6mm bullet drop

[Hawkeye7br]

Can someone supply me with the following info? I'm shooting both 87 & 100 grain bullets at 2300-2400 fps. I need to know how far each one drops at 300, 400, and 550 yards when starting with a 200 yard zero. I'm away from home for a few days and don't have my reloading books available.

Thanks in advance.

What 87, and 100gr bullets?

2300-2400 fps? That is really slow for 6mm. Are you sure about that bullet speed? My .243 is over 3,000 with those bullet weights and even my 6mm AR was over 2700 with those bullet weights.

If your speed is really that slow, I would just use standard come-ups for 30 caliber.

Running a 6br with a Sierra 85 grain spitzer flat base at about 2350 I think and a Hornady 100 grain spitzer at (best guess about 2300, using 24.3 grains of AA 2015br. 15 inch barrel loses a lot of speed compared to a rifle length 243. I'm travelling and have no access to a reloading manual with bullet drop tables. I have 200 yard zeroes for each load, but need drops (in inches) for the 300, 385 & 500 meter targets. Thanks!!

For the 87 grain load: -38.7" at 400 yards, -80.4" at 500, -142" at 600 assuming standard SP. A tipped bullet will reduce those drops by about 20"
For the 100 grain load: -36.2" @ 400, -74.8" @ 500 and -129.8" @ 600 with a BTSP
