I have a 338 Lapua 28" barrel pushing 2750fps. Would like something a little faster. I have a 30" Lilja 1-10 Twist, #8 Contour at the smiths right now. I would like some opinions on which version of 338 Improved would get me close to 3000fps. Thanks in advance.

Re: Advice On Best 338 Improved

What bullet are you shooting? 300 SMK, or Scenar?
 
Re: Advice On Best 338 Improved

I would look at your reloading data. I am driving the 300 SMK in my AIAWSM 338LM with a 1:11" twist 27" barrel at 2770 fps. Also, how far do you want to push this projo?
 
Re: Advice On Best 338 Improved

338 edge. very fast. not really an improved but very fast and easy to make.
 
Re: Advice On Best 338 Improved

A 338 EDGE with a 30" tube will get you to 2850fps but not 3000.
You will need to look at the 338-378 Weatherby or 338 Lapua AI, but they will get you to 2900-2950
338-408 AI will get you to 3150-3200 with the 300gr SMK

Thanks everyone,
The 338 Lapua AI is probably what I will go with. I know there are several variations of this. I already have 200 Lapua cases, so will probably stick with it.
I am not planning on shooting any further than I already do with the 338 Lapua. Would like to push it a little faster and flatter. 2900-2950fps sounds fine to me.

I just had my edge out this weekend and got 2930 out of a 300 smk over 93.5 gr of H1000.

I have a 338-378 with a Lilja 34 inch 1 in 10 twist tube. I shoot 300 SMK at 3050 with 107 grains 5010 in 30 degrees F. It actually shoot a tighter group at 2950 though.
