i know lighter grained bullets have faster velocity but is their any advantages of a heavier grain and advantages of a lighter grain?

like whats the advantage of a 230 grain 45 acp and whats the advantage of a 165 grain 45 acp.

I'm just another damn yankee with a loaded gun looking for some fun!

The 230 grain bullet should be running around 850 fps. The 165 grain bullet should be around 1050 fps or higher. The lighter bullet will have more rocoil than the 230 grain bullet. I use to shoot a 155 grain bullet for the 45 acp and it was running 1140 plus I had a comp on my pistol so the was no muzzle jump.

there is a fine line. I usually look at energy delivered at impact. obviously the faster something is going, the harder it will hit. Also the heavier it is, the harder it will hit... so you have to find the medium between the two. Also with JHP's you want to make sure the projectile is traveling fast enough for proper expansion.

Heavy VS Light

The heavy bullets vs the lighter bullets differences are more easily noticed at long range shooting. The heavier bullets (in rifles) require a faster rate of twist from the gun's barrel. The faster rate of twist makes the heavier bullets more stable in flight. Take the 5.56 MM or .223 for example. The 50-55 grn. bullets in those cartridges can be shot with acceptable accuracy (M.O.W.= Minute Of Whitetail) but, the heavier 60 or 62 grn. bullets don't do as well and aren't as accurate out of the slower twist rated barrels at long ranges. From 100 yards or less, the differences wouldn't be noticed.
