I've been working up a load for deer season. This is out of a, new to me, rem 700 adl manufactured in 1975.
Started with 150gr rem core lock over varget (47, 48, 49, and 50gr) The first three charge weights shot around 2.5-3" at 100yds. the 50gr load shot about 5". I'm about out of the core locks so I found some hornady 165gr btsp locally and tried them. Loading them over varget (48-49.5gr) all groups were between 1.5-2" at 100yds. The 48gr load appeared the most consistent so I plan to work with that load some more.
Is there a way to guesstimate the velocity of a 165 gr bullet over 48gr varget out of a standard remington barrel (22" I think)? And also can a trajectory be calculated? I can shoot at 100 and 200 yds at the local range but I would like a rough estimate of the drop at 300 or 400 yds. I should have access to a range that is at least 300 yds soon and I hope I don't have to waste too many rounds getting on target!
Don't worry I won't be trying to shoot any deer at 300 or 400 yds. Just want to try my hand at some longer ranges.
What's your SOP for working up a new load? So far, I've been selecting a bullet and appropriate powder and trying different charges until I found the best group.
