Would you be willing to share the details of your rifle?
What bullet do you use?
What speed you get?
Barrel length and taper?
weight?
Sure. Here's the link to the Thread that covers this build:

If you decide in a BAT action, do get the melonited action. Without melonite, the bolt lugs are susceptible to galling. With the melonite treatment, they're a class act. I'll add the link to my thread in a bit.
I'm currently shooting the Badlands Precision 275gr Bulldozer bullets. They're lathe-turned monolithic bullets with an aluminum tip to initiate expansion.
MV is 3,035fps with this Bulldozer bullet. 0.387 G7 BC.
Last year I was shooting the Berger 300gr OTM at a muzzle velocity of 2,925fps.
My barrel is a Bartlein #3"B" contour, with two modifications. The breech shank diameter is 1.305" diameter. The diameter @ 28" is 0.725". Barrel is 28" long with a 4-port Muscle brake. Barrel has been melonited.
See Post #13 in the "The .338 Rogue" thread for a look at my chamber reamer spec drawing.
You could gain another ~50fps if you went with less body taper and a 40-degree shoulder. I'm content with this chamber.
This is on the light end of 338 Lapua Imp rifles. I used a McMillan Thumbhole stock with Edge Technology. McMillan's lightest weight stock. I could have lightened it up further with a Proof Carbon Fiber barrel, and I may some day. This isn't my primary backpack hunting rifle, so I'm OK with it's weight, which is a little under 10lbs. I put a 3.5-18X Swarovski Z5 scope on it, which weighs only 15.9oz.
