Friend of mine operates a website for .35 cal fans.

Dave is a good resource for .35 cal info. He built a Ruger M77 MKII .358 WSM years ago.

I have several .358's... three .358 Win's, two .35 Whelen's and a .358/375 Ruger... none of these loads will help you with your Sambar... I like 50.0 grains of W748 and 200 grain Hornady SP's (#3510) in the .358 Win rifles... killed tons of game with those. I use 80.0 grains of RL-17 with the 225 Accubond in the .358/375 Ruger.
