Ron, I forgot to add in some information... If you have an opportunity you might do some research on its processor the Devel Bullet. The gun smith that invented it had a very difficult time in life but it was/is a great bullet. Charlie Kelsey was the 'smiths' name.

Mike,
I ran numbers on this bullet. Did I give them to you? I know the BC is probably low but just curious what it is.

Yes you did and yes I did - can not find it right now but I will and it is low.

Found it: BC 0.140

I certainly second this statement.
Those skivvies, or whatever they're referred to, make this bullet very effective. What an innovative design!

Yes for sure!!

Since the plastic sabots are not included, what do you recommend?

Well that's still a 150 yard bullet. Looks like it is better then a mushrooming bullet like Dave said!!

Yes, I doubt that it was never meant to be a long range bullet. It was built to be effective!

You really do not have a lot of choices as the bullet is a .458 bullet - although there is a also a .452x250 XP - then the sabot choice is expanded a lot.

Ron will have to tell you for sure but I would think he was probably using a MMP 458x50 sabot.

I don't know the guy but I was under the impression that he FIRST designed them for the SOCOM then started making them for ML's. Since the .458 SOCOM is generally a very short range weapon it wouldn't surprise me at all that they are limited to around 150 yards. I know mine gets iffy to say the least at ranges beyond 150. I've stretched it to 200 a handfull of times on hogs using both the RN and FN 350 gr Interlocks with good results as far as kills. A couple passed through on rib to rib and one through the neck. The rest were shoulder shots with the bullets landing in the off shoulder. I would expect these to MAYBE pass through at 200 on shoulder to shoulder on medium hogs since the BC is only .040 lower than the RN (Hornady Interlock 350 RN is .189) but these seem to penetrate MUCH better at lower velocities.
