Here is my take FWIW, on the minimum velocity deal.  When some ranges started putting in minimum velocity/weight requirements, it was for a different reason than angle of descent.  It was so the bullet had enough energy to penetrate the 2X4 uprights.   When BPTR 1st got started, somebody was shooting a pipsqueak load and hit the upright. Instead of going through, the bullet ricocheted  down and hit the target puller in his foot. A lot of shooters missed this part of the reason for the rule and thought it was just because of the rapid drop of the bullet. This was banged around on the internet forums for a long time.
Now on the other hand, my 1st LR matches were at Harris, MN and those butts were definitely not safe for BPTR and now a new back wall has been built.
No doubt, safety of all kinds is needed to keep this sport going and any type of accident would be a terrible blow.  NRA scoring methods have slowly evolved to where the scorers hand does not go above the mid-point of the target when it's been pulled down.  Bob

Quantico has no guidelines, nor does the NRA. However, Reade Range does.

Normally 30min for sighters & 10-shots for record. Sighters are often unlimited at 1000yd (matches are 800/900/1000yd), but still only 30min. May vary a bit from range to range. If you can breech-seat and get off your shots in 30min, power to you.

Here are the NRA BPTR rules (mid & long-range) for those who might be interested.

I have not been on this site for some time, just a lot going on in my life.

I have shot my bone stock Browning 45-70 as far as the 1540 yard Billy Dixon target with good results.

I shoot a 535 gr. 16:1 BACO paper patched money bullet with 80 grs. Swiss 1.5, seated about .10", MV about 1370 fps.

BTW, we found a bullet in the sand from one of my misses, and it was hardly deformed, but nicely engraved.

I'm not a die hard minimalist, but I am confident in my Browning and not looking for something better.  It just plain works for me.

My theory going into this was that the lack of a leade in the Browning chamber would work well with a paper patched bore rider, and it looks like I was right.

'Money' bullets are characterized by their long, secant (IIRC) curve nose design, with is much more like modern high power target/long-range ammo then the traditional Postel or Creedmoor nose designs of yore. Their primary advantage is their considerably higher BC, so they cheat the wind better, especially at longer distances. Buffalo Arms has any number listed in 38, 40 & 45cal (and others) as does Brooks, Sagebrush. Dan Theodore, a serious student of BP ballistics who primarily hangs out on the Shiloh Sharps forum, has designed many of these bullets that have proved quite successful in various competitions over the past 10+ years.

Technically the Money bullet is a spherically blunted tangent ogive nose.  You can see it here.

Dan's original spec for that bullet considered more than just the nose itself, but the length, nose to shank ratio, lube groove depth and width, and probably some more factors.   

The Buffalo Arms version I use in my .45-70 does seem to shoot well, but it's a little different than Dan's original design.  Although he has different versions of different chamber designs.
