The lowest is probably the Sierra HP 1800 at 90 grain.

The weight of the bullet. They can range from 25 grain (Small rifles) to over 400 grain for big game.
Grains refer to the bullets weight. A 40 grain bullet weighs four grains more than a 36 grain bullet. It's a little heavier, that's all.

The reference to grains means the weight of the bullet.
Remington .270, 150 grain.
The muzzle velocity of a Winchester .30-30 varies depending on the load and the bullet, but we can ball park things a bit. With a "standard" load and a 110 grain bullet, it's about 2,690 fps (feet per second). For a 130 grain bullet, about 2,500 fps. A 150 grain bullet cuts it to about 2,400 fps. With the 170 grain bullet, it drops to about 2,200 fps.
The heaviest bullet in my reloading manuals for the .380 is a 120 grain cast bullet.
Depending on the type of Bullet your using the maximum range of a 270 Win. will be between 350-600 yards, I've gotten my 270 to reach out to 600 yards with the scope maxed out on evaluation, I've only been able to do this with the Remington Express Pointed Soft Point 100 Grain round. Muzzle Velocity of that round is 3320 FPS with makes it about 400 FPS faster then most of your 130 Grain rounds. Hope that helps.
