I understand "start low", but too low is unsafe also, so where is "low"??? Carlock's site shows him using 90gr H1000 and 94.5gr Retumbo. The site also says that is "max" in his rifle. His rifle might be a lot different than mine, so what do I do? Do I just drop it 10% and start there, or is there some thing else I should be doing?

Thanks for any and all help!
