Vlad, thank you for the kind reply, it is much appreciated.

You are more than welcome to use this idea, this is what knowledge is all about, we need to share knowledge, then we have achieve something in life, then we have left something behind to the world to work on...

I re-loaded fifty rounds for the .458 Mannlicher Schoenauer today to do some shooting with the ghost ring to learn how to shoot it from different postures and positions...

I will make use of the different sizes aperture I turned on the lathe to see what works with my eyes...

I ordered the 475 gn Impala solid bullets to re-load and will see how effective/accurate these bullets are...will give some feedback ...
