Lapua Twist rate recomendations?

[TrxR]

Is there anywhere a person could find the recommended twist rate for Lapua Bullets? Im mainly looking for this info for 155 Scenars and 185 Scenars for a 308.

Thanks

Twist rates are based on length not weight. If you know bullet length google { greenhill formula} Plenty of guys here experienced w/ .308 can give you practical input.

You will find most of this kind of info listed by weight as it is more convenient and no one has yest figured out how to pack more weight (enough to matter) in the same length of the same caliber and same composition bullet................VLDs and such notwithstanding.

TrxR,
Might want to get hold of Kevin Thomas, Lapua Rep who also posts on this blog. Kevin competes and shoots several of the Lapua Bullets in his .308, not to mention his knowledge of specific bullets manufactured by Lapua and their performance in different manufacturer's barrels having all sorts of twists.

Try this calculator. Just plug in the parameters and look for a stability factor between 1.5 and 2.0
