Need Help With Tracer Load --

[John Coleman]

Here are some specs to compare.

M-80 = 145gr@ 2750 fps +/- 30 fps @ 78 ft
accuracy = 5" @ 600 yd (in boxes and clips) / 7.5" @ 600 yd on links
powder charge = 44.0 grains extruded

M-61 = 150gr@2750 fps
accuracy = 9.8" (from metric may be 10")@ 600 yd/549m
powder charge = 43.2 grains extruded

M-62 = 142gr@2680 fps
accuracy = 15" @ 600yd
powder charge = 43.5 grains extruded

Dim trace to min 13,7 m
from the muzzle of the
weapon, visible from
max 92 m to min 777 m
from the muzzle of the
weapon

Maximum pressure limit is the same for all @ 3447 BAR / 50, 000 CUP

Data is from company that uses the same powder for all loads. This makes it easier to compare.

case length = 2.015"

cartridge length - 2.80"

M-80 bullet length = 29.00 mm / 1.1417"

M-61 bullet length = 32.40 mm / 1.2756"

M-62 bullet length = 34.50 mm / 1.3583"

The 30-06 M25 bullet is 144 grains compared to the M62 bullet at 142 grains.

M25 bullet length is 36.50 mm / 1.4370".

M2 (30-06) = 152 grains / 1.3709" @ 2740 fps - COL = 3.30" - powder=47.8gr
accuracy = 7.5" @ 600 yd

M25(30-06)= 144 grains @ 2660 fps - COL = 3.30" - powder=46.3gr
accuracy = 18" @ 600 yd

Dim tracer to min. 13 m from the muzzle of the weapon, visible from max 92 m to min 823 m from the muzzle of the
