338 Caliber - Cutting Edge vs Badlands

[harry_x1]

Measured 5
All were .3382
The sealing area to measure is just ahead of the boat tail junction.
CE uses a pressure band to seal

Apologies for multipe questions....but outside of bore slugging is there a good way to measure bore and or groove dia? Maybe some kind of guides etc? I have couple of multimeters available for use. thanks

Not really
You could set it up in a lathe or possibly another solid fixture and sweep the bore with an long stem indicator
Use a cleaning rod and tight patch to check twist and possibly feel any variation in force necessary though it is difficult to gauge ends like that

Might consider talking to the smith who cut your barrel.

Hi all,

I have been shooting 338 300 Gr Berger OTMs for a while but now plan to shift to solids. One reason is better ballistics (Velocity and BCs) and I am told that solids perform better pass trans sonic speeds.

I am contemplating between 285 gr Badlands ICBMs and corresponding bullets from Cutting Edge. Anyone has any experience with both of these brands/bullets in 338? If yes, request share your experience. Seems majority is using cutting edge, but on paper the BC of Badlands looks significantly better.

thanks for sharing your knowledge.

Solids do NOT have better ballistics. Impact signature is almost non-existent with solids.

I noticed one more thing. Barrel after firing (Badlands) has excessive copper fouling and almost 100% of that fouling is concentrated between middle of barrel till crown. See video at link below. Does that indicate something? Why is the bullet not leaving any copper fouling in first part but starts heavy copper fouling in second half?

How so when they can have a better BC than a heavier cup/core and and you can drive the lighter bullets faster.
My 338 edge.
300 OTM = I think a .421G at 2900 fps.
285 badlands =.493G7 at 3000 fps
I use the exact same powder charges for both 96.5 of N570.
Impact signature is definitely less and why I typically wouldn’t recommend solids for anything under a .375.

Since you’re not having pressure issues I suspect bore might be a bit loose for badlands and you’re leaking gas.
The CE design with gas rings might be a better option.
