I have created a spreadsheet attached below with 67 monolithic bullets in .451/.452 and .400 (w/sabot) for a .458 (45-70) Smokeless Muzzleloader rifle. The spreadsheet features manufacturer, product line, diameter, weight, BC, length, method by which it works (expansion, fragmentation, fluid transfer, etc), whether it is tipped, flat base or boat tail, stability coefficient assuming a 1:20 twist rate and 2400 fps, and quantity in a box. You can see comments for some of the cells if you hover over them with your mouse. A zero means that data was not provided by the manufacturer; I used a zero so that the columns would sort properly. I did this for myself, but hopefully, someone else will also find the info useful if they want to experiment with monolithic bullets. Monolithic Bullets for SML 2.xlsx (23.66 KB) |

Iv'e been happy with the barnes tez 250 gr tipped bullet out of my cva scout conversion. 45 gr of imr 4227, wool wad and his ignition. knurl the bullets for tight fit when starting in the muzzle with A short starter. they kill very well.

I actually buy the remington branded bullet which is the same bullet with a tan/gold tip. they seem to have better prices on those, they have called them accu tips and also expanders. flat base.

Hueff looks like you are pretty serious. I will be interested in seeing what you come up with.

Yes it will be interesting to see how they all pan out.
I currently shoot the .4085 Hammer bullets in 2 of my .40s full formed and they do very well as a hunting bullet but keep in mind they are full formed.
Most bullet manufacturers get pretty optimistic on their BCs, it sells more bullets.
My hats' off to Kyle for publishing real world BCs on his bullets.
Keep in mind most copper bullets are pretty hard compared to a cup and core bullet, you can anneal untipped models to make them soft and easier to obturate which is the BIG hurdle with mono bullets as land riders, getting the bullet to swell enough to engage the rifling can be a chore which is why many recommend using a saboted .40 cal pill in a .45 bore.
I'm not trying to discourage your venture, it will be interesting to see the results but many of us have been down that road with mixed results.
Mono bullets have 2 big problems in our world
1. getting them to obturate
2. very low BC for bullet weight
As long as you can deal with those 2 obstacles you are in the money.

I don't see the .458 Hornady monoflex on there. OR you have it listed as .451 by accident. Nice spreadsheet though!

The Hornady Monoflex I have listed is the muzzleloader version Monoflex ML which is 0.452" in diameter. I did not include any .458 monoflex bullets, as I am not going to be pursuing fullforming of monolithic bullets. |
