Re: Which bullet would you go with?
You just don't see high BC light bullets. So your question is kind of invalid. Any class of bullet design from any single manufacturer gains BC with weight.
In 30 cal a light SBT will always have a lower BC than the 190, 200, 220, 240's
I bought 200 Sierra 30 cal 200's just to tune the rifle in with a relativley good BC of .560 I did reload a box of 190 SBT's, But I decided that the 200-240 gr. heavier bullets shot more consistantly
Bullet Name Diameter inches Weight grains Sectional Density Ballistic Coefficients
.308 dia. 200 gr. SBT .308 200 .301 .560 @ 2600 fps and above
.552 between 2600 and 2300 fps
.555 between 2300 and 1900 fps
.560 @ 1900 fps and below
.270 Ackley improved 29 inch 1.250 dia. target barrel 7mm STW 28 inch 1.250 target barrel. I also love my .458 mag for varmints and the biggest game in the world.
