Go to the range and have some fun..
Every answer you'll get will be different. I was always told 75 to 100 max when I was younger....but with the new loads, who knows. I'm lucky enough to have a rifled barrel with Tru-Glo peeps on it. I'm pretty on to 150 with the Hornady SST sabs...aiming a tad high for some drop compensation.
