I have a Rem 700 in 243 Win with a 9 1/8 twist.

That means I can use bullets 100 gr and under.

Right?

I would like to try some low wt bullets for long range tartget work.

300-500 yds.

Thoughts??

You should be good to go, here's a link with calibers, twist rates and bullet weight. It is at the bottom

My 10:1 shines wth the lighter bullets, but not 100s. You'd probably make out fine with something like the Sierra 85-grain HPBT. Dunno about 55s.

I thought heavier bullets were used to shoot longer distances since they are less prone to be pushed by the wind. My .243 Rem 700 shoots both 65gr. V-Max and 100gr. SP with about the same accuracy.

You should be fine with anything between 70 gr. to 100 grains .
Only when playing with the extrme numbers like 55-58 gr. to 107 gr. would you notice any real quirks , and maybe not even then .
For longer ranges however , I think you'll eventually decide , that heavier is better .
