What new can I add? The 200gr silver tip winchester loads hit 2480fps from my 20.5 inch barrel. Conley Precission loads the 358win as well. Hornady and Remingtons 200gr pointed bullets work great on deer. I load them to 2488fps and thats two grains under listed max. The 225gr partition is a great one load fits all. I have not hunted with it but get 2430fps with it. So far H4895 work for both weight bullets and burns quick no muzzle flash with my 20.5 " barrel.
