"Approach these loads with caution as you would any off the net loading data. These loads may seem low power to us but they are very close to many black power and muzzleloader that brought a lot of game in their time. They are also super economical as to powder used if you have a mold, lead and primers"
Low & Slow: reduced loads
1. .308 Winchester
a. 26 inch barrel with a 220 grain NEI .308 cast bullet over 3 grains of Clays is almost silent
b. 24 inch barrel with a 150 grain RCBS bullet, 3 and ½ grains was needed and it was like a loud cap gun.
c. 150gr cast bullet* load 13 grs. of Red Dot in .308 or .30-06 at about 1600 fps
d. 170gr, cast bullet* 13 grs. of Red Dot in .308 or .30-06, about 1500 fps
e. 200gr. cast bullet* 13 grs. of Red Dot in .308 or .30-06, about 1450 fps
