Type I Carcano Questions

[CINDERS]

I would research what ball ammunition was doing but as a guide I dug out some old Hornady 4th editions books one Reloads the other Ballistic charts using the 160gn #2640 bullet driven at 2000ft/sec for a reasonable load, as in the books I have have the max it can be driven is 2200ft/sec, I know things have become better with the powders but this is just from old books without getting into the new ones I have to keep it reasonable.

IMR 4350 35.6 grains = 2000ft/sec COAL = 2.970" therefore basing this speed/projectiles flight ;

For a 100 yard zero = 100 yds - 0, 200 yds - 10" Low, 300 yds - 35.5" Low,
For a 200 yard zero = 100 yds - 5" High, 200 yds - 0, 300 yds - 22" low,
For a 300 yard zero = 100 yds - 13.3" High, 200 yds - 15.2" High, 300 yds - 0. (Looks like your rifle is zeroed for 300yds could be doing 2200/fps given your 100yd data.)

FPE @ 100yds = 1077 Ft/lbs
FPE @ 200yds = 808 Ft/lbs
FPE @ 300yds = 610 Ft/lbs

300yds looks the goods as the hold under sighting is not that bad given there is only 1.9" difference between 100 - 200 yds
***Again no liability accepted using these loads quoted***
