We had a man bring a Blaser double here to be regulated for this bullet, in ammo loaded for him by a custom loader.

It was an over under, with some sort of adjustment at the muzzle supposed to get both barrels shooting to the same point.

Never worked!

We shot it so many times, and the closest we could get the two barrels to shoot at 100 yards was 6 inches!

He wanted to use it for leopard hunting!

As to copper fouling, its worse on big bores, and most of time it ain't the bullet its the square footage, big bores have more inside metal to copper plate!! Takes most folks a life time to figure that out did me!!

I load the 250TTSX in my .375, most accurate load, recoil is not bad.

I.used the 235 grain Speer in my 375 Winchester as single shot at 2300 fps.They shot awesome in my Winchester big bore 94 1 inch at 100 yards .They were the most accurate bullets in that gun . I never hunted with.them just shot the heck out of them !
