is, it has to much taper so that only about half the bullet is supported in the bore.

You can get excellent bullets from a good base pour mold.  Nearly everyone I've shot with use some form of Buffalo Arms money bullet although there are a few exception.  They can be incredibly accurate at long range.

One interesting thing that a lot of long range shooters ( at least on the internet ) haven't paid attention to is that Dave Gullo, arguably the best LR black powder shooter, sells the molds he uses.  His catalog even shows pictures of targets he's shot in testing.   This is a very good guide for selecting a good LR bullet. 

Like Don said, those Saeco bullets with the meplat do shoot well.  I have only used them at Silhouette and can say they need more elevation than a comparably weighted "Money Bullet" but are deadly accurate.  More elevation means lower BC which means more sensitivity to variable winds, depending on a few other variables of course.   

The variation of elevation with changing winds is a big factor in shooting a good score.  Even in midrange at only 600 yards.

I do have more than my share of 45 cal  greaser moulds including a first pre production BACO  Creedmoor, an original pre1950 Lyman Postal, a Paul Jones  Creedmoor and several others I have played with in the. past. I thought it would be interesting to jump into the diaper wrapped slugs. Should be a whole new set of challenges to deal with. It is for a new to me   Shiloh #1 recently acquired. Moved to Tucson area and am starting over.
