However I know of no hunters who use only 50grs volume of BH209 for hunting. But here's the ballistics facts using the information from the BH209 site and an average hunting charge of 110grs volume with the 290gr TMZ bullet.
NOTE: All muzzle velocities are approximate, given its from the BH209 site and not from a specific barrel.
MZ velocity approximately.... 2,066fps
Velocity at 25yds................. 2004
Velocity at 100yds............... 1741fps ........... 1953fpe
Velocity at 200yds............... 1427fps ........... 1312fpe
Velocity at 300yds............... 1151fps ........... 853fpe
If the above is true, then the bullet is going to function perfectly at the most average BH209 charge for hunting, well within most shooters maximum hunting range. CLOSE TO 300YDS.
Drop it down to just 80grs volume at 1,634 fps, it doesn't drop in velocity (1,100fps according to Barnes minimum) until 200yds, where the program shows approximately 1160fps. Still WELL within most hunters 100yd or less ranges.
Well within 99% of all muzzleloader hunters maximum hunting range.
Those numbers dont look right either. But according to those the bullet is limited if it works. Just like you saw in rons test, it didnt work at all at 1200fps. But it still would kill whatever it goes thru. Just not what im looking for in any bullet. No limitations at all with the MZ Expander. Just a much better ML bullet obviously!!
