The Shockwaves will probably not shoot well from an Ultra Mag, your bore is .504 and those were bulit for a TC bore of right at .500. Believe me your UMag will shoot the 250 but you will have to go to a Hornady SST with the thicker sabot to get it done. The SW's come with a HPH-24 sabot or a yellow superglide sabot and they are to thin... You will need toget some HPH-12 sabots for the UMag...

The front sight on a UMag will usually work when shooting sabots because they can be shot significantly flatter than conicals. Most people have changed the front sight to shoot the heavier conicals.

When you get conicals you will need to get .504 or .5045 sized conicals to get the proper fit also. If you purchase TC or even NE's they might fall righ to the bottom of the bore.

What powder and what load were you shooting???

For saboted bullets from 200 grain to 300 grain I shoot 110 grains of T7-2f and get outstanding accuracy.

UC, Cayugad, and Cdad, will have to discuss loads for conicals from Whites, but i do know that Cdad talks about shooting 100 grain loads with the 460 Bullshops...

The UMag is a great gun you will really like it when everything comes together...

Here is a 120 yard target with my UMag - it was one of my very first, but mine is scoped...
