My rifle has a one in 8.5" twist. Sierra suggests 8 twist for their 142, and Berger is happy with 9 for their 140's. The berger 140 has by far the highest BC for this class of bullet, so I'm temped to just go with them. Lapua makes no suggestions, but I've heard a lot of good things about their 139.

It's too bad you can't buy these bullets by the dozen for testing. Here's a business opportunity for you George - buy some of everything and sell "test packs" with 20 or so of each type.

Any of the bullets should work with that twist

The Lapua is a fantastic silhouette bullet. It is very accurate, high BC, not sensitive to seating depth and it has a harder core than other match bullets which enhances its ability to take rams. Look no further.

Mate I am using the 139 Lapuas in my 6.5BR with an 8 twist. They are the best I have found.

What about the Lapua 144 gn FMJBT? I know this was reissued perhaps 5-8 years ago for awhile. But that bullet was not nearly as hard as the original. The original used to be loaded in the Red Box 6.5 x 55 rounds that Champion's Choice had in the early-mid-90's. Now it is back again. Is the new bullet as good as the original?

Back then, I reloaded with the 140 Sierra. Since it was shooting fine, I didn't try the 142 when it came out.
