Bullet/Sabot Diameter
This may sound strange but since I started looking
for a bullet/sabot combination, for my Omega, I have
a question. If you have a sabot of .451 load a .451
bullet what is the exact dia. of the combination?
I have some .451 Harvester crushrib sabots and .451
300gr. Barnes expander bullets, this is why I'm
asking. Trying to find time at the range but mother
nature has been taking her wrath out on West Ky.
Its either raining or snowing or like the past couple
of days all the above. Any info will be appreciated.

Wellll, that is a difficult question, because it depends on the sabot and the sabot manufacturer.
It use to be that Barnes bullets came with a Hornady sabot or what might be an MMP HPH-12 sabot. The bore diameter that this was designed to fit is .507 to .508 with a .452 bullet. With a .451 reduce that .001.
The Harvester, if it isn't a TC Mag express, is designed to accept a .451 or .452 bullet. With a .452 bullet it will go down a .505/.506 bore and with a .451 bullet again subtract that .001.
The "crush rib" is thinner yet and will go down a .504/.505 barrel.
If you measure the outside of the sabot with the bullet insterted, not at the cup but at the petals it will measure something greater than these bore sizes because you need to squeeze the petals across and down the lands and down into the grooves to create rotation. Another thing that makes a difference, what type of plastic or polymere is the sabot and how plyable is the material.Of course the warer the sabot or the barrel the more plyable the sabot becomes, which is OK if the sabot does not skip by the grooves getting little or no rotation. That is why it can not be to loose but it does not have to be as tight as some are.
hope this means something to you - but this is my understanding...

RE: Bullet/Sabot Diameter
Are you asking what is the outside diameter of the sabot in relation to the bore of the rifle?
I think that will vary from sabot to sabot. All I can sayis I have found the .451 diameter bullets tend to load easier then the .452 diameter. If your Omega is not a tight bore hard loader, I think you will like the way the 300 grain Barnes Expanders shoot. Out of my Knight rifles they are a very accurate projectile. I just hate their price.
In my Thompson Center rifles I have found the Shockwaves to be the best projectile for my rifle. I was surprised when I read posts that the Shockwaves are hard to load. Now I admit the first time I loaded a Hornady SST (same bullet as theShockwave)and a harvester sabot I broke my short starter trying to push it into the bore. So sabots can make all the difference in the world.
Sabotloader and Triple Se7en are the people I turn to when I have a sabot problem and they always have the right answer...
Good luck with your rifle and the weather...
